	we have those structures, but *don't* define them if we have

	screws up AIX.
	(struct emacs_tty): Test those symbols, instead of the ioctl

	Fx_set_face, Fx_get_face): Removed.
	(syms_of_xfns): Remove defsubr for Fx_set_face.

	Arrange for font names to get fully resolved - no wildcards.
	* xfns.c (x_set_frame_parameters): Store the value in the frame
	parameter alist before we call the setter function, so the setter
	function can touch up the value if it chooses.
	(x_set_foreground_color, x_set_background_color): Call
	recompute_basic_faces, so their GC's will reflect the changes.
	(x_new_font): Add extern declaration - this returns a Lisp_Object
	now, the fully resolved font name.
	(x_set_font): Accept the fully resolved name from x_new_font, and
	put it in the frame's parameter alist.  Call recompute_basic_faces.

	(if no match), or Qt (match, but unacceptable metrics).
	* xterm.c (x_new_font): Don't call init_frame_faces.

	* xterm.c (dumpglyphs): Remember that the default faces can have

	* xfns.c (Fx_list_fonts): Remember that FACE may not have a font
	specified.  Don't specify 30000 as the maximum limit on the number
	of fontns returned  - 2000 is more reasonable.

	* xfaces.c (build_face, unload_font, free_frame_faces): Don't
	forget to block input while making X calls.

	Treat faces as structures specifying modifications to the frame's
	parameters, rather than things which need to specify a complete
	set of parameters by themselves.
	* xfaces.c (init_frame_faces): Don't set up the two frame display
	faces by querying the GC - just leave all their fields blank, and
	call recompute_basic_faces, letting build_face do the work of
	consulting the frame when necessary.
	(recompute_basic_faces): New function.
	(compute_base_faces): New function for obtaining the "identity"
	for compute_char_face and compute_glyph_face.

	* dispextern.h (struct face): New field - `copy', to help us with
	resource allocation.
	* xfaces.c (free_frame_faces): Do free the first two faces; don't
	free anything from a face that's a copy.
	(intern_frame_face): Mark every face we intern as a copy; its
	resources are actually a combination of the real faces.
	(Fset_face_attribute_internal): No need to check if we're trying
	to free one of the frame's GC's; they never enter into the
	picture.

	* casetab.c: Fix formatting, so as not to confuse etags.

	* xfns.c (Fx_list_fonts): New function.
	(face_name_id_number): Add extern declaration for this.
	* xfaces.c (face_name_id_number): Make this externally visible,
	and make the FRAME argument a FRAME_PTR, not a Lisp_Object.
	(compute_char_face): Call face_name_id_number properly.

	* xfaces.c (unload_color): Don't free the pixel for now.

	* xfaces.c (merge_faces): You can't tell if a font is a
	character-cell font or not by testing whether or not it has a
	per_char table.  They all do.
	* xterm.c (x_new_font): Same deal.
	* xfns.c (Fx_list_fonts): Same deal.

	* m/iris4d.h: Dyke out the section which specifies how to get the
	load average.

	internally by build process.

	* keyboard.c (Fcurrent_input_mode): Use XFASTINT to build the last
	element of the return value, not XSETINT.

	* mem-limits.h [__osf__ && (__mips || mips)]: #include
	<sys/time.h> and <sys/resource.h>.
	(get_lim_data): OSF wants a definition like BSD4_2's.
	* s/osf1.h: #include "bsd4-3.h", not "s-bsd4-3.h".

	* ymakefile (LIBX): Put LD_SWITCH_X_SITE before the libraries, so
	it actually has an effect.

	Some makes can't handle form feed characters in their makefiles.
	* s/usg5-3.h: Remove form feed.
	* s/template.h, m/template.h: Remove form feeds.

	* xfns.c (x_set_font): Report the error message properly.

	* xfns.c (Fx_parse_geometry): No need to call check_x here; it

	* s/linux.h (HAVE_SETSID): Defined.

	using GCC.
	* m/iris4d.h (NEED_SIOCTL): Move this to...
	* s/irix3-3.h (NEED_SIOCTL): ... here; apparently it's not
	necessary in irix4-0.h.

	already declares this elsewhere.
	(PTY_TTY_NAME_SPRINTF): #undef this before re-#defining it.
	* m/ibmps2-aix.h, m/pfa50.h, s/hpux.h, s/isc2-2.h, s/linux.h,

	* config.h.in (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Change the

	xfree on the command line of this compilation.

	* s/sco4.h: (TIME_WITH_SYS_TIME): This is no longer needed.

	* s/linux.h: Remove copyright notices by Michael K. Johnson and
	Rik Faith.  They have both sent in papers now which make their
	changes public domain.

	* sysdep.c (sys_suspend): Set synch_process_alive, so that
	wait_for_termination has something to wait for.

1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	after pre-command-hook runs.

	* xterm.c (x_find_modifier_meanings): If some keys are meta and alt,
	make them just meta, not alt.

1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	Some time-handling patches from Paul Eggert:
	* editfns.c (Fcurrent_time_zone): Take an optional argument specifying
	what (absolute) time should be used to determine the current time zone.
	Yield just offset and name of time zone, including DST correction.
	Yield time zone offset in seconds, not minutes.
	(lisp_time_argument, difftm): New functions.
	(Fcurrent_time_string): Use lisp_time_argument.
	* systime.h (EMACS_CURRENT_TIME_ZONE, EMACS_GET_TZ_OFFSET,
	EMACS_GET_TZ_NAMES): Remove.
	* config.h.in: Add HAVE_TM_ZONE.

	Some more changes from Michael K. Johnson for Linux.
	* s/template.h: Mention that you should #define HAVE_TERMIO or
	HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
	* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
	tcsetpgrp to *pgid; it's just a status value.
	* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
	systems using XFree386, and perhaps is inappropriate in general.
	* m/intel386.h: #undefine the integer size macros, since the Linux
	<values.h> file #defines them itself.
	* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
	fails, fall back on ULIMIT_BREAK_VALUE.
	* process.c: Linux needs the WAITTYPE, etc. definitions.
	* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
	no need to use SYSV names.
	* s/linux.h: New file.

	Some changes from Michael K. Johnson for Linux.
	* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
	#defined.  That lets the system provide it, if it has it.
	* syssignal.h (sigmask): Only define this if <signal.h> hasn't
	given us a definition already.
	* syssignal.h (sys_sigpause): Fix argument in prototype.
	* sysdep.c (init_signals): The masks are called empty_mask and
	full_mask, not signal_empty_mask and signal_full_mask.
	(signal_handler_t): Moved ....
	* syssignal.h: ... to here.
	* systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct

1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* fileio.c (Ffind_file_name_handler): Check that FILENAME is a
	string.

	* process.c (wait_reading_process_input): Undo change of April
	29th, since that re-introduces the race condition the comments are
	warning about.  Call clear_waiting_for_input before calling
	status_notify, though.

	* process.c (wait_reading_process_input): Don't forget to call
	clear_waiting_for_input when we exit the loop because process
	input has arrived.

        Changes for Silicon Graphics Iris 5D.
	* unexelfsgi.c: New file; like unexelf.c, but tolerates program
	segments above BSS.
	* m/iris5d.h: New file.
	* s/irix5-0.h: New file.

	* xdisp.c (display_text_line): If the newline (or C-m, in
	selective-display) has a non-default face, apply that face to the
	remainder of the line, so that the fill occupies the entire line.

	* xterm.c (x_new_font): Tell the frame display faces about the
	newly chosen font.

	Make sure that all the display faces use fonts of the
	same dimensions as the default face, so as not to confuse the rest
	of the redisplay code.
	* xfaces.c (same_size_fonts): New function.
	(merge_faces): Only merge in a new font from the FROM face if it
	is the same size as the font in the TO face.

	* xfns.c (x_set_menu_bar_lines): Minibuffer-only frames can't have
	menu bars.

	* keyboard.c (read_key_sequence): Don't lay down an unwind_protect
	to restore the original buffer until we actually get a mouse click.

	* window.c (window-dedicated-p): Doc fix.

1993-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xterm.c (XTread_socket): Turn off ControlMask for XLookupString.
	* keyboard.c (make_lispy_event): Controlify here.

1993-05-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xdisp.c (redisplay_window): Make the scrollbar reflect the
	extent of the visible region, not the whole buffer.

	* xfaces.c (free_frame_faces): Don't free the resources from the
	first two faces.

	* lisp.h (malloc, realloc): Declare these to return void *, to
	avoid conflicts with ANSI header files.

	* sysdep.c (reset_sys_modes): Test the return value of
	EMACS_SET_TTY properly.
	* systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Document the return
	values.

1993-05-16  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* config.h.in (STDC_HEADERS, TIME_WITH_SYS_TIME,
	CRAY_STACKSEG_END, STACK_DIRECTION): Add #undef clauses for these,
	since otherwise the autoconf tests in configure.in won't do us
	much good.

1993-05-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* buffer.c (overlays_at): New arg EXTEND.
	(Foverlays_at, Fnext_overlay_change): Pass 1.
	* xfaces.c (compute_char_face): Pass 0.
	Try first with small overlay_vec, then use a big enough one.

	* lread.c (syms_of_lread): Make Vcurrent_load_list ordinary Lisp var.
	Set up Qcurrent_load_list.
	(readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.
	(build_load_history): Do nothing when loading pure files.

	knows something has changed.

	* xfaces.c (unload_color): Don't try to unload the standard black
	or white pixel.

	More changes from David Mackenzie.
	* ymakefile (emacs): No need to edit srcdir into a lisp file and
	then load it; we can just take advantage of the PATH_DUMPLOADSEARCH.
	(crt0.o): Remember that crt0.c is in ${srcdir}.

        Install David Mackenzie's patches to make ${srcdir} work.
	* Makefile.in (srcdir, VPATH): Get this value from the top-level
	Makefile.
	(xmakefile): Use ${srcdir} to find the files from which we produce
	xmakefile.  Edit the values for srcdir and VPATH into xmakefile.
	* ymakefile (srcdir, VPATH): New definitions for the Makefile
	to edit.
	(ALL_CFLAGS): Remove `-Is' and `-Im'; add `-I${srcdir}', and

	* process.c (wait_reading_process_input): If we're running
	Solaris, it's not necessary to check if we should redeliver SIGIO,
	according to David Mackenzie.
	* s/sol2.h: #include "usg5-4.h", and #define const.

	* systime.h: Borrow CPP sequence from getdate.y to include the
	proper combination of <time.h> and <sys/time.h>.

1993-05-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* window.h (struct window): New slot region_showing.
	* xdisp.c (mark_window_display_accurate): Set region_showing fields.
	(redisplay_window): Update region_showing field.
	(display_text_line): Set region_showing to t if will show one.

	* xselect.c (Fx_selection_exists_p): Handle nil, t as SELECTION arg.
	Don't die if SELECTION is not recognized.

	* dispnew.c (direct_output_forward_char): Just give up
	if region is being highlighted.

	* xdisp.c (redisplay, redisplay_window): Don't use the cursor-motion
	special-case code if the region is or was highlighted.

	* xfaces.c (compute_char_face): New args REGION_BEG, REGION_END.
	Don't sort if noverlays is 0 or 1.

	* dispnew.c (direct_output_for_insert): Pass those args.

	describing the region if the mark is transient and active.

1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* buffer.c (Fmove_overlay): If the overlay is in no buffer and the
	BUFFER argument has been omitted, put it in the current buffer,
	for symmetry with move-marker.

	* buffer.c (Fdelete_overlay): Make the overlay's markers point
	nowhere, not at 1.  Do this after calling redisplay_region, so
	that code knows what section has changed.

1993-05-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xdisp.c (display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.
	* keyboard.c (command_loop_1): Don't do it here.

	* keymap.c (access_keymap): Handle any length vector.
	(store_in_keymap): Likewise.
	(Fcopy_keymap): Likewise.

1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* buffer.c (Foverlay_start, Foverlay_end, Foverlay_buffer,
	Foverlay_properties): Functions moved here from subr.el.

1993-05-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xfaces.c (compute_char_face): When merging the overlays,
	traverse sortvec, not overlay_vec; the latter isn't the one we
	sorted.

	* xterm.c (dumpglyphs): Give the cursor higher priority than the
	face specified by the glyph under it.

	* xterm.c (dumpglyphs): Move the underline up a row.  I dislike
	the way X addresses pixels.  Quickdraw is much nicer.

	* xfaces.c (intern_face): If the face has a GC, but it's not the
	default or modeline face, abort.  Nothing but those two faces
	should have a GC *and* be passed to intern_face.
	(compute_char_face, compute_glyph_face): After copying
	the frame's default face into face, to use as a base case for
	calculation, set the `gc' member to zero; that way we don't have
	things lying around that look like display faces but aren't.

	* xfaces.c (intern_frame_face): When copying the new face into the
	frame's face array, remember that the number of bytes to copy is
	sizeof (*new_face), not sizeof (new_face).

	* xfaces.c (compute_char_face): Assume that W is displaying the
	current buffer.  Abort if it isn't.

	* lisp.h (Lisp_Overlay): New tag.
	(OVERLAYP): New predicate.
	(CHECK_OVERLAY): New type-checker.
	(Qoverlayp): New extern declaration.
	* buffer.c (Foverlayp): New function.
	(Qoverlayp): New atom.
	(overlays_at, recenter_overlay_lists): Abort if we encounter an
	invalid overlay.
	(syms_of_buffer): defsubr Soverlayp; initialize Qoverlayp.
	(Fdelete_overlay): Set the overlay's markers to point nowhere.
	Use CHECK_OVERLAY instead of signalling a special error.
	(Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
	signalling a special error.
	(Foverlay_get): Use CHECK_OVERLAY.
	* fns.c (internal_equal): Define this for overlays.
	* buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
	* print.c (print): Give overlays their own print syntax.
	* alloc.c (mark_object): Treat overlays like conses.

	* lisp.h (FLOATP): Define this appropriately when LISP_FLOAT_TYPE
	is not defined.

	* buffer.c (Foverlay_get): Return Qnil if the requested property
	is missing from the property list.

        The text property routines can now modify buffers other
	than the current one.
	* insdel.c (modify_region): New argument BUFFER.  Select that
	buffer while we prepare for the modification, and switch back when
	we're done.
	* textprop.c (add_properties, remove_properties): Pass
	the buffer being modified as the first argument to modify_region.
	* editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
	current_buffer as the first argument to modify_region.
	* casefiddle.c (casify_region): Same.

	* dispnew.c (direct_output_for_insert): Compute the face of the
	character we're inserting properly.

	* xterm.c (dumpglyphs): Pass the proper arguments to intern_face.

	* xterm.c (dumpglyphs): Don't increment left twice.

	* intervals.c (set_point): Check for point out of bounds before
	checking for an empty interval tree.

	* cmds.c (Fforward_char): Check proposed new position, and then
	set point, instead of setting point to a potentially invalid
	position.

	* lread.c, data.c: If STDC_HEADERS is #defined, include <stdlib.h>
	to get the extern declarations for atof.  That's where it is in
	POSIX.

1993-05-12  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * ymakefile (xfaces.o): Add window.h to the dependencies.

	* xfaces.c (intern_frame_face): Exchange order of arguments, to
	make callers correct.

	* xfaces.c (compute_char_face): Notice the next property change
	location correctly.

	* xfaces.c (face_name_id_number): Return 0 (the default face) if
	the name is undefined.

	* xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
	is an X frame.

	* xdisp.c (copy_rope, copy_part_of_rope): Add face argument.
	(display_text_line): Initialize current_face to zero.   Apply it
	to characters as we write them to the display matrix.
	(display_string): Pass the new argument to copy_rope.

	* xdisp.c (display_text_line): Handle the locations of face
	changes properly.

	* textprop.c (Fnext_single_property_change,
	Fprevious_single_property_change): Pass arguments to textget in
	the right order.

	* ymakefile (xfns.o): Remove duplication of buffer.h in dependencies.

	* ymakefile ($(OLDXMENU)): Remove extraneous call to `rm'.

1993-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keymap.c (Faccessible_keymaps): Use whatever size the vector has.
	(Fwhere_is_internal): Likewise.
	(describe_vector): Likewise.
	(current_minor_maps): Call Findirect_function, so symbols
	can be used in place of actual maps.

	* xdisp.c (display_text_line): Use break; to exit loop at eol.
	Duplicate the short MAKE_GLYPH loop after the main loop.
	If no display table, do obey selective_display_ellipses.
	(copy_part_of_rope): Arg FROM is now Lisp_Object *.

	* xfaces.c: Do include window.h.
	(compute_char_face): Supply third arg of Fget_text_property.

	* keyboard.c (make_lispy_event): Don't set shift modifier for C-^.

	* callproc.c (child_setup): Omit duplicates from new env array.

1993-05-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * fileio.c (ro_fsys) [SOLARIS_BROKEN_ACCESS]: Check for the
        filesystem being ro, since Solaris 2.1 doesn't.
        (file-writable-p): Call ro_fsys.
	* s/sol2.h (SOLARIS_BROKEN_ACCESS): Define this.

	* systime.h: Use the strategy from getdate.y to include the proper
	combination of <time.h> and <sys/time.h>.

	* xfns.c (Fx_create_frame): Use an XLFD name for the default font,
	instead of "9x15" or whatever it was.

	* xdisp.c (display_text_line): Make face-handling code conditional
	on HAVE_X_WINDOWS macro.  Perhaps this isn't the best approach,
	but it'll do for now.

	* xdisp.c (display_text_line): We can't use the FRAME_DEFAULT_FACE
	macro here; that's x-specific.  Just don't pass the second
	argument.
	* xfaces.c (compute_glyph_face): Remove the BASIC_FACE argument;
	use F's default face.

1993-05-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xfaces.c (Fmake_face_internal): Do nothing for non-X frames.

	* dispextern.h (struct face): Add cached_index member.
	* xfaces.c (get_cached_face): Use it to avoid unnecessary
	searches of face_vector.

	* xfaces.c (intern_face): Renamed from get_display_face.

	* xfns.c (x_make_gc): After building the GC's for the frame, call
	init_frame_faces to set up the first two faces.
	* xfaces.c (init_frame_faces): Don't just try to copy the default
	and mode line faces from some other random frame; instead, consult
	the normal_gc and reverse_gc members of the frame, and build the
	faces based on their parameters.

	Adjust the face computation functions to return frame face ID's,
	not pointers to display faces; since we call these functions
	during display construction, we don't want the display faces yet.
	* xfaces.c (intern_frame_face): New function.
	(compute_char_face, compute_glyph_face): Apply intern_frame_face
	to the computed face, and return the frame face's ID, instead of
	calling intern_face and returning a pointer to a display frame.

	* xfaces.c: Describe the facial data structures.  It took me a
	while to figure them out; perhaps this will save someone else the
	trouble.

	Arrange to tell redisplay about changes in overlays.
	* xdisp.c (redisplay_region): New function.
	* buffer.c (Fmove_overlay): Call redisplay_region on the areas the
	overlay has enclosed or left.
	(Fdelete_overlay): Call redisplay_region on the area the overlay
	used to occupy.
	(Foverlay_put): Call redisplay_region on the area the overlay now
	occupies; we may have put a face property on it.

	* buffer.c (Fmove_overlay): Doc fix.

	* xdisp.c (redisplay): If we're doing a thorough redisplay (all
	windows on all frames involved), go ahead and flush the GC cache -
	call clear_face_vector.

	* xdisp.c (display_text_line): Apply faces to characters
	according to overlays and text properties; use
	compute_char_face and compute_glyph_face to figure out what
	face to use, and where a new face starts.
	* xterm.c (dumpglyphs): Use the upper bits of the glyphs to decide
	which frame face to use.  Call GLYPH_FOLLOW_ALIASES to make sure
	we're implementing the glyph table properly.  If we're not using
	the default or mode line face, call intern_face to find a display
	face for the frame face selected by the glyph code.  Implement
	underlining.  Remove the `font' argument; we have to derive this
	from the frame and face anyway.  Change all callers.
	* disptab.h (GLYPH_FOLLOW_ALIASES): New macro.

	* xterm.c (x_destroy_window): Call free_frame_faces.

	The GNU coding standards specify that CFLAGS should be left for
	users to set.
	* ymakefile (ALL_CFLAGS): Set this to the long string of
	compilation switches, not CFLAGS.  Changed all uses.
	(CFLAGS): Make this default to just -g.
	(.c.o): Define new default rule, to make sure that the right flags
	get to the compilations.

1993-05-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (read_char): Exit kbd macro if Vexecuting_macro is t.

	* pwd.h: File deleted.

1993-05-08  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* s/sunos4shr.h: Apply changes from David J. Mackenzie; this isn't
	used by any configuration right now, but he's trying to make it
	work.
	#include "sunos4-1.h" instead of "bsd4-2.h".
	(O_NDELAY): Don't define this.
	(SYSTEM_MALLOC): Don't define this, either.
	(LD_SWITCH_SYSTEM): Remove the definition for this.

	* Makefile.in (DEFS): Remove this; we have configure build a
	config.h file directly, instead of having lots of -D flags.

	* Makefile.in (CFLAGS): Don't make this carry DEFS from the
	configure script; the coding standards say that CFLAGS should be
	left for the user to tweak.

1993-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (do_mouse_tracking): Now static.

	* xmenu.c (Fx_popup_menu): Add a vector of prefix keys for the panes.

	* window.c (Vmouse_event): Var deleted.
	(syms_of_window): Don't make it a Lisp var.

        meta_key a three-value variable to support 8-bit input.

1993-05-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* ymakefile [__GNUC__ && __GNUC__ > 1] (LIB_GCC): Set this even if
	LINKER is #defined.

	* ymakefile ($(OLDXMENU)): Remove the link before we re-create it;
	not all versions of ln have the `-f' flag.  Use the LN_S variable,
	inherited from src/Makefile.

	* Makefile.in (LN_S): New variable, edited by top Makefile.
	(SUBMAKEFILE): New variable, containing all flags to pass to
	recursive makes.

	* config.h.in: Adjust this for use by autoconf's AC_CONFIG_HEADER,
	instead of AC_OUTPUT.

	* xfaces.c (get_display_face): Use face_eql instead of writing it out.

1993-05-06  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* keymap.c (Fwhere_is_internal): If FIRSTONLY is non-nil, avoid
	returning a non-ascii key sequence unless FIRSTONLY is the symbol
	`non-ascii'.

	* config.h.in: Remove mention of GLYPH datatype; that shouldn't be
	a user option.
	* lisp.h (GLYPH, MAKE_GLYPH, GLYPH_CHAR, GLYPH_FACE): New macros.

1993-05-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xfns.c (x_get_arg): Call Fintern, not intern.

	* systime.h [SCO]: Include time.h.
	* s/sco4.h: New file.

	* ymakefile (LIBXMENU): Delete -loldX.

	* emacs.c (main): Handle -display like -d.

1993-05-05  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* s/template.h: Explain the relative significance of the SIGIO and
	INTERRUPT_INPUT macros.

	* ymakefile (buffer.o, insdel.o): Note that these files also
	depend on blockinput.h.

	* blockinput.h (UNBLOCK_INPUT): We cannot assume that SIGIO is
	defined everywhere this file is #included; merge the two
	definitions for defined (SIGIO) and ! defined (SIGIO) into one,
	which calls reinvoke_input_signal if interrupt_input_pending is
	set.
	* keyboard.c (reinvoke_input_signal): New function.

1993-05-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* window.c (Fdisplay_buffer): Add space to prompt.

1993-05-04  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keyboard.c (syms_of_keyboard): Doc fix for
	extra-keyboard-modifiers.

	* lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT, CHAR_CTL,
	CHAR_META): Shift these all up one bit, back to where they were.

1993-05-02  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* keymap.c (Fdefine_prefix_command): Doc fix.

	* ymakefile (C_DEBUG_SWITCH): Undo April 10 change.

1993-05-01  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

1993-04-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* data.c (Ffset): Refuse to set the function value of t or nil.

1993-04-29  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Implement extra_keyboard_modifiers properly.
	* keyboard.c (syms_of_keyboard): Doc fix for
	extra-keyboard-modifiers; use the same modifier bits as we do for
	characters.
	(read_char): Apply all the modifiers in extra_keyboard_modifiers
	to the input characters, so you can get hyper, super, and the rest
	of the gang.
	* xterm.c (x_emacs_to_x_modifiers): New function.
	(x_convert_modifiers): Renamed to x_x_to_emacs_modifiers, for
	consistency.  Callers changed.
	(XTread_socket): Apply x_emacs_to_x_modifiers to
	extra_keyboard_modifiers before setting the state member of the
	event; this will get all the modifiers on ASCII characters.

	* xterm.c (x_text_icon): Don't call XSetIconName; it should be
	unnecessary, and perhaps it's killing the icon pixmap.

	* lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER): New constants, in
	case we need them.
	* termhooks.h (alt_modifier, super_modifier, hyper_modifier,
	shift_modifier, ctrl_modifier, meta_modifier): Define these in
	terms of the CHAR_mumble macros, to avoid having the same thing
	defined in two places.

	* keyboard.c (kbd_buffer_get_event): Don't generate switch-frame
	events if they'd only switch to the frame already selected.  This
	avoids lots of extra switch-frame events when using a separate
	minibuffer.

1993-04-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (Fthis_command_keys): Doc fix.

	* process.c (wait_reading_process_input): Move the status_notify
	call before the set_waiting_for_input call.

	* fileio.c (Fexpand_file_name): Undo last change--too risky for now.

	* data.c (Fdefine_function): New function (same code as Fdefalias).

1993-04-28  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

1993-04-27  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

	* eval.c (un_autoload): Don't try to save old autoload forms when
	we load something in.  Something about the code now conditioned
	out by UNLOAD was screwing up ordinary autoloads, notably of
	picture.el.  When I figure out what, I'll fix and re-enable this
	code.

1993-04-27  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* buffer.c (syms_of_buffer): Doc fix for buffer-display-table.

	* systime.h: Doc fix.
	(EMACS_SET_USECS): Remember that a `usec' is a microsecond, not a
	millisecond.  What's three orders of magnitude between friends?
	* dispnew.c (Fsit_for, Fsleep_for): Remember to multiply the
	`milliseconds' argument by 1000 to get microseconds.

1993-04-26  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

	* fileio.c (Fexpand_file_name):
	Don't remove trailing / from NEWDIR if just "/".

1993-04-26  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* m/ibmps2-aix.h, m/ibmrs6000.h, m/ibmrt-aix.h, m/mips.h,
	m/sps7.h, s/hpux.h, s/usg5-4.h (HAVE_DUP2): Removed; derived by
	configure script.
	* s/hpux.h, s/irix3-3.h, s/aix3-1.h (HAVE_GETHOSTNAME): Removed;
	derived by configure script.

	Arrange for Fy_or_n_p to put off switch-frame events.
	* lread.c (read_filtered_char): New function, which contains the
	code which used to be in Fread_char, Fread_event, and
	Fread_char_exclusive; there was a lot of common code.
	(Fread_char, Fread_event, Fread_char_exclusive): Rewrite in terms
	of read_filtered_char.
	* lisp.h (read_filtered_char): Declare this extern here.
	* fns.c (Fy_or_n_p): Call read_filtered_char, arranging to delay
	switch-frame events.

	* keyboard.c (read_key_sequence): Let the `modifiers' variable in
	the code which deals with KEY being unbound be an int, not a
	Lisp_Object.

	* config.h.in (getenv): Don't test THIS_IS_YMAKEFILE to see if we
	should exclude the getenv declaration; instead, test NOT_C_CODE.
	Per suggestion from Francesco Potorti`.
	* ymakefile (NOT_C_CODE): Define this; it's true, and useful.

	* dispnew.c (Fsleep_for, Fsit_for): Allow SECONDS to be a
	floating point value.

1993-04-26  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

	* sysdep.c (read_pending_input):
	Fix the garbaged-modifiers bug under System Vs previous
	to r4.

1993-04-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Move these into
	functions in sysdep.c.
	* sysdep.c (emacs_get_tty, emacs_set_tty): Here they are.

	* sysdep.c (emacs_set_tty): Call tcsetattr over and over again
	until it does all of what we ask it to, or returns an error.

	* search.c (Freplace_match): Arrange for markers sitting at the
	beginning or end of the original text to float to the
	corresponding position in the replacement text.

1993-04-25  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

	* window.c (Fset-window-buffer):
	Set horizontal-scrolling on a window to zero when
	we connect it to a new buffer.

	* buffer.c: Doc fix.

1993-04-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	Make the modifier manipulation functions more robust.  The old way
	caused a bug once, and probably would again.
	* termhooks.h (alt_modifier, super_modifier, hyper_modifier,
	shift_modifier, ctrl_modifier, meta_modifier): Shift these all
	down one bit in value, to avoid sign extension problems.
	* lisp.h (CHAR_META, CHAR_CTL, CHAR_SHIFT): Fix these definitions too.
	* keyboard.c (lispy_modifier_list): Ignore modifier bits beyond
	what our table of modifier names can handle.
	(apply_modifiers): Don't abort if you see extra modifier bits,
	just remove them.

1993-04-23  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

	* data.c (Fdefine_function):
	Changed name back to Fdefalias, so we get things
	in a known-good state.

	* buffer.h (BUF_NARROWED, NARROWED):
	New macros to test whether a region
	restriction has narrowed the buffer.

1993-04-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* systime.h: Comment fixes.

	* data.c (Fdefine_function): New function.

	* lisp.h (LOADHIST_ATTACH): New macro.

	* eval.c: (defun, defmacro, defvar, defconst):
	Attach symbol argument to the list of globals for the input source.
	(do_autoload): Save the old autoloads, in case we ever unload.

	* fns.c (provide, require): Put appropriately-marked
	conses in the current-globals list.

	* lread.c (readevalloop):
	New argument is the source file name (or nil if none).
	All calls changed.  Do the two-step
	necessary to call build_load_history with the correct current-globals
	list for the current recursion.
	(build_load_history): New function.
	(eval_region, eval_buffer): Call readevalloop with new arg.
	(load_history): New variable.

1993-04-16  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

	* lread.c (readevalloop): New argument is the source file name (or
	nil if none).  All calls changed.  Do the two-step
	necessary to call build_load_history with the correct current-globals
	list for the current recursion.
	(build_load_history): New function.
	(Feval_region, Feval_buffer): Call readevalloop with new arg.
	(Vload_history): New variable.

	* fns.c (Fprovide, Frequire): Put appropriately-marked
	conses in the current-globals list.

	* eval.c (Fdefun, Fdefmacro, Fdefvar, Fdefconst):
	Attach symbol argument to the list of globals for the input source.
	(do_autoload): Save the old autoloads, in case we ever unload.

	* data.c (Fdefine_function): New function.

1993-04-16  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* fileio.c (Fmake_symbolic_link): If a file already exists under
	the link's filename, delete the file which the link
	would replace, not the file the link would point at.

	* config.h.in (volatile): Don't define this to be the empty string
	if some file has #defined HAVE_VOLATILE.

	* emacs.c (SEPCHAR): Instead of defining this to be ',' on VMS and
	':' elsewhere, just have it default to ':' if not #defined, and
	#define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
	* s/vms.h (SEPCHAR): #define this to be ','.
	* s/template.h (SEPCHAR): Mention this.

1993-04-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* s/vms.h (xfree): #define this to emacs_xfree, to avoid case
	conflict with XFree; on VMS, external symbols are case-insensitive.

	* s/usg5-4.h (HAVE_GETTIMEOFDAY): Deleted; ../configure figures
	that out now.

	Changes for Emacs 19 from Thorsten Ohl <ohl@chico.harvard.edu>:
	* s/mach2.h: copied from the Emacs 18.59 distribution.
	Don't define NO_REMAP, define START_FILES as
	`pre-crt0.o' instead.  Define LIB_MATH as `-lm', to override the
	default `-lm -lc' (there is no libc on the NeXT).
	* ymakefile (STARTFILES): Allow config.h to set this value even if
	ORDINARY_LINK is defined.
	* unexnext.c: Fix subdirectories for the machine dependent include
	files for NeXTStep 3.0; #include <mach/mach.h> and
	<mach-o/loader.h> instead of <mach.h> and <sys/loader.h>.
	(getsectbyname): Remove prototype for this; the system #include
	files take care of that.
	(malloc_cookie): New variable.
	(unexec_doit): Set malloc_cookie to the result returned by
	malloc_freezedry.
	* emacs.c (main): Declare malloc_cookie to be extern, so that we can
	get the value set when we dumped and pass it to malloc_jumpstart.
	* systime.h: The NeXT has a timezone function.

1993-04-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* ymakefile ($(OLDXMENU)): Remove $(OLDXMENU) before trying to
	link in a new version.

	* lisp.h (Qrange_error, Qdomain_error, Qsingularity_error,
	Qoverflow_error, Qunderflow_error): Add extern to these declarations.

1993-04-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xfaces.c: Don't include Xmu/Drawing.h.

1993-04-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* Makefile.in (xmakefile): Recognize the -O option with a numeric
	optimization level.

	* ymakefile (C_DEBUG_SWITCH): If we're using version 2 of GCC or
	higher, use -O99 instead of plain -O.

1993-04-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* keyboard.c (command_loop_1): Rebuild menu bar if
	update_mode_lines is set.

        long_to_cons and cons_to_long are generally useful things; they're
	needed whether or not X is defined.
	* xselect.c (long_to_cons, cons_to_long): Moved from here...
	* data.c    (long_to_cons, cons_to_long): ... to here.
	* lisp.h    (long_to_cons, cons_to_long): Add extern declaration.

	* xmenu.c (Qmenu_enable): Definition moved...
	(syms_of_xmenu): ... along with initialization ...
	* keyboard.c (Qmenu_enable): ... to here ...
	(syms_of_keyboard): ... and here.

	* keyboard.c (kbd_buffer_get_event): If we get a selection clear
	or selection request event, but we were compiled without the
	window-system-specific code to handle it, abort.  Don't try to
	call a function which doesn't exist.

	* keyboard.c (make_lispy_event): In the code which processes mouse
	clicks, declare f to be a FRAME_PTR, not a struct frame *; this
	works when MULTI_FRAME is not #defined.

	* xfaces.c (sort_overlays): Define this to be static, as declared.

	* callproc.c (relocate_fd): Make messages string literals, not
	initialized arrays.

	* alloc.c (__malloc_hook, __realloc_hook, __free_hook): Declare
	these extern, not static.  (!)

	* alloc.c (__malloc_hook, old_malloc_hook, __realloc_hook,
	old_realloc_hook): Declare that the functions these point to return
	void *, not void.

        Adjust for autoconf merger.
	* config.h.in: Add extra line to top, in case autoconf gets fixed
	and decides not to add Makefile-style comments to the top of the
	files it generates which we are forced to lop off.
	Indicate that the boolean macros here get their definitions via
	the DEFS Makefile variable.
	Adjust the operating system and machine #includes to use
	autoload's @cookies@.
	(RETSIGTYPE): Give this a default value.
	(SIGTYPE): Set this from RETSIGTYPE.
	(LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Get values via @cookies@.
	* Makefile.in (DEFS): Renamed from CONFIG_CFLAGS.
	(xmakefile): Pass CFLAGS to ${CPP}.

	* buffer.c (Fmake_overlay, Fmove_overlay): New optional BUFFER
	arguments.
	(recenter_overlay_lists): New argument BUF, to use instead of the
	current buffer.
	(Foverlay_recenter): Pass the appropriate arguments to
	recenter_overlay_lists.

	* buffer.c (Fdelete_overlay): Don't assume that overlay is in the
	current buffer.  Don't forget to declare the argument a Lisp_Object.

	* dispnew.c (getenv): Extern declaration deleted; this is done in
	config.h.

	* Makefile.in (tagsfiles): Remove external-lisp from this list of
	files; we're not distributing it, so the normal build process
	shouldn't depend on it.

	* dispnew.c (init_display): Compare the return value of getenv to
	zero before setting display_arg, instead of just using the pointer
	as a truth value.

1993-04-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xdisp.c (message, message1): If noninteractive and
	cursor_in_echo_area, don't print a newline at end of message.

	* fns.c (Fy_or_n_p): Echo the answer just once, at exit.

	* keyboard.c (echo_dash): Do nothing if echoptr is 0.

	* buffer.c (Fkill_all_local_variables): Store each var's current value
	in the buffer's alist entry, before reverting to the default value.

	* keyboard.c (apply_modifiers): Fix typo in sanity check.

	* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
	Remove `extern' keywords - these are the definitions.

1993-04-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* blockinput.h (UNBLOCK_INPUT): Fix typo.
	(interrupt_input_blocked): Make this signed int.

	* search.c (search_buffer): Fix typo in previous change.

	* insdel.c, buffer.c: Include blockinput.h.

	* xterm.c: Fix typo in comment delimiter.

1993-04-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* m/imbrs6000.h: If we're using GCC, define ORDINARY_LINK instead
	of defining LINKER to use cc.
	* s/aix3-1.h (LINKER): Don't use cc for linking command if we're
	using GCC.
	* s/aix3-2.h (SYSTEM_MALLOC): Undefine this.

	* xterm.c (updating_frame): Declare this extern instead of static,
	so it's the same variable as the updating_frame in term.c.
	(XTupdate_begin, XTupdate_end): Don't bother to set
	updating_frame; the term.c functions take care of that for us.

1993-04-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* s/vms.h (EXEC_SUFFIXES): Add definition for this.

1993-03-31  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* xfaces.c: Doc fixes.

	Put interrupt input blocking in a separate file from xterm.h.
	This isn't specific to X, and it allows us to avoid #including
	xterm.h in files that don't really have anything to do with X.
	* blockinput.h: New file.
	* xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
	UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
	(x_input_blocked, x_pending_input): Deleted; there are analogs
	in blockinput.h called interrupt_input_blocked and
	interrupt_input_pending.
	* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
	New variables, used by the macros in blockinput.h.

	* eval.c: #include blockinput.h instead of xterm.h.
	* keyboard.c: #include blockinput.h.
	(input_poll_signal): Just test
	interrupt_input_blocked, instead of testing HAVE_X_WINDOWS and
	x_input_blocked.

	Block the processing of interrupt input while we're manipulating the
	malloc heap.
	* alloc.c: (xfree): New function, to make it easy to free things
	safely.
	(xmalloc, xrealloc): Block X input while doing the deed.
	(VALIDATE_LISP_STORAGE, gc_sweep, compact_strings): Use xfree
	instead of free.
	(uninterrupt_malloc): New function, to install input-blocking
	hooks into the GNU malloc routines.
	* emacs.c [not SYSTEM_MALLOC] (main): Call uninterrupt_malloc
	on startup.
	* alloc.c: (make_interval, make_float, Fcons, Fmake_vector,
	Fmake_symbol, Fmake_marker, make_uninit_string, Fgarbage_collect):
	Use xmalloc instead of malloc; don't bother to check if out of
	memory here.
	(Fgarbage_collect): Call xrealloc instead of realloc.
	* buffer.c: Use xmalloc and xfree instead of malloc and free;
	don't bother to check if out of memory here.
	(Fget_buffer_create): Put BLOCK_INPUT/UNBLOCK_INPUT pair around
	calls to ralloc routines.
	* insdel.c: Same.
	* lisp.h (xfree): New extern declaration.
	* xfaces.c (xfree): Don't #define this to be free; use the
	definition in alloc.c.
	* dispnew.c, doc.c, doprnt.c, fileio.c, lread.c, term.c, xfns.c,
	xmenu.c, xterm.c: Use xfree instead of free.
	* hftctl.c: Use xfree and xmalloc instead of free and malloc.
	* keymap.c (current_minor_maps): BLOCK_INPUT while calling realloc
	and malloc.
	* search.c: Since the regexp routines can malloc, BLOCK_INPUT
	while runing them.  #include blockinput.h.
	* sysdep.c: #include blockinput.h.  Call xfree and xmalloc instead
	of free and malloc.  BLOCK_INPUT around routines which we know
	will call malloc.

	ymakefile (keyboard.o, keymap.o, search.o, sysdep.o, xfaces.o,
	xfns.o, xmenu.o, xterm.o, xselect.o, alloc.o, eval.o): Note that
	these depend on blockinput.h.

	* keyboard.c (parse_modifiers, apply_modifiers): Make sure we're
	not trying to create modifier masks using integers which are
	unrepresentable as lisp values.

1993-03-30  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	New macros NULL_DEVICE and EXEC_SUFFIXES, to give the name of the
	equivalent of /dev/null, and the suffixes used by executable
	files.  This is simple, and helps people porting Emacs to other
	operating systems.
	* process.h (NULL_DEVICE): Give this a default value.
	* process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.
	(Fprocess_send_eof): Use NULL_DEVICE instead of "/dev/null".
	* callproc.c (Fcall_process): Pass EXEC_SUFFIXES to openp.
	Use NULL_DEVICE instead of "/dev/null".
	* s/vms.h (NULL_DEVICE): #define this.

	Rename int-to-string to number-to-string, since it can handle
	floating-point as well as integer arguments.  subr.el defines the
	former as an alias for the latter.
	* data.c (Fnumber_to_string): Renamed from Fint_to_string.
	(wrong_type_argument): Adjust caller.
	(syms_of_data): Adjust defsubr.

	* fileio.c (Fexpand_file_name): Default DEFALT at beginning,
	before expanding it.  But avoid unneeded or infinite recursive expand.

1993-03-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* floatfns.c (Flogb): Undo the change of Feb 22.

	* ymakefile (OLDXMENU): Don't assume that we have symbolic links
	available; use `ln -f' instead of `ln -s'.

	* xterm.c (x_find_modifier_meanings): XDisplayKeycodes only
	appeared in X11R4; for earlier versions, just access the members
	of the Display directly.

	* xrdb.c (get_user_db): Since xrdb.c doesn't #include xterm.h,
	we can't test HAVE_X11R4 to see how we should get the resource
	manager string; cheat.

	* unexec.c (copy_text_and_data): Error message tweaked.

	* systime.h (timezone): Add an explicit declaration for this
	variable under USG 5-4.

	* sysdep.c (read_input_waiting): Set e.frame_or_window, not
	e.frame; the latter doesn't exist anymore.

	* sysdep.c (start_of_data): If ORDINARY_LINK is #defined, we don't
	have the data_start symbol defined, so we'll just use the address
	of environ.

	* s/usg5-4.h: Changes from Eric Raymond:
	If we're doing ordinary linking, define LIB_STANDARD appropriately.
	Give LIBS_DEBUG a null definition; usg5-4 has no -lg.
	#define LIBS_STANDARD as "-lc"; usg5-4 has no -lPW.
	#define NSIG, if it's not already defined.
	#define HAVE_TERMIOS instead of HAVE_TCATTR.
	Provide our own definition of LIB_X11_LIB.

	* s/usg5-3.h (LIBX11_SYSTEM): Eric Raymond says the libraries here
	were slightly wrong.

	* m/intel386.h (LIB_STANDARD): If USG5_4 is #defined, there's no
	need to include `-lPW'; that has been merged with `-lc'.

	* emacs.c (__do_global_ctors, __do_global_ctors_aux,
	__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__, __main): Don't
	define these if ORDINARY_LINK is #defined; in that case, the
	standard linking procedure will find definitions for these.

	* syssignal.h (sigunblock): Add definition which works under SYSVr4.
	* emacs.c (fatal_error_signal): Unblock the signal which we're
	handling using sigunblock.

	* m/template.h, s/template.h: Mention that `etc/MACHINES' and
	`configure' should be updated whenever support for a configuration
	is added or improved.

	* process.c [! subprocesses] (wait_reading_process_input):
	Remember to re-enable polling for input.

	* keyboard.c [POLL_FOR_INPUT] (quit_throw_to_read_char): If
	we're polling for input, abort; input polling should always be
	suppressed while we're waiting for input.

	* keyboard.c (interrupt_signal): Remove extern declaration of
	Vwindow_system; this is no longer used.

	(Fround): Always implement this by calling floor, even on systems
	that have rint.

	* process.c (process_send_signal): Use TERMIOS functions in
	preference to BSD ioctls.  Some systems attempt to provide the BSD
	functions for backward compatibility, and get it wrong.

	* data.c (Fstring_to_number): Skip initial spaces, to make Emacs
	lisp parse consistently on different operating systems.
	#include <ctype.h> to help with this.

	* data.c (Fstring_to_int): Rename this to Fstring_to_number, since
	it parses floats as well as integers.  Fix docstring.
	(syms_of_data): Fix defsubr.
	(wrong_type_argument): Change use.
	(Fint_to_string): Doc fix.
	* lisp.h (Fstring_to_int): Change extern declaration.

	* ibmrs6000.h (C_ALLOCA, STACK_DIRECTION): Only define if HAVE_ALLOCA

	(unix): Define.

1993-02-17  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	just setting the `rows' and `cols' members of the frame, and
	leaving the window tree in complete disarray.

	* dispnew.c (remake_frame_glyphs): When re-allocating the frame's
	message buffer when echo_area_glyphs is pointing at it, relocate
	echo_area_glyphs too.  Same for previous_echo_glyphs.
	* window.h (previous_echo_glyphs): Add extern declaration for this.

	* frame.c (Fframe_parameters): Report the `minibuffer' parameter of
	minibufferless frames as nil, not `none'.
	(Qnone): Remove declaration and initialization for this.  It's not
	needed anymore.
	* xfns.c (Qnone): Add them here; we still accept "none" as a valid
	value for the `minibuffer' parameter.

	* xfns.c (x_frame_params): Remember that the parameters are called
	"auto-raise" and "auto-lower", not "autoraise" and "autolower".

	* xdisp.c (message): Set echo_frame to the frame whose message buf
	we want to use, not to the message buf itself.

1993-02-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* textprop.c (Fadd_text_properties): Put OBJECT arg last.
	Make it optional.

1993-02-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* s/usg5-4.h: #include "usg5-3.h", not "s-usg5-3.h".

1993-02-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xterm.c (x_io_error_quitter): New function.
	(x_error_quitter): Note that this is only used for protocol
	errors now, not I/O errors.
	(x_term_init): Set the I/O error handler to x_io_error_quitter.

1993-02-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	(Fcompare_buffer_substrings): Likewise.

1993-02-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* fileio.c (Fdo_auto_save): If NO_MESSAGE is non-nil, don't tell
	users that buffers have shrunk a lot.  This is called when Emacs
	is crashing, so we don't want to run any code that isn't
	absolutely necessary.  Also, autosave buffers which don't have
	specially handled autosave file names first.

1993-02-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* editfns.c (Fcompare_buffer_substrings): Ignore case

	* fileio.c (Fexpand_file_name): Doc fix.

1993-02-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xdisp.c (message): Use the message buffer of the frame we're
	going to display the message on to format the message, not that of
	the selected frame.

1993-02-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* Makefile (emacs, temacs): Add no-op commands to these rules.

	XWINDOW to selected_window before passing it to window_internal_width.

	* xmenu.c (Fx_popup_menu): Don't forget to turn the frame-relative
	coordinates for the menu position into root-window-relative
	coordinates.

	* lread.c (read1): Although digits followed by a '.' are an
	integer, a single . by itself (like, say, \.) should be a symbol.

1993-01-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* fns.c (internal_equal): Protect the clause for comparing numbers
	of different types with a "#ifdef LISP_FLOAT_TYPE".

1993-01-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s/hpux8.h [__GNUC__] (LD_SWITCH_SYSTEM): Remove -a.
	[__GNUC__] (ORDINARY_LINK): Defined.

	* m/sparc.h [TERMINFO]: Don't define LIBS_TERMCAP.

1993-01-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	(syms_of_buffer): Change DEFVAR; initialize Qfirst_change_hook.
	* buffer.h (Vfirst_change_function): Renamed to Vfirst_change_hook.
	(Qfirst_change_hook): Added declaration.
	* insdel.c (signal_before_change): Change references to
	Vfirst_change_function, and apply Vrun_hooks to
	Qfirst_change_hook, instead of just calling Vfirst_change_function
	directly.

	x-selection-value has been renamed to x-selection.
	x-own-selection has been renamed to x-set-selection, and the order
	of its arguments has been reversed, for consistency with other
	lisp functions like put and aset.
	* xselect.c (Fx_own_selection): Rename to Fx_set_selection,
	reverse the order of the args, and therefore make the type
	non-optional.  Doc fix.
	(Fx_selection_value): Rename to Fx_selection; make the type
	argument non-optional, for symmetry with Fx_set_selection.  Doc
	fix.
	(syms_of_xselect): Adjusted.

	* xselect.c (Fx_own_selection, Fx_selection_value): Remove "#if
	0"'ed code which made cut buffers look like a special selection
	type.

	* xfns.c (Vx_selection_value): Removed extern declaration for
	this; it's never used.

	* data.c (Fcompiled_function_p): Renamed to Fbyte_code_function_p.
	(syms_of_data): Adjusted.

	* data.c (Fnumberp, Fnumber_or_marker_p): Use the NUMBERP macro,
	instead of writing it out.

	* fns.c (internal_equal): If the operands are both numbers,
	compare them numerically, so that (equal 1.0 1) => t.
	Compare Lisp_Compiled objects like vectors.

	Add lisp functions to raise and lower frames.

	* term.c (frame_raise_lower_hook): Define it.
	* frame.c (Fframe_to_front, Fframe_to_back): New functions.
	(syms_of_frame): defsubr them.
	* xterm.c (XTframe_raise_lower): New function.
	(x_term_init): Set frame_raise_lower_hook to XTframe_raise_lower.

	* frame.c: Doc fixes.

1993-01-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	Make the cursor style a frame parameter.
	* xterm.h (struct x_display): Rename the `text_cursor_kind' member
	to `current_cursor'; add new member `desired_cursor'.
	(FRAME_DESIRED_CURSOR): New accessor for new member.
	* xterm.c (x_display_bar_cursor): Rewritten so as not to damage
	the characters the cursor is displayed over, and to handle
	transitions between box and bar styles.
	(x_display_bar_cursor, x_display_box_cursor): Use current_cursor
	instead of text_cursor_kind.
	(Vbar_cursor): Delete external declaration.
	(x_display_cursor): Use the FRAME_DESIRED_CURSOR accessor instead
	of Vbar_cursor to decide how to draw the cursor.
	* xfns.c (Vbar_cursor): Remove definition.
	(Qbar, Qbox, Qcursor_type): New symbols.
	(syms_of_xfns): Init and staticpro them; remove DEFVAR for
	Vbar_cursor.
	(x_set_cursor_type): New setter.
	(x_frame_parms): Add it to the list.
	(Fx_create_frame): Get default values for the cursor type.

	* frame.c (Fmouse_position): Pass the appropriate arguments to
	*mouse_position_hook; the protocol was changed, but this caller
	wasn't fixed.

	* xterm.c (XTclear_frame): Call x_scrollbar_clear.
	(x_scrollbar_clear): New function.

	* xterm.c (XTflash): Totally rewritten.  Only defined if
	HAVE_TIMEVAL and HAVE_SELECT are defined, since we use select for
	our timing.
	(timeval_subtract): New function, to help XTflash.
	(x_invert_frame): Removed.  This didn't work anyway.
	(XTring_bell): Remove "#if 0" around call to XTflash, and remove
	calls to x_invert_frame.  If both HAVE_TIMEVAL and HAVE_SELECT
	aren't defined, then just do the ordinary beep.

	* window.c (Fscroll_other_window): Prefer windows on the selected
	frame, then look for windows on other visible frames.

	* keyboard.c (Fmouse_click_p): Removed; with the 'e' spec, this
	isn't necessary anymore.
	(syms_of_keyboard): Remove defsubr for it.
	* keyboard.h (Fmouse_click_p): Remove extern declaration for it.

	* xfns.c (gray_bits): Remove this declaration; the same data is in
	<X11/bitmaps/gray>.  #include that instead.
	[not HAVE_X11] (x_set_border_pixel): Use gray_width and
	gray_height, instead of assuming that the bitmap is 16x16.
	(x_make_gc): Instead of creating a pixmap and then calling
	XPutImage to make it into a grey stipple, just call
	XCreatePixmapFromBitmapData to do it all at once.

	* xterm.c (x_text_icon): Move the request for font information
	into the "not HAVE_X11" part of the function; the X11 code doesn't
	need this.

	* xterm.c (x_wm_set_icon_pixmap): Instead of setting the
	icon_pixmap to None, just remove IconPixmapHint from the flags of
	the XWMHints structure.

	* window.c (Fprevious_frame): Use prev_frame when we get to the
	end of the current frame, not next_frame.  Doc fix.
	* frame.c (prev_frame): Remove "#if 0" from this function.  It
	turns out we do need it, to make prev_frame work right.

	* frame.c (next_frame): Check that FRAME is a live frame.

	* frame.c (Fselect_frame): Remove "#ifdef MULTI_FRAME" clause
	around the code which calls Ffocus_frame; this code is already
	inside an "#ifdef MULTI_FRAME" clause.
	(next_frame, prev_frame, Fnext_frame): For the same reasons,
	remove the "#ifdef MULTI_FRAME" clause around these functions.

	unread-command-event has been replaced by unread-command-events.
	* commands.h (unread_command_event): Change extern declaration.

	quit_throw_to_read_char, init_keyboard): Change to use
	unread_command_events, with the new semantics.
	* lread.c (read_char): Same.
	* minibuf.c (temp_echo_area_glyphs): Same.
	* xterm.c (unread_command_event): Remove external declaration for
	this; it is only used by obsolete code.

	* Makefile.in: Some makes can't handle comments in the middle of
	commands; move them to before the whole rule.

1993-01-21  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* keyboard.c (make_lispy_event): When handling a mouse click event
	on a window, change x and y from screen coordinates to window
	coordinates even when the click isn't in the text area.

	* xterm.c (x_scrollbar_create): Remove code which asks for
	EastGravity for windows; Emacs can't correctly deal with them
	moving around unexpectedly.

	* xterm.c (XTread_socket): Minor reformatting.

	* xterm.c (x_set_window_size): Always mark the frame garbaged.

        * window.c (Vmouse_window): Variable removed; it can't be handled
	properly without race conditions, and the events give you all the
	information you need anyway.
	(syms_of_window): Remove DEFVAR.
	* callint.c (Fcall_interactively): Change the `@' spec to select
	the window of the first parameterized event in the key sequence
	which invoked the command, instead of using Vmouse_window, which
	isn't even updated anymore.  Adjust the documentation
	accordingly.

1993-01-20  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xterm.c (x_scrollbar_create): Set the scrollbars to use
	EastGravity.

	* keyboard.c (make_lispy_event): Deal with button releases with no
	stored down-going position.  Make sure we always store a Qnil in
	the right button_down_location element after using it.

1993-01-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* frame.c (Fdelete_frame): Clear the frame's display after calling
	the window-system-dependent frame destruction routine.  We
	no longer need to pass the display as a separate argument to
	x_destroy_window.
	* xterm.c (x_destroy_window): Put the code which clears out f's
	display here, right after we free the storage it points to.  Put
	everything, including the code which clears x_focus_frame and
	x_highlight_frame, inside the BLOCK/UNBLOCK_INPUT pair.

	* dispnew.c (Fredraw_display): Undo change of Jan 12; redraw only
	frames whose garbaged flag is set.  The change to
	FRAME_SAMPLE_VISIBILITY on Jan 14 should address the problem better.

	keyboard.c (read_char_menu_prompt): Test HAVE_X_WINDOWS, not
	HAVE_X_WINDOW.

	The CPP symbol indicating whether or not we have mouse menu
	support under X Windows is HAVE_X_MENU, not not NO_X_MENU.
	* emacs.c (main): Test HAVE_X_MENU, instead of NO_X_MENU.
	* keyboard.c (read_char_menu_prompt): Same.
	* ymakefile: Same.

	* keyboard.c (read_char, read_char_menu_prompt): Use the
	EVENT_HAS_PARAMETERS macro from keyboard.h, instead of writing it
	out.

	* keyboard.c (read_char_menu_prompt): Doc fix.

	* keyboard.c (read_char_menu_prompt): Fix test for no menus;
	comparing name to Qnil doesn't work if we are called with no maps.

	* keymap.c (Fdefine_key): Call Fkey_description to make the string
	to use in the error message.

1993-01-18  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* window.c (Fdisplay_buffer): Doc fix.

1993-01-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xterm.c (x_window_to_scrollbar): Search frames'
	condemned_scrollbars list as well; input might arrive during
	redisplay.
	(x_scrollbar_report_motion): Don't forget to BLOCK_INPUT.
	(XTjudge_scrollbars): Clear the condemned scrollbar list before
	traversing it, so we don't try to process an event on a scrollbar
	we've killed.

1993-01-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (Frecent_keys): Doc fix.

1993-01-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* window.c (Fwindow_at): Doc fix.

1993-01-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* xterm.c (x_scrollbar_create): Include PointerMotionHintMask in
	the event mask for scrollbars.

	* dispnew.c (Fredraw_display): DEFUN was missing a closing paren.

	* term.c (set_vertical_scrollbar_hook, condemn_scrollbars_hook,
	redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo
	"externs" from these.  They're supposed to be real definitions.

	* .gdbinit: Add "-geometry +0+0" to default args.
	(xscrollbar): New command.

	Make scrollbar structures into lisp objects, so that they can be
	GC'd; this allows windows and scrollbars can refer to each other
	without worrying about dangling pointers.
	* xterm.h (struct x_display): vertical_scrollbars and
	judge_timestamp members deleted.
	(struct scrollbar): Redesigned to be a template for a Lisp_Vector.
	(SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
	SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
	VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
	VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
	New macros, to help deal with the lispy structures, and deal with
	the graphics.
	* frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
	(struct frame): New fields `scrollbars' and
	`condemned_scrollbars', for use by the scrollbar implementation.
	[MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
	FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
	* window.h (struct window): Doc fix for vertical_scrollbar field.
	* frame.c (make_frame): Initialize the `scrollbars' and
	`condemned_scrollbars' fields of the new frame.
	* alloc.c (mark_object): Mark the `scrollbars' and
	`condemned_scrollbars' slots of frames.
	* xterm.c (x_window_to_scrollbar): Scrollbars are chained on
	frames' scrollbar field, not their x.display->vertical_scrollbars
	field.
	(x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
	x_scrollbar_remove, XTset_vertical_scrollbar,
	XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
	x_scrollbar_expose, x_scrollbar_handle_click,
	x_scrollbar_handle_motion): Substantially rewritten to correct
	typos and brainos, and to accomodate the lispy structures.

	* xterm.c (x_scrollbar_background_expose): Function deleted; we
	don't want anything in the background there after all.
	(XTread_socket): Don't call x_scrollbar_background_expose.  We
	don't care.

	* frame.h (FRAME_SAMPLE_VISIBILITY): Make sure frame is marked as
	garbaged whenever it goes from invisible to visible.
	* dispextern.h (frame_garbaged): Move extern declaration from here...
	* frame.h (frame_garbaged): ... to here.  The FRAME_SAMPLE_VISIBILITY
	macro uses it now, and this seems to be just as modular.  Make a
	new page, just for this and message_buf_print.
	(struct frame): Doc fix for the `visible' field.
	* process.c: #include "frame.h" instead of "dispextern.h"; the
	only thing we care about from it is the frame_garbaged
	declaration.
	* ymakefile: Note dependency change.

	* xfns.c (Fx_create_frame): After mapping the frame, call
	SET_FRAME_GARBAGED, not just plain FRAME_GARBAGED.

	* window.c (window_internal_width): New function, which accounts
	for scrollbars if present.
	* lisp.h (window_internal_height, window_internal_width): Add
	extern declarations for these.
	* dispnew.c (direct_output_for_insert, direct_output_forward_char,
	buffer_posn_from_coords): Use window_internal_width instead of
	writing out its definition.
	* indent.c (compute_motion): Doc fix; mention scrollbars and
	window_internal_width.
	(pos_tab_offset, Fvertical_motion): Use window_internal_width
	instead of writing it out.
	* window.c (Fpos_visible_in_window_p, Fwindow_width, Fscroll_left,
	Fscroll_right): Same.
	* xdisp.c (redisplay, try_window, try_window_id,
	display_text_line): Same.

	* xdisp.c (display_string): Add new variable `f', to be W's
	frame.  Use it to set desired_glyphs, and to get the frame's width
	to decide whether or not to draw vertical bars.

	* xdisp.c (display_text_line): If we're using vertical scrollbars,
	don't draw the vertical bars separating side-by-side windows.
	(display_string): Same thing.  Draw spaces to fill in the part of
	the mode line that is under the scrollbar in partial-width
	windows.

	* xfns.c (Qvertical_scrollbars): New symbol.  Use it as the name
	of the parameter which decides whether or not the frame has
	scrollbars, instead of Qvertical_scrollbar.
	(Fx_create_frame): Adjusted accordingly.
	(syms_of_xfns): Initialize and staticpro Qvertical_scrollbars.
	(x_set_vertical_scrollbar): Renamed to x_set_vertical_scrollbars.
	(x_frame_parms): Adjusted accordingly.

	* xterm.h (CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT,
	PIXEL_TO_CHAR_WIDTH, PIXEL_TO_CHAR_HEIGHT): Rewritten, using:
	(CHAR_TO_PIXEL_ROW, CHAR_TO_PIXEL_COL, PIXEL_TO_CHAR_ROW,
	PIXEL_TO_CHAR_COL): New macros.
	* xfns.c [not HAVE_X11] (Fx_create_frame): Use the
	PIXEL_TO_CHAR_{HEIGHT,WIDTH} macros to figure the frame's
	character size, and the CHAR_TO_PIXEL* macros for vice versa.
	* xterm.c (XTwrite_glyphs, XTclear_end_of_line, stufflines,
	scraplines, dumprectangle, pixel_to_glyph_coords, x_draw_box,
	clear_cursor, x_display_bar_cursor, x_draw_single_glyph,
	x_set_mouse_position): Use the CHAR_TO_PIXEL_* macros.

	* xterm.c (x_wm_set_size_hint): The max_width and max_height
	members of the size_hints are expressed in pixels, not columns.

	* xterm.c (x_set_window_size): Remove ibw var; it's not used.
	Set FRAME_WIDTH (f) to cols instead of rows.  Duh.

	* xterm.c (pixel_to_glyph_coords): Properly set *bounds to the
	character cell bounding the position, even when the position is
	off the frame.

	* xfns.c (x_set_name): To request that the modelines be redrawn,
	execute the statement "update_mode_lines = 1;" instead of the
	silly statement "update_mode_lines;".

	* xfns.c (x_set_vertical_scrollbars): Don't try to set the
	X window's size if the frame's X window hasn't been created yet.

	* xfns.c (x_figure_window_size): Set the frame's
	vertical_scrollbar_extra field before trying to calculate its
	pixel dimensions.

	* xfns.c (x_window): When calling x_implicitly_set_name for the
	sake of drawing the name for the first time, remember to clear and
	set the frame's explicit_name member as well as its name member.
	(Fx_create_frame): Set the frame's explicit_name member if the
	user specified the name explicitly.

	* xdisp.c (display_text_line): Use the usable internal width of
	the window, as calculated above, as the limit on the length of the
	overlay arrow's image, rather than using the window's width field,
	less one.

	* xdisp.c (redisplay): Call condemn_scrollbars_hook and
	judge_scrollbars_hook whenever they are set, not just when the
	frame has vertical scrollbars.

	* termhooks.h (mouse_position_hook): Doc fix.
	(set_vertical_scrollbar_hook): This doesn't return anything any
	more, and doesn't take a struct scrollbar * argument any more.
	(condemn_scrollbars_hook, redeem_scrollbar_hook,
	judge_scrollbars_hook): Doc fixes.
	* term.c (mouse_position_hook): Doc fix.
	(set_vertical_scrollbar_hook): This doesn't return
	anything any more.  Doc fixes.
	* keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
	window from *mouse_position_hook and pass it to
	make_lispy_movement, instead of working with a pointer to a struct
	scrollbar.
	(make_lispy_event): We don't need a window_from_scrollbar function
	anymore; we are given the window directly in *EVENT.
	Unify the code which generates
	text-area mouse clicks and scrollbar clicks; use the same code to
	distinguish clicks from drags on the scrollbar as in the text area.
	Distinguish clicks from drags by storing a copy of the lispy
	position list returned as part of the event.
	(button_down_location): Make this a lisp vector, rather than an
	array of random structures.
	(struct mouse_position): Remove this; it's been replaced by a lisp
	list.
	(make_lispy_movement): Accept the scrollbar's window as a
	parameter, rather than the scrollbar itself.
	If FRAME is zero, assume that the other arguments are garbage.
	(syms_of_keyboard): No need to staticpro each window of
	button_down_location now; just initialize and staticpro it.
	* window.c (window_from_scrollbar): Function deleted; no longer
	needed.
	* xdisp.c (redisplay_window): Just pass the window to
	set_vertical_scrollbar hook; don't pass the scrollbar object too.
	* xterm.c (XTmouse_position): Don't return a pointer to the
	scrollbar for scrollbar motion; instead, return the scrollbar's
	window.

	* xterm.c (XTmouse_position): Entirely rewritten, using
	XTranslateCoordinates.  Call x_scrollbar_report_motion to handle
	scrollbar movement events.
	(x_scrollbar_report_motion): New function, to help out
	XTmouse_position.

	* keyboard.c (apply_modifiers): Don't assume that the Qevent_kind
	property of BASE is set when we first create the new modified
	symbol.  Check that the Qevent_kind property is properly set each
	time we return any symbol.

	* termhooks.h (struct input_event): Replace the frame member with
	a Lisp_Object member by the name of frame_or_window.  Doc fixes.
	Remove the scrollbar member; instead, use frame_or_window to hold the
	window whose scrollbar was clicked.
	* keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event,
	make_lispy_event): Adjust references to frame member of struct
	input_event to use frame_or_window now.
	* xterm.c (construct_mouse_click, XTread_socket): Same.

	* xterm.c (last_mouse_bar, last_mouse_bar_frame, last_mouse_part,
	last_mouse_scroll_range_start, last_mouse_scroll_range_end):
	Replaced with...
	(last_mouse_scrollbar): New variable.
	(note_mouse_movement): Clear last_mouse_scrollbar when we have
	receieved a new motion.
	(syms_of_xterm): Staticpro last_mouse_scrollbar.

	* xterm.c (note_mouse_position): Renamed to note_mouse_movement,
	because that's what it really does.
	(x_scrollbar_handle_motion): Renamed to x_scrollbar_note_movement,
	for consistency.
	(XTread_socket): Adjusted.

	* xterm.c (XTset_scrollbar): Renamed to XTset_vertical_scrollbar.
	(x_term_init): Adjusted.

	* keyboard.c (kbd_buffer_frames): Renamed to
	kbd_buffer_frame_or_window, and made to exist even when
	MULTI_FRAME isn't defined; single-frame systems might have
	scrollbars.  Use it to GCPRO the frame_or_window field in the
	event queue.
	(kbd_buffer_store_event, kbd_buffer_get_event,
	stuff_buffered_input): Set and clear the
	appropriate element of kbd_buffer_frame_or_window, whether or not
	MULTI_FRAME is #defined.
	(read_avail_input): When reading characters directly from stdin,
	set the frame_or_window field of the event appropriately,
	depending on whether or not MULTI_FRAME is #defined.
	(Fdiscard_input, init_keyboard): Zap kbd_buffer_frame_or_window,
	not kbd_buffer_frames.
	(syms_of_keyboard): Initialize and staticpro
	kbd_buffer_frame_or_window, whether or not MULTI_FRAME is
	#defined.

	* keyboard.c (head_table): Make Qscrollbar_movement have a
	Qevent_kind property of Qmouse_movement, not Qscrollbar_movement.

	* keyboard.c (read_key_sequence): If we decide to throw away a
	mouse event which has prefix symbols (`mode-line',
	`vertical-scrollbar', etcetera), remember that we may have to
	unwind two characters, not just one.

	* keyboard.c (read_key_sequence): Doc fixes.

	* keyboard.c (kbd_buffer_store_event): Fix reversed sense of test
	for focus redirection.

	* keyboard.c (read_char): Don't echo mouse movements.

	* emacs.c (shut_down_emacs): New function.
	(fatal_error_signal, Fkill_emacs): Call it, instead of writing it out.
	* xterm.c (x_connection_closed): Call shut_down_emacs instead of
	Fkill_emacs; the latter will try to perform operations on the X
	server and die a horrible death.
	* lisp.h (shut_down_emacs): Add extern declaration for it.

	* xterm.c (x_error_quitter): Move the abort call to after we print
	the error message.  No harm in that.

	* xdisp.c (echo_area_display): Move the assignment of f and the
	check for visibility out of the "#ifdef MULTI_FRAME" clause; they
	should work under any circumstances.

	* xdisp.c (redisplay_window): If we're not going to redisplay this
	window because it's a minibuffer whose contents have already been
	updated, go ahead and jump to the scrollbar refreshing code
	anyway; they still need to be updated.  Initialize opoint, so it's
	known to be valid when we jump.  Calculate the scrollbar settings
	properly for minibuffers, no matter what they are displaying at
	the time.

	* xdisp.c (redisplay_windows): Don't restore the current buffer
	and its point before refreshing the scrollbars; we need the buffer
	accurate.

	XPROP.  Pass it along to x_get_arg.
	(Fx_create_frame): Pass new args to x_get_arg and
	x_default_parameter.

	* xfns.c (Fx_create_frame): Use the same resource names and
	classes as xterm and Emacs 18.

	* xfns.c (Fx_get_resource): Use EMACS_CLASS to make class_key
	even if SUBCLASS is specified.  I don't know whether that is
	right, but that's what the doc says.
	Cosmetic changes in arg names and doc string.

1992-12-29  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

	* ralloc.c: [! emacs] [HAVE_CONFIG_H]: #include "config.h"

	* xterm.c (x_focus_event_frame): New variable.
	(XTread_socket): When we receive a FocusIn event that's not
	NotifyPointer, record the frame in x_focus_event_frame.  When we

	have focus.

	* xterm.c (XTread_socket): Remove special code in EnterNotify case
	to handle scrollbars and fake mouse motion events.

	* frame.h (focus_frame): Doc fix.
	[not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
	indicates no focus redirection, instead of zero, which is
	selected_frame.
	* frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
	than making it point to frame itself.
	(Fselect_frame): If changing the selected frame from FOO to BAR,
	make all redirections to FOO shift to BAR as well.  Doc fix.
	(Fredirect_frame_focus): Doc fix.  Accept nil as a valid
	redirection, not just as a default for FRAME.
	(Fframe_focus): Doc fix.
	* keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event): Deal
	with focus redirections being nil.
	* xterm.c (XTframe_rehighlight): Doc fix.  Deal with focus
	redirections being nil.

	* window.c (Fset_window_configuration): Don't restore the frame's
	focus redirection if the target frame is now dead.

	* ymakefile (ralloc.o): This no longer depends on xterm.h.

	* ymakefile (all, xemacs): We build an executable called `emacs' now,
	not `xemacs'.
	* Makefile.in (distclean, xemacs, doxemacs): Same.

	* xterm.h (PIXEL_WIDTH, PIXEL_HEIGHT): Change name of parameter
	from `s' to `f'; it's a frame pointer.

1992-12-18  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* keyboard.c (kbd_buffer_frames): New vector, to GCPRO frames in
	kbd_buffer.
	(kbd_buffer_store_event): When we add an event to kbd_buffer, make
	sure to store its frame in kbd_buffer_frames.
	(kbd_buffer_get_event): When we remove an event from kbd_buffer,
	make sure to set the corresponding element of kbd_buffer_frames to
	Qnil, to allow the frame to get GC'd.
	(Fdiscard_input, init_keyboard): Clear all elements of
	kbd_buffer_frames to nil.
	(syms_of_keyboard): Create and staticpro kbd_buffer_frames.

	* xterm.c (x_error_quitter): Just abort, so we can look at the
	core to see what happened.

1992-12-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* buffer.c (Frename_buffer): Set update_mode_lines.

1992-12-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* scroll.c (do_scrolling): When bcopying the max_ascent field from
	current_frame to temp_frame, remember that max_ascent is an array
	of shorts, not ints.

	It's a pain to remember that you can't assign to FRAME->visible.
	Let's change all references to the `visible' member of struct
	frame to use the accessor macros, and then write a setter for the
	`visible' field that does the right thing.
	* frame.h (FRAME_VISIBLE_P): Make this not an l-value.
	(FRAME_SET_VISIBLE): New macro.
	* frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE.
	(Fframe_visible_p, Fvisible_frame_list): Use FRAME_VISIBLE_P and
	FRAME_ICONIFIED_P.
	* dispnew.c (Fredraw_display): Use the FRAME_VISIBLE_P and
	FRAME_GARBAGED_P accessors.
	* xdisp.c (redisplay): Use the FRAME_VISIBLE_P accessor.
	* xfns.c (x_set_foreground_color, x_set_background_color,
	x_set_cursor_color, x_set_border_pixel, x_set_icon_type): Use the
	FRAME_VISIBLE_P accessor.
	(Fx_create_frame): Use FRAME_SET_VISIBILITY.
	* xterm.c (clear_cursor, x_display_bar_cursor,
	x_display_box_cursor): Use FRAME_SET_VISIBILITY.

1992-12-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* ymakefile (CFLAGS): #define HAVE_CONFIG_H too.

	* Makefile.in (distclean): Don't delete machine.h or system.h;
	they don't exist anymore.

	* Makefile.in (distclean): Don't delete autosave or backup files.
	(extraclean): New target; like distclean, but delete autosave
	and backup files too.

1992-12-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* search.c (Fskip_chars_forward, Fskip_chars_backward): Return the
	distance traveled.
	(skip_chars): Return the distance traveled, as a Lisp_Object.

	* macros.c (Fend_kbd_macro): Don't use XFASTINT to check if arg is
	negative; XFASTINT only works on values known to be positive.
	(Fexecute_kbd_macro): Check QUIT in the repetition loop.  If the
	macro is null, no characters are actually being read, so this
	matters.

	* Makefile.in (srcdir): New variable, not fully implemented.
	(xmakefile): Turn -g and -O in CFLAGS into C_DEBUG_SWITCH and
	C_OPTIMIZE_SWITCH in C_SWITCH_SITE's definition.  Delete junk.cpp
	when done.
	* ymakefile (archlib): Variable definition deleted.  Run programs
	from ../lib-src directly, or use ${archlibdir}.
	(${etc}DOC): Run make-docfile from ${libsrc}, not ${archlib}.
	(${archlib}make-docfile, ${archlib}emacstool): Use ${libsrc}, not
	${archlib}.

	* ymakefile (lisp): Don't include version.el in this list.

	Give subprocess creation a way to find a valid current directory
	for subprocesses when the buffer's default-directory is a handled
	name.
	* fileio.c (Funhandled_file_name_directory): New function.
	(Qunhandled_file_name_directory): New file-name-handler operation.
	(syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
	initialize and staticpro Qunhandled_file_name_directory.
	* callproc.c (Fcall_process): Call Funhandled_file_name_directory
	on the buffer's default directory.  Do it earlier in the function
	so there's less to GCPRO.
	* process.c (create_process): Don't check the validity of the
	buffer's default directory here...
	(Fstart_process): Instead, do it here; if we call
	Funhandled_file_name_directory here, there's less GCPROing to do.

	* callproc.c (Fcall_process_region): Return the value returned by
	Fcall_process.

	* fileio.c (find_file_handler): Rename this to
	Ffind_file_name_handler, and make it visible to lisp.  Add a QUIT
	to the loop which scans file-name-handler-alist.  All uses
	changed.
	(syms_of_fileio): Mention this new function in the docstring for
	Vfile_name_handler_alist.  defsubr Sfind_file_name_handler.
	* lisp.h (Ffind_file_name_handler): Added extern declaration.
	* dired.c: All uses of find_file_handler changed here too.

	* fileio.c (syms_of_fileio): Add staticpros for Qexpand_file_name,
	Qdirectory_file_name, Qfile_name_directory,
	Qfile_name_nondirectory, Qfile_name_as_directory.

1992-12-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* window.c (Fset_window_configuration): If we're restoring the
	configuration of a dead frame, don't bother rebuilding its window
	tree, restoring its focus redirection, or temporarily resizing it
	to fit the saved window configuration.  If the frame which was
	selected when the configuration was captured is now dead, don't
	try to select it.

	* frame.c (Fdelete_frame): Delete all the windows in the frame's
	window tree, using delete_all_subwindows.
	* window.c (delete_all_subwindows): Don't make this static
	anymore.

1992-12-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	Make sure that frames' visible flag only changes at acceptable
	times.  See FRAME_SAMPLE_VISIBILITY's comments for details.
	* frame.h (struct frame): New fields called async_visible and
	async_iconified.
	(FRAME_SAMPLE_VISIBILITY): New macro, with MULTI_FRAME and
	non-MULTI_FRAME definitions.
	* xdisp.c (redisplay): Call FRAME_SAMPLE_VISIBILITY to set the
	visible and iconified flags appropriately for each frame.
	(message1): Call FRAME_SAMPLE_VISIBILITY to set the visible and
	iconified flags for the minibuffer frame.
	* frame.c (make_frame): Initialize async_visible and
	async_iconified properly.
	* xfns.c (Fx_create_frame): Initialize f->async_visible too.
	* xterm.c (XTread_socket): When we get MapNotify, UnmapNotify,
	Expose, ExposeWindow, or UnmapWindow, set f->async_visible, not
	f->visible.
	(x_do_pending_expose, x_raise_frame, x_lower_frame,
	x_make_frame_invisible, x_make_frame_visible, x_iconify_frame):
	Test and set f->async_visible and f->async_iconified, not
	f->visible or f->async_iconified.

	* keyboard.c (kbd_store_ptr): Declare this to be volatile, if
	__STDC__ is #defined.
	(Fdiscard_input): Use cast to keep GCC from complaining about the
	assignment of kbd_store_ptr to kbd_fetch_ptr.

	* xdisp.c (redisplay): Use FOR_EACH_FRAME to apply
	redisplay_windows to the root window of each frame.  This makes a
	#ifdef MULTI_FRAME unneeded, but it also means we recompute
	buffer_shared from scratch even on non-MULTI_FRAME configurations.
	Don't skip elements of Vframe_list that aren't frames; go ahead
	and crash here.

	* xdisp.c (redisplay): Remove #ifdef MULTI_FRAME around the code
	which updates separate minibuffer frames specially; there's
	nothing there that won't work on a single-frame configuration.

	* dispextern.h (struct frame_glyphs): Doc fix.

1992-12-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* dispnew.c: Remove dyked-out copy of safe_bcopy.

	* environ.c: File removed; Changes on 1/13/1992 made it
	unnecessary.

1992-12-01  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* process.c (wait_reading_process_input): Doc fix.

1992-11-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	(NeXT): Defined.
	(BIG_ENDIAN): Define only if __BIG_ENDIAN__.
	(m68000, COMPILER_REGISTER_BUG): Defs deleted.
	(SIGN_EXTEND_CHAR, LIB_X11_LIB, NO_T_CHARS_DEFINES, UNEXEC): Defined.
	(LIBS_DEBUG, LIB_GCC, C_SWITCH_MACHINE, ORDINARY_LINK): Defined.
	(TEXT_START, TEXT_END, DATA_END, LD_SWITCH_MACHINE): Defined.
	(KERNEL_FILE): #undef it.
	(environ): Define as _environ.

1992-11-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* doc.c (store_function_docstring): New function, made from part
	of Fsnarf_documentation, which handles docstrings for macros
	properly.
	(Fsnarf_documentation): Call store_function_docstring.

	* data.c (indirect_function): Delete unused argument ERROR.

1992-11-23  Jim Blandy  (jimb@apple-gunkies.gnu.ai.mit.edu)

	* Makefile.in (clean): Remove prefix-args.

1992-11-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s/sol2.h (LD_SWITCH_SYSTEM): Make alternate version for GCC.

1992-11-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* m/sparc.h: Don't include <sys/param.h> here; that screws up the
	xmakefile.  Instead, include it in getloadavg.c, which is the only
	place that uses LOAD_AVE_CVT, which is the only reason
	<sys/param.h> was here in the first place.

1992-11-15  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* dispnew.c [not MULTI_FRAME] (Fredraw_display): Pass the correct
	number of arguments to mark_window_display_accurate.

	* undo.c (Fprimitive_undo): Remove whitespace in front of #ifdef
	and #endif.

	* systty.h: Doc fix.

	* systty.h, process.c, buffer.h, callproc.c, sysdep.c, dired.c:
	Added VMS changes from Roland Roberts.
	* vmspaths.h: New version from Roland Roberts.

	* xdisp.c (display_string): Use w's buffer's value of
	tab-width to display the string, instead of the current buffer's,
	which could be anything.

	* s/sol2.h (LD_SWITCH_SYSTEM): Add -R option.

	* process.c (read_process_output): Save, widen, insert the process
	output, and then restore the restriction if inserting text outside
	the visible region.

1992-11-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* buffer.c (Ferase_buffer): Doc fix.

	* dispnew.c (safe_bcopy): Use the right terminating condition in
	the loop which uses multiple bcopy calls to transfer a block to an
	overlapping higher block.

1992-11-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* process.c (Fstart_process): Establish an unwind-protect to
	remove PROC from the process list if an error occurs while
	starting it.
	(start_process_unwind): New function to help with that.
	(create_process): There's no need to explicitly call
	remove_process if the fork fails; the record_unwind_protect in
	Fstart_process will take care of it.

	* commands.h (unread_command_event): Doc fix.

	Don't ever throw away switch-frame events.
	* lread.c: #include "keyboard.h".
	(Fread_char, Fread_char_exclusive): Don't signal an
	error for or throw away switch-frame events; instead, put them off
	until after we've found a character we can respond to.
	* commands.h (unread_switch_frame): Declare this extern.
	* keyboard.c (unread_switch_frame): Don't declare this static.
	* ymakefile (lread.o): Note that this depends on keyboard.h.

	* keyboard.c (Vlast_event_frame): Doc fix.

	* process.c (wait_reading_process_input): Test the C preprocessor
	symbol "ultrix", not "__ultrix__" to see if we should ignore
	ENOMEM errors from select.

	* fileio.c (Fexpand_file_name): Don't fiddle with "/." if it's the
	entire string.

	* buffer.c (Fbury_buffer): Make this behave as in 18.59, although
	that behavior is very odd - only remove the buffer from the
	selected window if BUFFER was nil or omitted.

	* keyboard.c (read_char): Write composite events to the dribble
	file properly.

	* keyboard.c (init_keyboard): Initialize Vlast_event_frame to
	Qnil, rather than the selected frame.

	* mem-limits.h [DATA_SEG_BITS] (EXCEEDS_LISP_PTR): Remember to
	remove DATA_SEG_BITS from the pointer before testing if the
	pointer fits in VALBITS.

	* Makefile.in (doxemacs, dotemacs): Explicitly pass along the CC
	variable in these rules, just as in the `doall' rule.

	* ralloc.c (relocate_some_blocs): Handle BLOC == NIL_BLOC.
	(free_bloc): This can now be simplified.

	* ralloc.c (r_alloc_sbrk): When we allocate new space for the
	malloc heap, zero it out even if we don't have any blocs in the
	free list.

1992-11-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* process.c (process_send_signal): On systems which have both
	the TIOCGETC and TCGETA ioctls, just use the former.

	* xselect.c (Fx_get_cut_buffer): Correct check for buf_num in
	range.

	* xselect.c (Fx_get_cut_buffer, Fx_set_cut_buffer): Fix error
	message format; use NUM_CUT_BUFFERS instead of literal 7.

	* keyboard.c (lispy_modifier_list): Added sanity check before
	indexing into modifier_symbols.

	* keyboard.c (add_command_key): When copying the contents of the
	old this_command_keys to new_keys, remember to multiply size by
	sizeof (Lisp_Object) to get the amount we really need to copy.

	Rename unread_command_char to unread_command_event; it has
	subtly different semantics now, and we should use
	`make-obsolete-variable' to warn people.
	* command.h (unread_command_char): Change name in extern declaration.
	* keyboard.c (unread_command_char): Rename.
	(command_loop_1, read_char, Finput_pending, Fdiscard_input,

	to unread_command_event.

1992-11-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* m/pmax.h: Don't define SYSTEM_MALLOC; this was only necessary
	for Ultrix version 4.1, and the current version is 4.3.

	* s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
	* process.c (process_send_signal): Put all the code for sending
	signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS.  Decide
	whether to use the Berkeley-style or SYSV-style ioctls by seeing
	which ioctl commands are #defined.

	* minibuf.c (read_minibuf): If get_minibuffer gives the
	new minibuffer a nil default directory, find another buffer with a
	better default directory and use that one's instead.

1992-11-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* process.c (process_send_signal): Doc fix.

	* keyboard.c (read_key_sequence): Don't use
	save_excursion_{save,restore} to protect the caller against buffer
	switches; use Fset_buffer and Fcurrent_buffer; redisplay might
	change point, and we don't want to undo that.

	* keyboard.c (kbd_buffer_get_event): When checking a mouse
	movement for a frame switch, don't assume Vlast_event_frame
	contains a Lisp_Frame object.

1992-11-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s/dgux.h (SYSTEM_TYPE): Use berkeley-unix.

1992-11-04  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* alloc.c: #include "frame.h" unconditionally.  frame.h does the
	right thing when MULTI_FRAME isn't defined.

	* Makefile.in: Rearrange dependencies to make sure that xmakefile
	is built before we try to use it, even using a parallel make.

	Changes for SYSV from Eric Raymond:
	* process.c [SYSV]: Don't include <termios.h>, <termio.h>, or
	<fcntl.h>.
	(process_send_signal): Don't try to send SIGTSTP
	unless SIGTSTP is defined.
	* sysdep.c (init_baud_rate) [HAVE_TERMIO, not HAVE_TCATTR]: Use
	TCGETA, not TIOCGETP.
	* systime.h [USG] (EMACS_GET_TZ_OFFSET): Assign to *(offset), not
	(offset).  Don't forget the while corresponding to the do.
	Include USG in the list of systems that have a tzname array.

	* keyboard.c (read_key_sequence): Removed the
	replay_sequence_new_buffer label; replay_sequence should be here
	instead.

	Arrange to get compile-time errors for uses of Lisp_Frame in a
	non-MULTI_FRAME configuration.
	* lisp.h [not MULTI_FRAME]: Don't declare the Lisp_Frame tag.
	* minibuf.c (read_minibuf): Protect call to Fredirect_frame_focus
	with a #ifdef MULTI_FRAME.
	* window.c (Fset_window_configuration): Protect call to
	Fselect_frame with a #ifdef MULTI_FRAME.
	[not MULTI_FRAME] (Fcurrent_window_configuration): Don't bother
	setting the window configuration's selected_frame member.
	* keyboard.c (Vlast_event_frame): Arrange for this to exist iff
	MULTI_FRAME is defined.
	[not MULTI_FRAME] (syms_of_keyboard): Don't DEFVAR Vlast_event_frame.
	[not MULTI_FRAME] (read_char): Don't try to set Vlast_event_frame.
	[not MULTI_FRAME] (kbd_buffer_store_event): Don't try to set
	Vlast_event_frame for quit characters.
	[not MULTI_FRAME] (kbd_buffer_get_event): Don't try to generate
	switch-frame events.

	* buffer.c (init_buffer): If PWD is accurate, use it instead of
	calling getwd.
	#include <sys/types.h> and <sys/stat.h>, for the call to stat.

        Indicate whether an autoload form stands for a keymap or not.
	* eval.c (Fautoload): Renamed fifth argument TYPE.  Document the
	fact that (eq TYPE 'keymap) means FUNCTION will become a keymap
	when loaded.
	(Fmacroexpand): Instead of assuming that every autoload
	form with a fifth element is a macro, actually check the fifth
	element against t and `macro', which are the only values which
	denote macroness.
	* keymap.c (get_keymap_1): Don't try to autoload OBJECT's function
	unless the autoload form indicates that it's a keymap.

1992-11-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	* .gdbinit (mips): New command.

1992-10-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c (Fmake_directory_internal): Renamed from Fmake_directory.
	Pass nil as third arg to handler.
	Lisp function `make-directory' is now in files.el.

1992-10-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

	Clean up errors due to treating Lisp_Objects like integers.
	* abbrev.c (Funexpand_abbrev): Just assign the last abbrev's value
	to val; don't use XSET.  Make sure that the value of the
	abbrev-symbol is a string.
	* alloc.c (Frope_elt): Declare arguments to be Lisp_Objects.
	* buffer.c (reset_buffer): Don't assign to b->save_length as if it
	were an int; use XFASTINT.

	declarations.
	* bytecode.c (Fbyte_code): Use EQ to compare string_saved with
	bytestr.
	* casefiddle.c (operate_on_word): Declare end to be an int, not a
	Lisp_Object.
	* casetab.c (set_case_table): Declare this to be static, and
	return a Lisp_Object. Add static declaration for this
	before Fset_case_table and Fset_standard_case_table.
	(Fset_case_table, Fset_standard_case_table): Return the return
	value of set_case_table, instead of returning garbage.
	* commands.h (unread_command_char): Declare this to be a
	Lisp_Object, not an int.
	* data.c (Fset): See if current_alist_element points to itself
	using EQ, not ==.
	(float_arith_driver): Declare this extern above arith_driver.
	* dired.c (find_file_handler): Declare this extern.
	(Ffile_attributes): Use NILP, not == Qnil.
	* dispextern.h (sit_for): Declare this extern.
	* doc.c: #include keyboard.h.
	* floatfns.c (Flog): Don't forget to declare the BASE argument a
	Lisp_Object.
	* fns.c: #include keyboard.h.
	(Fdelete): Check if Fequal returns Qnil, not zero.
	* frame.c: #include buffer.h.
	* keyboard.c: #include dispextern.h.
	(recursive_edit_unwind, command_loop, Fthis_command_keys): Declare
	these to return Lisp_Objects at the very top of the file, to avoid
	having them implicitly declared as ints.
	(echo_char): Use EQ to compare C to help_char.
	(read_char): Remember to apply XFASTINT to the return value of
	Flength before using it.  Apply XINT to c when clearing its high
	bits and meta bits, and when writing it to the dribble file.
	(read_char_menu_prompt): Use EQ to compare obj with
	menu_prompt_more_char and its control-character analog.
	(read_key_sequence): Declare PROMPT to be char *, not a
	Lisp_Object.  Use the appropriate accessors on keybuf when looking
	for ASCII function key sequences.
	* keyboard.h (get_keymap_1, Fkeymapp, reorder_modifiers,
	Fmouse_click_p, read_char): Add external declarations for these.
	* keymap.c (Fdefine_key, Flookup_key, describe_map): Don't assume
	that Flength returns an integer.
	* lisp.h (Fdefault_boundp, make_float, Ffloat, Fnth, Fcopy_alist,
	Fmake_byte_code, Fverify_visited_file_modtime, Ffile_exists_p,
	Fdirectory_file_name, Ffile_name_directory,
	expand_and_dir_to_file, Ffile_accessible_directory_p, Fbyte_code,
	Fundo_boundary, truncate_undo_list): Add extern declarations for
	these.
	* lread.c (read_char): Add an extern declaration for this,
	indicating that it returns a Lisp_Object.
	* minibuf.c (read_minibuf): Use EQ to compare, not ==.
	(temp_echo_area_glyphs): Use XFASTINT to assign to
	unread_command_char.
	* print.c (print): Cast the frame's address to an integer before
	passing it to sprintf to form the frame's printed form.
	* process.c: (status_convert): Declare this to return a
	Lisp_Object at the top of the file.
	(decode_status): Don't untag XCONS (tem)->cdr before storing it in
	tem; tem is a Lisp_Object, too.
	(process_send_signal): Declare this to be static void.  Don't

	are ints, not Lisp_Objects, and that RESULT->x and RESULT->y are
	Lisp_Objects, not ints.

	a mouse click, read the key sequence using the keymaps of the
	buffer clicked on, not the current buffer.

	* keyboard.c (follow_key): Ask get_keymap_1 to perform autoloads.
	(read_key_sequence): When pursuing potential bindings in the

	perform autoloads.  Autoloading might GC; we need to GCPRO our
	local variables now.
	(Fdocumentation, Fdocumentation_property): Autoloading in

	(Fswitch_to_buffer, Fpop_to_buffer, Fbury_buffer): Likewise.

1992-10-03  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (read_key_sequence): Treat mouse clicks on non-text
	areas as if they were prefixed with the symbol denoting the
	area clicked on - `mode-line', etcetera.
	When we throw away an unbound `down-' event, reset mock_input as
	well.

	* keyboard.c (Qevent_symbol_element_mask, Qmodifier_cache): Two
	new symbols, used to implement caches on event heads.  These take
	the place of some of the caching that modify_event_symbol used to do.
	(parse_modifiers_uncached, apply_modifiers_uncached,
	lispy_modifier_list, parse_modifiers, apply_modifiers): New
	functions, which replace format_modifiers and reorder_modifiers;
	they can be useful elsewhere too.
	(reorder_modifiers, modify_event_symbol): Re-implement these in
	terms of parse_modifiers and apply_modifiers.  modify_event_symbol
	now uses a much simpler cache, and takes advantage of the caches
	maintained by parse_ and apply_modifiers.
	(follow_key): Don't modify NEXT if KEY has no bindings.
	(read_key_sequence): Drop unbound `down-' events, and turn unbound
	`drag-' events into clicks if that would make them bound.  This
	benefits from the rewriting of the modifier key handling code.
	(syms_of_keyboard): Initialize and intern
	Qevent_symbol_element_mask and Qmodifier_cache.

	* keyboard.c (echo_prompt): Terminate the echo buffer properly
	even when the string is too long to display in the minibuffer.
	(echo_truncate): Just return echoptr - echobuf, rather than
	calling strlen on echobuf.

	* alloc.c (Fmemory_limit): New function.
	(syms_of_alloc): Defsubr it.

	* window.c (SAVE_WINDOW_DATA_SIZE): Define this using sizeof,
	instead of just saying it's 7; that way, we won't get screwed if
	we add members to struct save_window_data.

	* window.c (struct save_window_data): Save the currently selected
	frame, too.
	(Fset_window_configuration): Restore the frame's selected window
	using Fselect_window, and then restore the selected frame using
	Fselect_frame.
	(Fcurrent_window_configuration): Record the currently selected
	frame.  Update docstring to describe the information now recorded.

1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* process.c (wait_reading_process_input): Ultrix select seems to
	return ENOMEM when interrupted.  So, under Ultrix, treat ENOMEM
	like EINTR.

	* keyboard.c (modifier_names): The modifier is named "control",
	not "ctrl".

	* keyboard.c (modify_event_symbol): Make sure that the unmodified
	event header gets the proper properties set on it, by recursing
	and letting the same code build the properties for all event symbols.

	* keyboard.c (Qmouse_click): Fix typo which assigned `mouse-click'
	symbol to Qmouse_movement.

1992-10-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* undo.c (Fprimitive_undo):
	When undoing an insert, move point and then delete.

1992-10-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* intervals.c: `copy_intervals' no longer static.

	* intervals.h: Declare `copy_intervals'.

	* buffer.c: #include intervals.h.

	* ymakefile: New macro "INTERVALS", controlled by "USE_INTERVALS",
	which defines the interval include file "intervals.h".
	New entries for "intervals.c" and "textprop.c".

	* lisp.h: Declare Qbuffer_or_string_p.

1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xterm.c (x_find_modifier_meanings): If there are no
	modifiers containing a Meta_ keysym, use the Alt keysyms to
	denote meta.
	(construct_mouse_click): Set the down_modifier bit on mouse
	button press events.
	(XTread_socket): When processing keypress events, use
	x_meta_mod_mask when processing ordinary ASCII characters, not
	just when processing function keys and other non-ASCII events.
	(XTread_socket): If we receive a MappingNotify event with the
	`request' member set to `MappingModifier', then call
	x_find_modifier_meanings to refresh x_meta_mod_mask.

	* window.c (Fset_window_configuration): Clean up the way we save
	and restore the frame's size.

	* termhooks.h (struct input_event): Doc fix.
	(NUM_MOUSE_BUTTONS): New constant.
	(click_modifier): New modifier.
	(NUM_MODIFIER_COMBOS): Removed.

	* keyboard.h (EVENT_HAS_PARAMETERS): Definition changed - all events
	are not 5 elements long.
	(EVENT_HEAD): Work correctly on all sorts of events, not just
	events with parameters.
	(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
	EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
	anymore; this information may appear twice in an event.  These
	are replaced by the POSN_ accessors, which are meant to be
	composed with the EVENT_START and EVENT_END accessors.
	(EVENT_START, EVENT_END): Two new accessors, to get at the
	starting and ending position of an event.
	(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
	POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
	diasassemble the values returned by EVENT_START and EVENT_END.
	* keyboard.c (echo_char, read_char): Apply EVENT_HEAD without first
	testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
	all sorts of events now.
	(read_key_sequence): Use the new accessors to decide in which window
	an event occurred.
	* keymap.c (access_keymap, store_in_keymap,
	Fsingle_key_description): No need to check for
	EVENT_HAS_PARAMETERS before using EVENT_HEAD; the latter now
	works properly on all sorts of events.

	* keyboard.c (Qevent_unmodified): Replaced by...
	(Qevent_symbol_elements): New property.
	(syms_of_keyboard): initialize and staticpro the latter, not the
	former.
	* keyboard.h (Qevent_unmodified): Extern declaration replaced by...
	(Qevent_symbol_elements): This.
	(EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
	property, rather than the Qevent_unmodified property.

	* keyboard.c (readable_events): This doesn't need to scan and
	discard mouse release events anymore; it just uses
	EVENT_QUEUES_EMPTY.
	(kbd_buffer_get_event): No need to skip past mouse release events.

	* keyboard.c (button_down_location): New variable, which
	stores the location at which each button was pressed, so we
	can build a complete drag event when the button is released.
	(make_lispy_event): When a button is pressed, record its
	location in button_down_location, and turn it into a `down'
	event.  When a button is released, compare its release
	location with its press location, and decide whether to call
	it a `click' or `drag' event.
	Change mouse movement events to be arranged like click events.
	(format_modifiers): Note that the click modifier has no
	written representation.
	(modifier_names, modifer_symbols): New variables, used to
	create the Qevent_symbol_elements property.
	(modify_event_symbol): Change the format of the modified
	symbol cache; there are too many modifier bits now to use a
	vector indexed by a modifier mask.  Use an assoc-list instead.
	Document the format of the cache.
	Put the Qevent_symbol_elements property on each new symbol,
	instead of a Qevent_unmodified property.
	(symbols_of_keyboard): Put Qevent_symbol_elements properties on
	the symbols specified in head_table, not Qevent_unmodifed properties.
	Initialize and staticpro modifier_symbols, and staticpro the
	window elements of button_down_location.

	* xmenu.c: #include "keyboard.h".
	(Fx_popup_menu): Use the event accessors defined in keyboard.h,
	instead of writing out cars and cdrs.
	* ymakefile: Note that xmenu.o depends on keyboard.h.

1992-10-02  Joseph Arceneaux  (jla@wookumz.gnu.ai.mit.edu)

	* textprop.c: Conditionalize all functions on
	"USE_TEXT_PROPERTIES".
	* intervals.c: Conditionalize all functions on
	"USE_TEXT_PROPERTIES".
	Removed #include of "screen.h".

	* alloc.c: #include "intervals.h".
	(init_intervals, make_interval,
	mark_interval, mark_interval_tree): New functions conditionally
	defined.
	(make_uninit_string): Call INITIALIZE_INTERVAL.
	(INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
	New macros, conditionally defined.
	(mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
	(gc_sweep): If text properties are in use, place all unmarked
	intervals on the free list.  Call UNMARK_BALANCE_INTERVALS on
	`buffer->intervals' when unmarking `buffer'.
	(compact_strings): Include INTERVAL_PTR_SIZE in calculation for
	target of bcopy when relocating strings.
	(init_alloc_once): Call INIT_INTERVALS.
	(make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
	`size'.
	Moved static declaration of `mark_object' and other functions up
	in the file.

	* fileio.c (Finsert_file_contents): Call offset_intervals if
	text was actually inserted.
	#include "intervals.h".

1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* data.c: Qbuffer_or_string_p added.

	* syntax.c (describe_syntax): Use insert_char to insert `match'.

	* buffer.c (reset_buffer): Do INITIALIZE_INTERVAL on the buffer's
	interval component.
	(Fkill_buffer): Likewise.

	* editfns.c (make_buffer_string): Call copy_intervals_to_string.
	(Finsert_buffer_substring): Call graft_intervals_into_buffer.
	#include "intervals.h".

	* insdel.c: #include "intervals.h"
	(prepare_to_modify_buffer): Call verify_interval_modification.
	(insert_from_string): Call offset_intervals and
	graft_intervals_into_buffer.
	(del_range): Call offset_intervals.
	(insert): Call offset_intervals.

	* emacs.c: #include "intervals.h".
	(main): Call syms_of_textprop.  This is only really present if
	Emacs is compiled with USE_TEXT_PROPERTIES defined.

	* buffer.h: New macro TEMP_SET_PT.  If intervals are used, SET_PT
	and TEMP_SET_PT are function calls.
	Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
	Added DECLARE_INTERVALS to buffer structure to conditionally
	compile an interval tree into it.

	* intervals.h: Declare temp_set_point.

1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* ymakefile (config.h): Doc fix.

1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* config.h.in: Added a slot for definition of USE_TEXT_PROPERTIES,
	controlling compilation of interval code.
	If using GNUC, support inline functions.

	* lisp.h: Conditionally define interval structure and macros.
	Add DECLARE_INTERVALS to struct Lisp_String.

1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* buffer.c (Fother_buffer): Add back the VISIBLE_OK argument.  It
	got removed with no comment or ChangeLog entry, and
	append-to-buffer uses it.

        * window.c (struct save_window_data): Add a member called
	focus_frame, to save and restore the screen's focus frame.
	(Fset_window_configuration): Redirect the frame's focus as
	indicated in the window configuration.
	(Fcurrent_window_configuration): Record the frame's current focus.
	* minibuf.c (read_minibuf): Don't bother to save the current
	frame's focus, and have read_minibuf_unwind restore it; saving and
	restoring the window configurations will take care of that.
	(read_minibuf_unwind): Don't worry about restoring the frame's focus.

	* window.c (Fset_window_configuration): Don't select the frame
	just because we restored its configuration.

	* window.c (Fset_window_configuration): Don't forget to set the
	frame's selected window when we can't call Fselect_window.

	* xterm.c (x_meta_mod_mask): New variable, indicating which X
	modifier bits denote meta keys.
	(x_find_modifier_meanings): New function, to set x_meta_mod_mask.
	(x_convert_modifiers): Use that.
	(x_term_init): Call x_find_modifier_meanings.

	* data.c (Fmake_local_variable): If SYM forwards to a C variable,
	swap in the value for the current buffer immediately.

	* lisp.h: Doc elaboration for Lisp_Buffer_Local_Value.

1992-09-29  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* textprop.c (Ferase_text_properties): Merge intervals when
	possible.

1992-09-29  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xselect.c (Qcut_buffer0): Symbol removed; we're using a new
	interface to the cut buffer now.
	(NUM_CUT_BUFFERS, cut_buffer_atom, cut_buffer_value,
	cut_buffer_cached, cut_buffer_just_set): New variables.
	(Fx_own_selection, Fx_selection_value): Dike out the code to
	handle CUT_BUFFER0 requests.
	(Fx_get_cut_buffer, Fx_set_cut_buffer, x_watch_cut_buffer_cache,
	x_invalidate_cut_buffer_cache): New functions.
	(syms_of_xselect): Don't bother to initialize Qcut_buffer0.
	Initialize and staticpro cut_buffer_value, and defsubr
	Sx_get_cut_buffer and Sx_set_cut_buffer.
	* xterm.c (XTread_socket): Pass PropertyNotify events from the
	root window to x_invalidate_cut_buffer_cache.
	(x_term_init): Call x_watch_cut_buffer_cache here.

	* keymap.c (access_keymap): Don't forget to QUIT while scanning
	the keymap.

	* keyboard.c (recent_keys): This needs to be staticpro'ed.  Change
	it from a C array, which is a pain in the neck to staticpro, into
	a lisp vector, which is easier.
	(read_char, Frecent_keys): Access recent_keys as a lisp vector,
	not a C array.
	(syms_of_keyboard): Set recent_keys to be a vector, and staticpro it.

	* ymakefile (xfns.o): This doesn't depend on xselect.c.

	* xterm.h (ROOT_WINDOW): Use the DefaultScreen macro, not the
	XDefaultScreen function.

	* frame.c (Fdelete_frame): Call Fselect_frame with the appropriate
	number of arguments.

	* data.c (Frem): Use the `fmod' function under SunOS, Ultrix, and
	HP/UX, not just under USG systems.

	* buffer.c (Fbury_buffer): This used to undisplay the buffer being
	buried only if the BUFFER argument was nil.  Instead, undisplay the
	buffer whenever it's displayed in the selected window, no matter
	how it was specified by BUFFER.  This is how it behaves in 18.58,
	and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
	they differ.  Fix the doc string accordingly.

1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* frame.c (Fselect_frame, Fframe_root_window,
	Fframe_selected_window, Fnext_frame, Fmake_frame_visible,
	Fmake_frame_invisible, Ficonify_frame): Doc fixes.

	* ralloc.c: Since the users of the relocating allocation code
	handle memory exhaustion, it's better to return an error code to
	them than to call abort.
	(obtain): If we cannot allocate more memory, don't call
	abort.  Instead, return non-zero iff the allocation is successful.
	(get_more_space): If obtain fails, return zero.
	(get_bloc): Return zero if we can't allocate the new bloc.
	(r_alloc_sbrk): Return zero if we can't allocate more memory.
	(r_alloc): If we can't allocate more memory, set *PTR to zero and
	return zero.
	(r_re_alloc): If we can't allocate more memory, leave *PTR
	unchanged, and return zero.

	* ralloc.c (warnfunction): Renamed to warn_function; users changed.

1992-09-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* insdel.c (del_range): Call record_delete before updating point.

	* fileio.c (Finsert_file_contents): Do record_insert, then inc MODIFF.

	* undo.c (record_delete): Record pos before the deletion.
	(Fprimitive_undo): Go back to recorded position.

1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* window.c (delete_all_subwindows): Save the window's buffer in
	its `height' field; we may need to know the window's old buffer
	once we have restored it from a window configuration.
	(Fset_window_configuration): When we restore a window, if its
	`height' field is a buffer, restore its `buffer' field from that.
	This allows us to leave the window's buffer unchanged if the
	buffer recorded in the configuration is dead.

	* window.c (delete_all_subwindows): Removed unused variable named
	"count".

1992-09-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (read_char): If we're returning an event from a
	macro, set Vlast_event_frame to Qmacro, instead of leaving it set
	to the frame of the previous real event.
	(read_key_sequence): If Vlast_event_frame isn't a frame, don't
	bother switching buffers.
	(syms_of_keyboard): Doc fix for Vlast_event_frame.
	(Vlast_event_frame): Doc fix.

	* termhooks.h (alt_modifier, hyper_modifier, super_modifier,
	down_modifier, drag_modifier): New modifiers, to support the new
	input system.  Re-arranged modifiers so that their bits are in
	canonical order; this makes reorder_modifiers slightly simpler.
	* keyboard.c (format_modifiers, reorder_modifiers): Handle the new
	modifier bits.

	* keymap.c (access_keymap): Remove code to notice bindings for
	Qt.

1992-09-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xmenu.c (single_keymap_panes): Handle vectors properly.

1992-09-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keymap.c (Fwhere_is_internal): Don't forget to advance map to
	the next element when we find something that is neither a vector
	nor a cons.  Don't forget to QUIT in the appropriate places,
	either.

1992-09-23  Joseph Arceneaux  (jla@geech.gnu.ai.mit.edu)

	* textprop.c (Fset_text_properties): Merge adjacent intervals with
	the same properties.
	(Fnext_single_property_change, Fprevious_single_property_change):
	New subrs.

	* intervals.c (merge_interval_left, merge_interval_right): Abort
	if caller tries to merge first (or last, respectively) interval.
	Delete the interval node after merging.
	(copy_intervals): Use `split_interval_right' rather than creating
	new intervals with make_new_interval and attaching them
	explicitly.
	(verify_interval_modification): Changed error message.  GCPRO
	hooks before calling Fnreverse, and correctly Fcdr down the list.
	Also, don't cons multiple copies of the same consecutive
	modification hook.
	(temp_set_point): New function.
	(set_point): Call point-left and point-entered hooks if moving
	between text with different properties.  Use the old and new
	positions as arguments to these calls.

	* intervals.c, intervals.h: (map_intervals, make_buffer_interval,
	 make_string_interval,run_hooks): Deleted.

1992-09-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keymap.c (DENSE_TABLE_SIZE): Doc fix.
	(keymap_table): Function removed; this function exists only to
	support an incorrect understanding of the format of keymaps.
	(access_keymap, store_in_keymap, Fcopy_keymap,
	Faccessible_keymaps): Correctly handle vectors at any point in the
	keymap; don't assume it must be at the front.
	(describe_map): Instead of calling describe_vector on the vector
	in the cadr of the keymap (if present) and then calling
	describe_alist to do the rest, just call describe_map_2.
	(describe_alist): Renamed to describe_map_2; call describe_vector
	when we encounter a vector in the list.
	* xmenu.c (single_keymap_panes): Comment out the code which
	tries to handle a dense keymap's table; it uses keymap_table, and
	the rest of the code never uses the table contents anyway.

	* keymap.c (access_keymap, store_in_keymap): Clarify error message
	for non-ASCII characters.

	* process.c [SIGCHLD && !BSD && !UNIPLUS && !HPUX]
	(create_process): #if 0 out the code which sets the child's
	handler for SIGCHLD to sigchld; the code which gives sigchld its
	value has been diked out under these CPP symbols, so this should
	be diked out too.

	* indent.c (Fmove_to_column): Pass the right number of arguments
	to Findent_to.

1992-09-22  Jim Blandy  (jimb@kropotkin.gnu.ai.mit.edu)

	* emacs.c (emacs_priority): Doc fix.
	(main): Use nice, not setpriority; we just need a
	simple, portable call to nice here.
	* callproc.c (child_setup): Use nice, not setpriority.
	* sysdep.c (sys_suspend): Don't try to use "nice (- nice (0))" to
	set the subshell's priority to normal; nice doesn't return a
	defined value on all systems.  Instead, since emacs_priority gives
	the priority that Emacs was nastied to, we can use it to reset the
	priority in a straightforward way.
	[BSD4_1], [USG], [VMS] (setpriority): Remove dummy and
	compatibility definitions of setpriority.

	* keymap.c (access_keymap): Return the binding of Qt as the
	binding for all unbound characters.

	* fileio.c (syms_of_fileio): Don't try to defsubr Sunix_sync
	unless it's actually been defined - that is, if unix is #defined.

	* xrdb.c (x_get_resource): Cast the value being assigned to
	ret_value->addr, rather than ret_value->addr itself; only GCC
	allows you to cast lvalues.

	* eval.c (unbind_catch): Do the long-jump here.  Take a VALUE
	argument, which specifies the value to return to the catch, or the
	data to give to the condition handler.  Renamed to
	unwind_to_catch, to reflect new role.
	(Fsignal, Fthrow): Removed code to set catch tag value and do the
	long-jump; this is taken care of by unwind_to_catch.

1992-09-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* alloc.c (mark_object): Avoid car recursion on cons with nil in cdr.
	Avoid recursion on constants-vector of a compiled function.

	* oldXMenu: Symlink deleted; anything that uses it needs fixing
	in any case to work properly on systems without symlinks.

1992-09-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s/sol2.h: New file.

	* fileio.c: Don't include sys/dir.h.

	* s/usg5-4.h (LIBS_SYSTEM): Move non-default libraries here.
	(LIB_STANDARD, START_FILES): Deleted.
	(ORDINARY_LINK): Defined.

	* ymakefile [ORDINARY_LINK]: Default LD to $(CC)
	and make START_FILES and LIB_STANDARD empty.
	(C_SWITCH_X_MACHINE, C_SWITCH_X_SYSTEM): New macros, default empty.
	(CFLAGS): Use them.

1992-09-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* ymakefile (${etc}DOC): Use OBJECTS_SYSTEM and OBJECTS_MACHINE.

	* dired.c [VMS]: Include string.h, rms.h, rmsdef.h.
	[VMS] (Ffile_version_limit): New function.

	* sysdep.c (sys_suspend): Read EMACS_PARENT_PID envvar for parent.

	* syntax.c (scan_lists): When searching back for comment:
	if comment-end is 2 chars, assume it does end a comment.
	Otherwise, scan back to previous comment-end to see if there's
	a comment starter between.  Also record whether the string quotes
	between the start and the end are paired and uniform.
	If so, skip to comment starter.  If not, scan from start of
	defun to find comment starter if any.
	(find_defun_start): New function.

	* alloc.c (mark_object): Save last 500 values of objptr.
	Check for clobberage of ptr, when marking a vector.

1992-09-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keymap.c (get_keyelt): Skip menu help string after menu item name.

1992-09-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* buffer.c (Fget_buffer_create): Doc fix.

	* lisp.h (struct handler): Remove the poll_suppress_count member
	of this structure; it is always equal to the poll_suppress_count
	of its catchtag structure.  The non-local exit code in eval.c is
	difficult enough to understand as it is; needless duplication
	doesn't help.
	* eval.c (Fcondition_case): Rearranged for clarity.  Don't worry
	about setting h.poll_suppress_count; it's guaranteed to be the
	same as c.poll_suppress_count.
	(internal_condition_case): Don't worry about
	h.poll_suppress_count.
	(Fsignal): Use h->tag->poll_suppress_count instead of
	h->poll_suppress_count.

	* eval.c (Fsignal): It's okay for the debugger to return to the
	caller if the caller was signalling a quit.

	* eval.c (unbind_catch): Restore the polling suppression count
	here, instead of in Fsignal and Fthrow.
	(Fthrow, Fsignal): Don't restore the polling suppression count here.

	* lisp.h (struct specbinding, struct handler): More documentation.
	* eval.c (struct catchtag): More documentation.

1992-09-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* ymakefile (LIBX): Don't use -loldX.

1992-09-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* minibuf.c (get_minibuffer): Enable undo in minibuffers.

1992-09-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* ymakefile (LIBXMENU): Check NO_X_MENU, not HAVE_X_MENU
	* emacs.c (main): Use X menu code if HAVE_X_WINDOWS and not NO_X_MENU.
	* keyboard.c (read_char_menu_prompt): Likewise.

	* config.h.in: Delete everything about config.h.

	* emacs.c: Eliminate HIGHPRI as compilation option.
	(emacs_priority): New C variable, also Lisp variable.
	(main): Set the priority iff emacs_priority is nonzero.

1992-09-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* eval.c (entering_debugger): Variable renamed
	when_entered_debugger, and is now a timestamp based on
	num_nonmacro_input_chars.
	(init_eval): Initialize when_entered_debugger, not
	entering_debugger.
	(call_debugger): Set when_entered_debugger to the current value of
	num_nonmacro_input_chars.
	(find_handler_clause): Don't call debugger unless
	num_nonmacro_input_chars is greater than when_entered_debugger;
	that way, we won't call the debugger unless the user has had a
	chance to take control.
	(Fbacktrace): Don't clear entering_debugger here.
	* keyboard.h (num_nonmacro_input_chars): Added extern declaration
	for this.

	* fns.c (Fy_or_n_p): After testing for a QUIT, clear Vquit_flag.
	Otherwise, if Fy_or_n_p is called while Vinhibit_quit is true and
	the user presses C-g, this function goes into an infinite loop.

	* dispnew.c (get_display_line): Don't abort if the frame is
	invisible; since unmap events are handled at the interrupt level,
	a screen may become invisible at any time.

1992-09-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c (Fverify_visited_file_modtime):
	Pass buffer itself to handler, if have handler.
	(Fwrite_region): GCPRO around Fexpand_file_name, Ffile_name_directory.
	(Fread_file_name_internal): GCPRO around file name manip.
	(Ffile_writable_p, Ffile_readable_p): Use abspath, not filename,
	(Ffile_executable_p, Ffile_exists_p): to run the handler.
	(Fset_file_modes, Ffile_directory_p, Ffile_modes): Likewise.
	(Ffile_newer_than_file_p): GCPRO around expand_and_dir_to_file.

1992-09-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* s/bsd4-3.h: Give the BSD4_3 and BSD symbols the same numeric
	definitions they'll get in <sys/param.h>, to avoid warnings.

	* m/hp9000s300.h: Don't include <sys/wait.h>.  This really
	shouldn't be necessary.
	(BIG_ENDIAN): Define this as "4321", to agree with
	<machines/endian.h>, and avoid warnings.

	* systime.h: Re-arrange inclusion of <sys/time.h> and <time.h> so
	that they don't both get included under BSD, and do both get
	included under AIX.

	* xdisp.c (display_mode_line): If the only other frames are
	minibuffer frames, don't name the frame after the in the selected
	window.  We can use Fnext_frame to do this test easily.

1992-09-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* process.c (Faccept_process_output): Initialize useconds.

	* keyboard.c (num_nonmacro_input_chars): New variable.
	(read_char): Use num_nonmacro_input_chars to decide on auto-save & gc.
	Increment it when appropriate.
	(record_auto_save): Use num_nonmacro_input_chars.

	* fileio.c (Ffile_name_directory, Ffile_name_nondirectory):
	(Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
	Call find_file_handler.
	(syms_of_fileio): Set up Qfile_name_directory, etc.
	(Fcopy_file): Call find_file_handler for newname as well as for filename.
	(syms_of_fileio): Initialize Vfile_name_handler_alist.

1992-09-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callint.c (Fcall_interactively): Remove the 'K' interactive
	code, in favor of 'e'; that's a better name.

1992-09-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/esix5r4.h: New file.

        * sysdep.c (init_sys_modes): Handle VDSUSP like V_DSUSP.
        Use CDISABLE, not CDEL.
        Turn off IEXTEN if it exists.
        * systty.h (CDISABLE): New macro; may be defined from CDEL.

	* keyboard.c (command_loop_1): Bind inhibit-quit to t when in Fsit_for.

1992-09-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* Makefile.in: Add comments starting with "# DIST: " explaining
	that this gets munged by the configure script.

1992-09-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s-aix3-1.h (HAVE_GETHOSTNAME): Defined.

1992-09-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* frame.c (choose_minibuf_frame): abort if the selected frame has
	nil in its minibuffer_window slot; this shouldn't happen any more.
	* window.c (minibuffer_window): Accept an optional FRAME argument;
	if specified, return the minibuffer used by that frame.

	* keymap.c (describe_buffer_bindings): Adjust key_heading to match
	the format used by describe_map_tree.  Also, don't reprint the
	"key    binding" header above the global bindings if we've already
	printed it for the local bindings; it's clear enough that the
	columns mean the same thing as above.

1992-09-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ralloc.c (r_re_alloc): Instead of allocating a new bloc at the
	end of the heap, copying the data to it, and then freeing the
	original bloc, just expand the original block.  This saves a copy
	and a call to sbrk, and also removes the large spike in memory
	allocation that would occur when resizing large buffers.  And it's
	less code.

	* keyboard.h (Vkeyboard_translate_table): Declare this extern
	here, so describe_buffer_bindings can use it.
	* keymap.c (describe_buffer_bindings): Declare buf and bufend...

1992-09-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* systime.h: Always #include <time.h>, not just when NEED_TIME_H
	is defined.  It gets us struct tm.  #include <sys/time.h> whenever
	HAVE_TIMEVAL is defined and NEED_TIME_H isn't.

	* systime.h: Note that the tz_dsttime field of the struct timezone
	returned by gettimeofday doesn't say whether daylight savings is
	_currently- active; rather it specifies whether it is *ever*
	active.
	(EMACS_GET_TZ_OFFSET_AND_SAVINGS): Removed `savings_flag'
	argument, and renamed to EMACS_GET_TZ_OFFSET.  Don't try to
	extract savings information.  EMACS_CURRENT_TIME_ZONE should call
	localtime to figure out whether DST is active.

	* m/hp9000s300.h: #include <sys/wait.h> before doing anything
	else, to avoid conflicts between the system's and Emacs's
	definitions of BIG_ENDIAN.

	* keymap.c (describe_buffer_bindings): Set the current buffer to
	descbuf before calling current_minor_maps; that function's value
	depends on the values of buffer-local variables.  Don't set the
	current buffer to Vstandard_output until afterwards.

	* keymap.c (describe_buffer_bindings): If
	Vkeyboard_translate_table is in effect, describe its effects.

	* frame.c (Fnext_frame): Doc fix.

	* frame.c (prev_frame): #if 0'd out; nobody uses this.

	* frame.c (next_frame): The logic which determines whether a frame
	is acceptable to return was misarranged; rewrote it.
	(prev_frame): Same thing.

1992-09-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* syntax.c (scan_lists): Improve smarts for backwards scan of comments.
	Don't modify comstyle inside that loop.
	If string quotes don't match up, don't take value from OFROM;
	instead, parse forward using scan_sexps_forward.
	(scan_sexps_forward): Return value via a pointer passed in.
	New element in state contains char addr of last comment-starter seen.
	(Fparse_partial_sexp): Change call to scan_sexps_forward.

1992-09-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xmenu.c (xmenu_show): If no panes, just return.

	* keyboard.c (last_nonmenu_event): New var.
	(syms_of_keyboard): New Lisp var.
	(read_key_sequence): Use that instead of prev_event.
	* commands.h (last_nonmenu_event): Declared.
	* callint.c (Fcall_interactively): For `K', use last_nonmenu_event.
	Make `e' alias for `K'.

1992-09-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * editfns.c (Fcurrent_time_string): Change docstring to
        indicate that we will probably add the timezone to the end,
        now that we have it available on many systems.

	* xrdb.c: Don't include <X11/Xos.h>.  Under R4, it stupidly
	insists on defining SIGCHLD, even if it already has a definition.
	(file_p): Use the constant 4 instead of R_OK; empirically, the
	number is more portable than the symbol if you count the #include
	hair you have to go through to get R_OK defined.  Ffile_readable_p
	does this too.

	* xterm.c (x_wm_set_size_hint): Set the base_width and base_height
	members of size_hints, if they're available (X11R4 and after);
	otherwise, approximate the right thing, by using min_width and
	min_height as the base size.

1992-09-02  Barry A. Warsaw   (warsaw@anthem.nlm.nih.gov)

	Extended syntax.c in the following ways to support up to 2
	orthogonal comment styles per mode.  This is needed for C++.
	Bit 6 of syntax table entry for a character indicates
	it is part of the `b' comment style.  Otherwise it is
	part of the `a' style.
	* syntax.h (SYNTAX_COMMENT_STYLE): New macro.
	* syntax.c (Fmodify_syntax_entry): Set that flag for `b'.
	(describe_syntax): Print the `b' flag.
	(scan_lists, scan_sexps_forward): Handle the new flag.
	(Fparse_partial_sexp): Return new element in value.

1992-09-02  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

	* fileio.c (syms_of_fileio): Doc fix for Vfile_name_handler_alist.

1992-09-02  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (kbd_buffer_get_event): When performing the
	FRAME_FOCUS_FRAME redirection, don't modify the frame field of
	the event; that fatally corrupts mouse click events.  Instead,
	just perform the redirection on the value assigned to
	Vlast_event_frame.

	* callint.c (Fcall_interactively): Don't try to get the
	`enable-recursive-minibuffers' property from FUNCTION unless
	FUNCTION is actually a symbol; there are some cases where a key
	sequence is bound directly to a lambda form, and there's no reason
	to break these.

	* window.c (Fset_window_configuration): Don't signal an error
	if the frame size saved in the window configuration doesn't
	match the frame's current size; instead, temporarily resize
	the frame while installing the window configuration.  This is
	important because using the minibuffer saves and restores the
	current window configuration, and you don't want to signal an
	error just because the user resized the frame while using the
	minibuffer.

	* doc.c (Fsnarf_documentation): Signal an error if this is
	called in a dumped Emacs.

	* alloc.c (mark_object): mark a symbol's name after marking its
	value, function, and property list rather than before; this way,
	symbols' names are readable, giving us a chance to detect some
	kinds of heap corruption.

1992-09-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* emacs.c (__main, __do_global_dtors): New dummy functions.
	(__do_global_ctors_aux, __do_global_ctors): Fix typo in fn names.

1992-09-01  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* prefix-args.c: New file.  See comment at top of file.
	* ymakefile (YMF_PASS_LDFLAGS): Use the prefix-args program to
	affix the -Xlinker prefix to the linker arguments.
	(prefix-args): New target.
	(temacs): Depend on prefix-args.

	* xterm.c (x_catch_errors): Don't forget to initialize
	x_caught_error_message to the null string, so x_check_errors can
	tell when an error has occurred.

	* unexmips.c (mark_x): Declare this as static void at the top of
	the file and at the function definition.

	* keyboard.c (input_available_signal): Declare this to return
	SIGTYPE.

	* xrdb.c (getuid): Declare this to return short.

	* s/bsd4-3.h: Remove definition of SIGTYPE macro; Mt. Xinu says
	it's int, but Ultrix says it's void.  Since the SIGTYPE guessing
	code in the `configure' script gives the correct answer for both
	of these cases, there's no point in listing it here.

	* systime.h (EMACS_CURRENT_TIMEZONE): Change documentation to
	indicate that *OFFSET should be set to the number of minutes EAST
	of Greenwich, which is what Ed Reingold says real time gurus want.
	Changed the definition of the EMACS_GET_TZ_OFFSET_AND_SAVINGS
	macro to reflect this.  Buggily, the Fcurrent_time_zone function
	was already expecting minutes east of GMT.

	* Makefile.in (distclean): Remove backups from the `m' and `s'
	directories, too.

	* m/mips.h: Merge changes from Emacs 18.58:
	[NEWSOS5]: Changes so this file can be used with s/newsos5.h.
	(SIGN_EXTEND_CHAR): Define this using a cast to signed char.  I
	guess the MIPS compiler and its derivatives all have this type.
	(HAVE_ALLOCA, C_ALLOCA): Define the former if we're compiling with
	GCC, and the latter otherwise.
	(C_SWITCH_MACHINE): Defined, instead of C_SWITCH_SYSTEM.
	(LINKER): Defined, if BSD.
	(XUINT, XSET, XUNMARK): Add parentheses to eliminate warnings from
	GCC.  Reindent to fit in 80 columns.
	INHIBIT_BSD_TIME prevents including bsd/sys/time.h.
	* s/newsos5.h: New file for Sony NEWS-OS release 5, courtesy of
	Chris Hanson <cph@klia.ai.mit.edu>.

	* m/mips.h: Don't undefine LOAD_AVE_TYPE; the comment says that
	Emacs 19 has the crocks to handle it properly.

	* m/pmax.h: Merge changes from Emacs 18.58:
	(LIB_STANDARD, COFF, TERMINFO): Cancel out definitions from
	m/mips.h which are only appropriate for USG.
	(MAIL_USE_FLOCK, HAVE_UNION_WAIT): Do define these.
	(BROKEN_O_NONBLOCK): Defined.
	(LINKER): Don't define this.
	[OSF1]: Undef C_ALLOCA, define HAVE_ALLOCA.

	* s/osf1.h: New file.

	* s/bsd4-3.h: Merge changes from Emacs 18.58:
	(BSD, BSD4_3): Just define these, don't fret about numerical
	values or version numbers.

	* m/hp9000s300.h: Merge changes from Emacs 18.58, and hp300bsd.h:
	Change configuration note to say it's okay to use this file for BSD.
	Add comment saying that NOMULTIPLEJOBS must be defined for
	versions of HP/UX before 6.5.
	Don't define BIG_ENDIAN if it seems that <endian.h> has already
	done so.
        [BSD4_3] Define m68000, instead of hp9000s300; crt0.c uses these
	to decide what sort of startup code to use.
	[not BSD4_3] Under HP/UX, always define the BSD memory functions
	(bcopy, bzero, and bcmp) in terms of the SYSV string functions
	(memcpy, memset, and memcmp), not just under HP/UX 5; version 6's
	BSD compatibility library has reported bugs in `signal'.
	(NEED_BSDTTY): Move this symbol's definition inside the "not
	BSD4_3" conditional, since it's only relevant to HP/UX.
	* m/hp300bsd.h: File deleted, since m/hp9000s300.h now
	works with both HP/UX and BSD; it includes m/hp300bsd.h's
	specifications.

	* m/hp9000s300.h: Remove definition for SIGN_EXTEND_CHAR; this is
	only used by the regexp code, which has its own portable
	definition these days.

1992-08-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keymap.c (Fmake_sparse_keymap): New optional arg.  Callers changed.
	(Fmake_keymap): Likewise.

	* emacs.c (__do_global_ctors, __do_global_ctors_aux): New dummy fns.
	(__CTOR_LIST__, __DTOR_LIST__): New dummy variables.

	* fileio.c (Fdo_auto_save): Always call record_auto_save.

	* keyboard.c (read_char): Call read_char_menu_prompt here.
	Accept 4 new args to pass to it.  Include them in recursive call.
	Don't delay before starting echo if prev_event was a mouse event.
	Test for eof in batch mode now understands C is a Lisp_Object.
	(read_key_sequence): Don't call it here; always call read_char.
	Don't change last_event_buffer after a mouse menu input.
	(read_char_menu_prompt): Arg PROMPT deleted.
	Return nil if nothing to do.

	* xmenu.c (Fx_popup_menu): Treat coords relative to spec'd window.
	(single_keymap_panes): New function; contains guts of keymap_panes.
	If a command binding for submenu has a prompt string starting with @,
	make a separate pane for it at this level.

	* xfns.c (Fx_track_pointer): Pass new args to read_char.
	(Fx_select_region, Fx_horizontal_line): Likewise.
	* lread.c (Fread_char): Pass new args to read_char.
	(Fread_event, Fread_char_exclusive): Likewise.
	* fns.c (Fy_or_n_p): Pass new args to read_char.

1992-08-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (read_key_sequence): Keep track of prev_event.
	Pass new proper args to read_char_menu_prompt.
	(read_char_menu_prompt): New arg prev_event.  Use Fx_popup_menu.
	Handle any number of keymaps, not just LOCAL and GLOBAL.
	Invert meaning of arg PROMPT.  Test of menu_prompting was backwards.

	* keymap.c (keymap_table): No longer static.

	* xmenu.c (keymap_panes): New function.
	(Fx_popup_menu): Accept keymap or list of keymaps as MENU argument.
	Accept mouse button event as POSITION argument.

1992-08-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* cmds.c (internal_self_insert): Assume Fexpand_abbrev expanded
	something if it incremented MODIFF.

1992-08-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* unexmips.c (unexec): Allow sections in any order.
	Adjust addresses of rdata section as well as data section.

	* buffer.c (syms_of_buffer): Made buffer-display-table,
	buffer-field-list and buffer-undo-list allow any type of value.

1992-08-27  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fns.c (Fappend): Doc fix.

1992-08-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* s/usg5-4.h: Incorporate changes from 18.58:
	(LIBX10_SYSTEM): Undefine this.
	(GNULIB): Definition deleted -- done in ymakefile.
	(LIB_STANDARD): Don't use GNULIB.
	(HAVE_TCATTR): Defined.

	* xfns.c (x_icon): Don't call x_wm_set_icon_positions if the user
	hasn't specified the icon position.  Let the window manager put
	the icon where it likes.

        * xterm.c (x_make_frame_invisible): Don't forget to check the
	return value of XWithdrawWindow; it could indicate that the window
	wasn't successfully redrawn.

	* sysdep.c (init_baud_rate): Re-arranged order of conditionals -
	test TERMIOS before TERMIO; when two options might both be
	defined, test the most recent first, so that the most recent
	functions get used.

	* sysdep.c [HAVE_TERMIO] (init_baud_rate): Don't use tcgetattr
	unless HAVE_TCATTR is defined.  Only very rarely do termio systems
	have the tc{get,set}attr macros.

	* window.c (coordinates_in_window): Do not assume that all
	one-line windows are the minibuffer, or that all minibuffers are
	one line high.  Use MINI_WINDOW_P.

        * systerm.h: Renamed to systty.h, to be more consistent with
	everything else in Unix.
	* dispnew.c, emacs.c, keyboard.c, process.c, sysdep.c: #include
	directive changed.
	* ymakefile: References to systerm.h changed.

	* s/usg5-3.h: Merged changes from 18.58:
	(HAVE_SYSV_SIGPAUSE): Defined.
	(BROKEN_TIOCGETC): Defined.

1992-08-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* process.c (WCOREDUMP): Define only if not defined.
	(create_process) [HAVE_SETSID]: Use TIOCSCTTY if exists.

1992-08-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fileio.c (Fdo_auto_save): Call Fsleep_for with the appropriate
	number of arguments.
	* fns.c (Fyes_or_no_p): Same.

	* dispnew.c (update_frame): Change the way we handle
	cursor_in_echo_area.  Firstly, ignore this if the frame we're
	updating doesn't have a minibuffer.  Secondly, don't handle the
	selected frame specially.  Thirdly, don't assume that the
	minibuffer is only one line high.  If cursor_in_echo_area < 0, put
	the cursor in the upper-left corner; if cursor_in_echo_area > 0,
	put it on the lowest non-empty line in the minibuffer window, or
	on the top line.

	* dispnew.c (direct_output_for_insert): Fail if
	cursor_in_echo_area is set; we don't want to do the typing there.
	(direct_output_for_insert): Same.

1992-08-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
	available [HAVE_X11R4]; send the UnmapNotify event when
	appropriate [HAVE_X11]; just unmap the window if that's all that's
	needed [not HAVE_X11].

	* xterm.c (x_set_text_property): Removed; it's only called from
	one place.  Who wants *another* layer of indirection?
	* xfns.c (x_set_name): Use XSetWM{Name,IconName} when available
	[HAVE_X11R4], or XSetIconName and XStoreName otherwise.

	* xterm.h (FRAME_X_WINDOW): New macro, for readability.
	* xterm.c, xfns.c, xselect.c: Use it.

	* emacs.c (Fkill_emacs): Doc fix.
	(syms_of_emacs): Doc fix for Vkill_emacs_hook.

	* xterm.c (x_death_handler): Renamed to x_connection_closed.
	(x_term_init): Use x_connection_closed as the SIGPIPE handler.

	* xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
	x_error_handler): Removed; you can't catch X errors this way,
	since you can't perform X operations from within an X error
	handler, and even though we call error, we're still within an X
	error handler.
	(x_error_quitter, x_error_catcher): New functions, for panicking
	on and catching X protocol errors.
	(x_caught_error_message): Buffer for caught X errors.
	(x_catch_errors, x_check_errors, x_uncatch_errors): New functions
	for catching errors.
	(x_term_init): Set the error handler to x_error_quitter, rather
	than x_error_handler.
	* xfns.c (x_set_mouse_color): Use x_catch_errors, x_check_errors,
	and x_uncatch errors to avoid crashing if the user selects an
	odd cursor.

	* xterm.c (x_proto_requests): Removed; it's not important.

	* xterm.c (events): Array removed; it's not used.

	* xfns.c (select_visual): Use XVisualIDFromVisual when available
	[HAVE_X11R4].

	* xrdb.c (get_user_db): Use XResourceManagerString when available
	[HAVE_X11R4].

	* window.c (change_window_height): If the size of the window will
	shrink below the minimum, this code would only try to delete it if
	it had a parent.  Well, even if the window doesn't have a parent,
	you want Fdelete_window to signal an error, since you're trying to
	resize one of the undeleteable windows into nothingness.  So call
	Fdelete_window even if the window doesn't have a parent.

	* window.c (MINSIZE): Add kludge so that the minibuffer is always
	allowed to shrink to one line in height.
	(MINSIZE, CURBEG, CURSIZE): Change these so that their argument
	are always Lisp_Objects, not struct window *'s.
	(change_window_height): Changed accordingly.

1992-08-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * frame.h (struct frame): New member - explicit_name.
	* frame.c (make_frame): Clear it.
	* xfns.c (x_set_name): Take new argument EXPLICIT, instead of
	OLDVAL.
	(x_explicitly_set_name, x_implicitly_set_name): New functions.
	(x_frame_parms): Use x_explicitly_set_name here.
	(x_window): Use x_implicitly_set_name here.
	* xdisp.c (display_mode_line): Use x_implicitly_set_name here.

	* xterm.c (x_wm_hints): Variable deleted.  This has to be
	per-screen.  Duh.
	* xterm.h (struct x_display): New member: wm_hints.
	* xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap,
	x_wm_set_icon_position): Use F->wm_hints, rather than x_wm_hints.
	(x_term_init): Don't initialize x_wm_hints here.
	* xfns.c (Fx_create_frame): Instead, initialize f->x_wm_hints
	here.

	* xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs
	and UNBLOCK_INPUTs.  And remember that VALUE is the string we want
	to set the name to, not PROPERTY.

1992-08-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* frame.c (make_minibuffer_frame): Don't set this to auto-raise by
	default.  It's annoying.

	* frame.c (make_minibuffer_frame): Set the prev field of the
	minibuffer window on a minibuffer-only frame to Qnil, rather than
	having it point to itself.  This confuses code (Fprevious_window
	and change_window_height, for example), and is only an attempt to
	support a convention that can't really be used in Emacs 19 anymore.
	* window.h: Document the fact that we can no longer assume that
	the minibuffer's previous window is the root window, since a
	minibuffer window in a minibuffer-only frame has a prev field of
	nil.
	* frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this by
	reference to the_only_frame.root_window, rather than by assuming
	that minibuf_window->prev is the root window.  While this is true
	in the non-multi-frame case, we want to discourage this assumption
	in code.
	* dispnew.c [not MULTI_FRAME] (Fredraw_display): Use
	FRAME_ROOT_WINDOW instead of minibuf_window->prev.
	* xdisp.c (redisplay, init_xdisp): Same.
	* window.c (Fset_window_configuration): Removed #if 0'd code which
	assumes that minibuf_window is on the same frame as the window
	configuration.  Removed special case for windows whose prevs
	point to themselves.

	* window.c (Fset_window_configuration): Rename the argument from
	ARG to CONFIGURATION, so it matches the docstring.  The
	make-docfile program cares.

	* window.c [MULTI_FRAME] (syms_of_window): Don't staticpro
	minibuf_window; the frame list will take care of it.

	* xterm.h (HAVE_X11R4): Since we can autodetect this, and can
	write code more likely to be future-compatible, define this when
	appropriate.
	* xterm.c (x_set_text_property): Define this appropriately for
	X11R3 and X11R4.

	* xterm.c (x_set_text_property): Make this take a Lisp_Object
	string as an argument, rather than a pointer and a length.
	* xfns.c (x_set_name): Caller changed.

	* xfns.c (x_get_arg): Accept a new type - symbol.  If we've
	retrieved a string from the xrdb database and the user wants a
	symbol, intern it.
	(Fx_create_frame): Use the symbol type here.

	* xfns.c (x_figure_window_size, x_icon, Fx_create_frame): Use
	values from enum resource_types for the last arg to x_get_arg,
	instead of passing numbers.

	* xfns.c (Fx_create_frame): When setting up the scroll bars, use
	the type parameter to x_default_parameter, rather than prefixing
	the resource name with a question mark.

	* xfns.c [not HAVE_X11] (Fx_create_frame): The resource which
	determines whether or not to use a bitmapped icon is called
	"IconType", not "BitmapIcon".  Update this.

1992-08-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c: Doc fixes.

        More SYSV portability changes from Eric Raymond:

	* xterm.c [USG5]: Don't include <sys/types.h>.

	* xterm.c (x_make_frame_invisible): Instead of calling XWithdraw
	window, which isn't widely available, write out what it does,
	since that's not much.
	(x_iconify_frame): Explicitly perform both the X11R3 and X11R4
	methods for iconification; don't use XIconifyWindow, since that's
	not present in R3.

	* xterm.c (x_wm_set_size_hint): Don't bother setting the
	base_width and base_height members; their function is performed
	just as well by the min_width and min_height members, and if we
	use XSetNormalHints instead of XSetWMNormalHints, we can be
	compatible with R3.

	* xterm.c (x_error_handler): There is no way to invoke the default
	error handler which works on all versions of X11, so don't bother;
	call XGetErrorText and print the message ourselves.

	* xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't
	defined on all systems.  Since we only use that as an initial
	guess anyway, it's not very important.

1992-08-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* abbrev.c (Fexpand_abbrev): If pre-expand hook changes the buffer,
	assume that means we "did an expansion".

	* cmds.c (internal_self_insert): Ignore value of Fexpand_abbrev;
	instead, check whether buf is modified when it returns.

1992-08-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        Applied SYSV portability changes from Eric Raymond:

	* xrdb.c [USG5]: Define SYSV, and then include <unistd.h>.
	Apparently, Xlib.h include string.h if SYSV is defined, and
	strings.h if not.
	Don't include <sys/types.h>; just declare getuid to return an
    	int.  Big deal.
	(MAXPATHLEN): If this is not defined by the system's include
    	files, give it a value of 256.
	(get_user_db): Fetch the defaults directly from the display
    	structure, rather than using XResourceManagerString; that
    	function doesn't exist in the older versions of X.

	* xterm.c (x_set_text_property): New function.
	* xfns.c (x_set_name): Use it instead of XSetWMName and
    	XSetWMIconName.

	* xfns.c (select_visual): Fetch the visual id directly from v;
    	don't call XVisualIDFromVisual, since that function is not
    	available in earlier versions of X.

	* term.c (term_get_fkeys): Some systems define `static' to be the
    	empty string, which means that you can't have constant
    	initialized arrays inside a function.  So move the `keys' array
    	outside of the function.
	* xdisp.c (decode_mode_spec): Same deal, with lots_of_dashes.
	* xfns.c (x_make_gc): Same deal, regarding cursor_bits.

	* term.c (keys): Include definitions for "K2" (the center key on
    	an IBM keypad), "F1" (F11), and "F2" (F12).  Handle "k0" and "k;"
    	specially; see the code for details.

	* term.c (clear_end_of_line): Remember that on some systems,
    	"static" gets defined to be the null string, so we can't declare
    	an array to be static and then initialize it.  Since the array in
    	question (buf) is only one element long, just make it a scalar
    	rather than an array; it can then be initialized, even if it's
    	not static.

	* systime.h [not HAVE_TIMEVAL] (EMACS_USECS, EMACS_SET_USECS):
    	Don't forget to define dummy versions of these.

	* systime.h [USE_UTIME]: time_t is a typedef, not a struct.
    	Don't prefix it with `struct'.

	* systerm.h (EMACS_SET_TTY_PGRP): When there doesn't seem to be
    	any way to do this, don't forget to give it a dummy definition.

	* sysdep.c (select): There's no need to cast the return value of
    	signal anymore, since we have the SIGTYPE macro defined.

	* sysdep.c (read_input_waiting): When scanning for quit
    	characters, use the value of quit_char, rather than assuming that
    	C-g is the quit character.  And don't forget to declare i.

	* sysdep.c [USG5]: Don't include fcntl.h.

	* s/usg5-3.h: Eric Raymond writes:
	Define HAVE_SELECT and BSTRINGS only if HAVE_X_WINDOWS is on,
	because that means we'll be linking in the shared libraries
	containing the BSD emulations.  Teach the file about the shared
	libraries necessary to link X programs, because AT&T doesn't
	supply static libraries for X.  Also, fix the incorrect assertion
	that -lg cannot be used with SVr3.  Finally, force USE_UTIMES and
	BROKEN_TIOCGWINSZ.  (Note for the future; there may be a
	utimes(2)) emulation lurking in the X shared libraries.)

	* s/usg5-4.h (USE_UTIME): Remove this definition; the C library
    	still doesn't have utimes.

	* ralloc.c (get_bloc): When initializing new_bloc->variable, cast
	NIL to (POINTER *).
	(malloc_init): Give warning if sbrk returns zero.  Wonder what
	that's supposed to mean.

	* process.c (process_send_signal): Don't send SIGTSTP if the
	system doesn't have that facility.

	* process.c: [USG5] Don't include <fcntl.h>.
	[USG] Don't bother including <termios.h>, <termio.h>, or
	<fcntl.h>; systerm.h takes care of all that.
	Remove the "mis;tak-+;;" line from the code; apparently this
	section of code does get used.

	* minibuf.c (Fread_from_minibuffer): Put this function's doc
	string into a comment; it's too long for the PCC preprocessor.
	Rah.
	(Fcompleting_read): Same deal.

	* keyboard.c (init_keyboard): Changed "#endif SIGIO" to
	"#endif /* SIGIO */"
	* mocklisp.c (Fml_substr): Same sort of thing.
	* process.c (wait_reading_process_input): Same.

	* floatfns.c (Fexpm1, Flog1p): Function removed; it's not widely
	available, and hardly vital.
	(syms_of_floatfns): Adjusted appropriately.

	* floatfns.c (Flog): Accept optional second arg, being the base
	for the logarithm.
	[USG] (Flogb): Define this in terms of Flog.

	* data.c [USG] (Frem): Call fmod, rather than drem.  Rah.

	* emacs.c [USG5]: Don't #include <fcntl.h> for these systems.

	* alloc.c (Fmake_marker): Removed the test for being called from a
	signal handler.  The original bug is probably gone, the test
	wasn't written portably, and it should probably go somewhere else
	anyway - say, funcall or eval.

        End of changes from Eric Raymond.

	* xfns.c (Fx_create_frame): Make the default for the icon-type
    	parameter nil, not t.  It seems to cause problems with some X
    	servers.

	* lisp.h (DEFVAR_PER_BUFFER): Add new argument, TYPE, to help
	check the types of buffer-local variable slots.
	* buffer.c (syms_of_buffer): Call DEFVAR_PER_BUFFER with the new
	TYPE argument.
	* abbrev.c (syms_of_abbrev): Same.
	* buffer.c (buffer_local_types): New variable.
	(buffer_slot_type_mismatch): New function.
	* buffer.h (buffer_local_types): New extern declaration.
	* data.c (store_symval_forwarding): When storing through a
	Lisp_Buffer_Objfwd, check if the slot requires a particular type,
	and report an error if the types clash.
	* lread.c (defvar_per_buffer): Support new TYPE argument, by
	setting the appropriate slot in buffer_local_types.

1992-08-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* window.c (window_loop): This used to keep track of the first
	window processed and wait until we came back around to it.  Sadly,
	this doesn't work if that window gets deleted.  So instead, use
	Fprevious_window to find the last window to process, and loop
	until we've done that one.

	* window.c [not MULTI_FRAME] (init_window_once): Don't forget to
	set the `mini_p' flag on the new minibuffer window to t.

	* window.c (Fwindow_at): Don't check the type of the frame
	argument.

	* window.c [not MULTI_FRAME] (window_loop): Set frame to zero,
	instead of trying to decode it.

	* frame.h [not MULTI_FRAME] (the_only_frame): Put a comment above
	this indicating that it's not GCPRO'd.  Put parens around some of
	the FRAME_* macros' definitions.
	[not MULTI_SCREEN] (Fselected_frame): New function.

	* frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this in
	terms of minibuf_window, rather than by reference to
	the_only_frame.
	* window.c (init_window_once): Initialize minibuf_window before
	FRAME_ROOT_WINDOW, so the latter actually points to something.

	* keyboard.c (Fexecute_mouse_event): dyked-out function deleted.
	We're not going to use this mouse interface.
	(Vmouse_window, Vmouse_event, Vmouse_event_function,
	Vmouse_left_hook, Vmap_frame_hook, Vunmap_frame_hook,
	Vmouse_motion_handler): Variables deleted; they were to be used by
	Fexecute_mouse_event.
	(syms_of_keyboard): Same.
	(command_loop_1): Remove dyked-out code to support
	Fexecute_mouse_event.
	(read_char): Same.

	* keyboard.c (Vlast_event_frame): Don't define this window if
	MULTI_FRAME is not #defined.
	(syms_of_keyboard): Same.
	(kbd_buffer_store_event): Don't try to work with Vlast_event_frame
	if MULTI_FRAME is not #defined.
	(kbd_buffer_get_event): Same.

	* keyboard.c (Fdiscard_input): Removed dyked-out code from when
	unread_command_char's quiescent value was -1, not nil.

	* frame.c (make_frame): Stop passing zero to make_window; it's not
	expecting any arguments.

1992-08-12  Jim Blandy  (jimb@albert.gnu.ai.mit.edu)

	* unexsunos4.c: Deleted "$Log" header in comments at top of file;
	this was beginning to grow RCS hair, which we don't want.
	* xmenu.c: Same deal.

1992-08-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fileio.c (Fread_filename): Don't add one here.
	* minibuf.c (Fcompleting_read): Instead, stop subtracting one
	here, so this function lives up to its doc string, which I think
	specifies an okay way to work.

	* doc.c (Vdata_directory): Removed; this is declared in callproc.c.
	(syms_of_doc): Initialization removed.

	* xfns.c (x_get_arg): Return Qunbound for an unspecified
	resource, not nil.  That way, we can tell the difference between a
	false resource and an unspecified resource.
	(x_default_error): Use DEFLT if x_get_arg returns Qunbound, not Qnil.
	(x_figure_window_size, x_icon, Fx_create_frame): Deal with
	Qunbound and Qnil properly.

	* xfns.c (Fx_create_frame): Pass the correct number of arguments
	to x_set_font.

	* xfns.c [not HAVE_X11] (Fx_create_frame): Delete section that's
	only included if we *do* have X11.  Blind patching.

        * xfns.c (x_icon): Rewritten to call x_wm_set_icon_position and
	x_wm_set_window_state instead of calling XSetWMHints directly.
	* xterm.c (x_wm_hints): New variable.
	(x_wm_set_window_state, x_wm_set_icon_pixmap,
	x_wm_set_icon_position): Use x_wm_hints.
	(x_term_init): Set the `input' field of x_wm_hints, and its flag.

	* xterm.c (x_text_icon): Call x_wm_set_icon_pixmap with a pixmap
	of zero, to clear the pixmap.
	(x_wm_set_icon_pixmap): Accept this protocol; if pixmap is zero,
	specify no pixmap for the icon.

	* xfns.c (x_default_parameter): Don't call store_frame_param here;
	it's already taken care of by x_set_frame_parameters.

	* xfns.c (Fx_create_frame): Check for the `icon-type',
	`auto-raise', and `auto-lower' parameters. Have `icon-type'
	default to t, indicating that we want the nifty gnu in our icons.
	(Qauto_lower): New symbol.

	* xfns.c (x_set_icon_type): UNBLOCK_INPUT before reporting the
	error, not after.  error doesn't return, sklitch-brain.

	* xterm.c (x_set_window_size): Call check_frame_size to make sure
	that the requested dimensions are within acceptable limits.
	Store the new size information in the frame structure.

	* xfns.c (x_set_frame_parameters): Properly recognize changes to
	the height of the frame.  Recognize changes of the frame's
	position.

	* xfns.c (x_set_frame_parameters): Iterate over ALIST while the
	current element is cons, not while it's non-nil.
	(syms_of_xfns): Call init_x_parm_symbols after interning all the
	other atoms; init_x_parm_symbols expects Qx_frame_parameter to be
	initialized.

1992-08-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xfns.c (Qbackground_color, Qborder_color,  Qborder_width,
	Qcursor_color,  Qfont,  Qforeground_color,  Qgeometry,
	Qhorizontal_scroll_bar,  Qicon_left,  Qicon_top,  Qiconic_startup,
	Qinternal_border_width,  Qleft,  Qmouse_color,  Qparent_id,
	Qsuppress_icon,  Qsuppress_initial_map,  Qtop,  Qundefined_color,
	Qvertical_scroll_bar,  Qwindow_id,  Qx_frame_parameter): New
	symbols, with lisp code to rebuild syms_of_xfns.
	(syms_of_xfns): Initialize and staticpro them.
	(Qheight, Qminibuffer, Qname, Qnone, Qonly, Qwidth,
	Qunsplittable): Add extern declaration for these.
	(x_init_parm_symbols): Don't initialize Qx_frame_parameter here;
	it's done in syms_of_xfns.
	(x_default_parameter): Change the argument char *PROPNAME into a
	Lisp_Object PROP; let the caller take care of interning the atom.
	(Fx_geometry, x_figure_window_size, x_icon, Fx_create_frame): Use
	the new Q... variables, instead of interning things.

	* frame.c (Qheight, Qicon, Qmodeline, Qname, Qnone, Qonly,
	Qunsplittable, Qwidth, Qx): New symbol, with lisp code to rebuild
	syms_of_frame.
	(syms_of_xfns): Initialize and staticpro them.
	(Fframep, Fframe_visible_p, Fframe_parameters):  Use
	the new Q... variables, instead of interning things.
	(store_in_alist): Change the argument char *PROPNAME into a
	Lisp_Object PROP; let the caller take care of interning the atom.

	* frame.c (Fframe_visible_p): Doc fix.

	* frame.c (Fframe_parameters): When figuring the `minibuffer'
	parameter, if FRAME doesn't have a minibuffer, return `none', not
	nil.  If it does have a minibuffer with other windows, return the
	window.

	* frame.c (Fmodify_frame_parameters): Don't write out the loop for
	processing X frame parameters here; do it in the x specific code.
	Call the function which deals with this stuff
	x_set_frame_parameters, not x_set_frame_parameter.
	* xfns.c (x_set_frame_param): Replaced by x_set_frame_parameters.
	(x_set_frame_parameters): Process the alist of parameters here.
        Notice `width', `height', `top', and `left' parameters.
        Hold off changing the frame size and position until the end, so we
	can do both parameters at once when they are both specified.
	(x_default_parameter): Call x_set_frame_parameters, not
	x_set_frame_param.

	* frame.c (Fmake_frame_visible, Fmake_frame_invisible,
	Ficonify_frame, Fframe_parameters, Fmodify_frame_parameters,
	Fset_frame_height, Fset_frame_width, Fset_frame_size,
	Fset_frame_position): Place clauses controlled by FRAME_X_P inside
	`#ifdef HAVE_X_WINDOWS ... #endif' clauses.

	* frame.c (Fset_frame_position): Doc fix.

	* dispnew.c (Fredraw_frame): Call clear_frame_records before
	calling update_end, so that x_display_box_cursor can rely on the
	contents of f->current_glyphs.

	* xfns.c (x_figure_window_size): Indicate that this function
	returns an int, rather than just leaving it unstated.

	* xterm.c (x_wm_set_size_hint): Don't try to set the base_height
	and base_width elements of size_hints if PBaseSize is not
	#defined.  Set the minimum frame size according to the information
	returned by check_frame_size.

	* window.h (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
	removed.
	(check_frame_size): New extern declaration.
	* window.c (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
	defined here now.
	(check_frame_size): New function.
	* dispnew.c (change_frame_size): Call check_frame_size here,
	rather than writing out its code.  Don't declare newheight and
	newwidth to be register variables, since we take their address.

	* bytecode.c (Fbyte_code): When metering the Bcall opcodes, make
	sure the count on the symbol's `byte-code-meter' property does not
	overflow.

	* bytecode.c (syms_of_bytecode): Add a docstring for
	byte-metering-on.

1992-08-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c (in_display): Variable deleted; it's only ever used as
	an unofficial parameter to change_frame_size.
	(change_frame_size): New argument, DELAY, which when non-zero
	indicates to delay the size change until later.  This should be
	passed as one from signal handlers.
	(window_change_signal): Call change_frame_size with a DELAY of 1.
	(do_pending_window_change): Call change_frame_size with DELAY of 0.
	* frame.c [MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
	Fset_frame_size): Same.
	[not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
	Fset_frame_size, Fset_screen_height, Fset_screen_width): Same.
	* keyboard.c (Fsuspend_emacs): Call change_frame_size with the
	proper arguments - the height and width are the second and third
	arguments, not the first and second.  Pass 0 for DELAY.
	* xfns.c (Fx_create_frame): Call change_frame_size with a DELAY of 0.
	* xterm.c (XTread_socket, x_do_pending_expose): Call
	change_frame_size with a DELAY of 1.

	* xterm.c (in_display): Deleted this; it's never used in xterm.c,
	and there is another variable by the same name in dispnew.c.

	* frame.c [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
	Fset_frame_size, Fframe_height, Fframe_width): New functions, for
	use when Emacs is not compiled with multiple screens.
	[not MULTI_SCREEN] (Fset_screen_height, Fset_screen_width):
	Functions added for backward compatibility with Emacs 18.  These
	would be just aliases, except that the version 18 functions don't
	take a FRAME argument.
	[not MULTI_SCREEN] (syms_of_frame): New function, to defsubr the
	above and add screen-height and screen-width as aliases for
	Fframe_height and Fframe_width.
	* emacs.c (main): Call syms_of_frame unconditionally.  When
	MULTI_FRAME is not defined, it still provides the Fframe_width,
	Fframe_height, Fset_frame_width, and Fset_frame_height functions.

	* frame.c (Fset_frame_width): Change the size of FRAME, not of
	selected_frame.

	* frame.c (Fset_frame_width, Fset_frame_height): Declare the
	`frame' argument to be a Lisp_Object.  It used to be undeclared.

1992-08-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c, frame.c, frame.h, keyboard.c, scroll.c, term.c,
	window.c, xdisp.c, xfns.c xterm.c (FRAME_IS_TERMCAP, FRAME_IS_X,
	FRAME_HAS_MINIBUF): Renamed these to FRAME_TERMCAP_P, FRAME_X_P,
	and FRAME_HAS_MINIBUF_P, for consistency with the rest of the
	frame macros.

	* window.h (MIN_SAFE_WINDOW_WIDTH, MIN_SAFE_WINDOW_HEIGHT): New
	macros.
	* window.c (check_min_window_sizes): New function.
	(set_window_height): Call it.
	(Fsplit_window, change_window_height): Call it, instead of writing
	out its code.
	* dispnew.c (change_frame_size): If newlength or newwidth are too
	small (according to the value of MIN_SAFE_WINDOW_{WIDTH,HEIGHT}),
	force them larger.  This isn't really right, but it's better than
	crashing.

	* editfns.c (Fcurrent_time_zone): Doc fix.

1992-08-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* editfns.c (Fcurrent_time_zone): Don't forget to include code to
	signal an error when EMACS_CURRENT_TIME_ZONE is not defined.

1992-08-06  Joseph Arceneaux  (jla@gnu.ai.mit.edu)

        * doc.c (Vdata_directory): Declared.
	(syms_of_doc): Initialized.

	* fileio.c (Fread_filename): Add 1 to the offset position for the
	cursor when reading file names.

1992-08-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* systime.h (EMACS_CURRENT_TIME_ZONE): New macro.
	* editfns.c (Fcurrent_time_zone): New function.
	(syms_of_editfns): defsubr it.

	* keyboard.c (read_key_sequence): Clear the eighth bit of the
	character from the key sequence, NOT the index of the character IN
	the key sequence.  How many tries will it take to get it right?

1992-08-04  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* eval.c (syms_of_eval): Doc fix for debug-on-quit.

1992-08-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callproc.c (Fcall_process): Doc fix.  Used to claim that
	Fcall_process doesn't wait when BUFFER was nil.  It does.

1992-07-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (read_key_sequence): Scan for function keys when t >=
	mock_input, not when t > mock_input.  We do want to scan for
	function keys when t == mock_input.

	* keyboard.c (read_key_sequence): Don't increment fkey_end when
	testing to see if keybuf[fkey_end] is a meta-character.

1992-07-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* Makefile.in (TAGS): Generate tags for files in ../external-lisp
	too.

1992-07-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* eval.c (find_handler_clause): For quit, don't check Vdebug_on_error.
	(wants_debugger): Rewrite so it cannot get an error.

	* callint.c (Fcall_interactively): Handle enable-recursive-minibuffers
	property on the command, by enabling recursive minibuffers.
	(syms_of_callint): Set Qenable_recursive_minibuffers.

1992-07-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* frame.c (Fmake_frame_visible, Fmake_frame_invisible,
	Ficonify_frame): Make the first argument optional, defaulting to
	selected_frame.
	(Ficonify_frame, Fmake_frame_invisible): Add interactive specs, so
	we can bind these directly to C-z.

1992-07-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c (Fread_file_name): Use new calling convention for
	Fcompleting_read, with history as Qfile_name_history.
	(syms_of_fileio): Set Qfile_name_history; set the var to nil.
	Do staticpro for the recently created Q* vars.

	* minibuf.c (read_minibuf): Two additional args histvar and histpos.
	All calls changed.
	(Fcompleting_read): Last arg is now HIST--(HISTVAR . HISTPOS).
	Arg INIT can now be (INITIAL-STRING . INITIAL-POSITION).
	Pass BACKUP_N arg to read_minibuf properly as Lisp object.
	(Fread_from_minibuffer): Likewise.
	(syms_of_minibuf): Set Qminibuffer_history and staticpro it.

	* eval.c (Ffuncall, Feval): Support subrs with 7 args.

	* fns.c (Fyes_or_no_p): Use Fread_string, not read_minibuf.
	* callint.c (Fcall_interactively): For 'S', use Fread_no_blanks_input
	rather than read_minibuf.

1992-07-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* minibuf.c (Vminibuffer_history_variable): New variable.
	(syms_of_minibuf): Define variable minibuffer-history-variable.
	(read_minibuf): Push the string on specified history list.

1992-07-23  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* Makefile.in (doall, doxemacs, dotemacs): Put quotes around CC=${CC}.
	Don't include $(MAKEOVERRIDES); that is always implicit.

1992-07-22  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (read_key_sequence): If we have read a
	meta-character, prefix it with meta_prefix_char before looking it
	up in the function key keymap.

	* lread.c (Fread_char_exclusive): Code this with a do-while loop,
	not a while loop with its body repeated.

	* lread.c (Fread_event): Don't make this function's definition
	conditional on X-windows.  It ought to be there no matter how
	Emacs was built.
	(syms_of_lread): Don't make its defsubr conditional either.

	* lread.c (Fread_char): Doc fix.

	* fileio.c (find_file_handler): It's called
	Vfile_name_handler_alist, not Vfile_handler_alist.
	(Fwrite_region): Declare the variable named `handler'.
	(Fverify_visited_file_modtime): Use `b->filename', not `filename'.
	(Fset_visited_file_modtime): Declare the variable named `handler'.
	* dired.c (Fdirectory_files, Ffile_name_completion): Use
	`dirname', not `filename'.
	(Qfile_attributes): New variable.
	(syms_of_dired): Initialize it.

	* xselect.c (Fx_own_selection): If we're trying to set
	cut-buffer0, and the value is too large for the X server (as
	indicated by the max_request_size member of the X Display), just
	set the buffer to the empty string, and return nil.

1992-07-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* search.c (fast_string_match): New function.
	* fileio.c (find_file_handler): New function.
	(Fcopy_file, Fmake_directory, Fdelete_directory, Fdelete_file):
	(Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
	(Ffile_exists_p, Ffile_executable_p, Ffile_readable_p, Ffile_symlink_p)
	(Ffile_writable_p, Ffile_directory_p, Ffile_accessible_directory_p):
	(Ffile_modes, Fset_file_modes, Ffile_newer_than_file_p):
	(Fwrite_region, Fverify_visited_file_modtime):
	Use find_file_handler; call the handler and return.
	(Finsert_file_contents): Use find_file_handler;
	cannot just return after the handler, but must handle VISIT.
	(syms_of_fileio): Set up Qcopy_file, etc.
	* dired.c (Fdirectory_files, Ffile_name_completion):
	(Ffile_name_all_completions, Ffile_attributes):
	Use find_file_handler; call the handler.
	(syms_of_dired): Set Qfile_attributes, etc.

1992-07-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xselect.c (Fx_own_selection): Initialize val to nil, so that if
	we don't get the selection, we don't return garbage.  When setting
	cut-buffer0, set val to the string pasted.

	* xfns.c (x_set_name): If ARG is nil, set the frame's name to the
	current x_id_name.
	* xdisp.c (display_mode_line): If we should set the frame's name,
	but there is only one frame currently active, call x_set_name with
	nil as the name; this will display samething generically
	appropriate.

1992-07-20  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* lread.c (isfloat_string): Recognize floats without a leading
	integer part, noting that "e5" is a symbol, not a floating point
	number.

	* xdisp.c (message, message1): When displaying a message, don't
	make the minibuf frame visible unless the selected frame is also
	visible.  This means that frames won't pop up unless the user is
	actually interacting with Emacs.

	* xdisp.c (display_mode_line): If Emacs is currently supporting
	only one screen, don't change the title of the screen to the name
	of the current buffer; this is only annoying in this case.  We
	should probably think more carefully about how screens should be
	named.

1992-07-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* process.c (allocate_pty): Handle PTY_OPEN.
	Delete system-specific alternatives to PTY_NAME_SPRINTF
	and PTY_TTY_NAME_SPRINTF.

1992-07-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* callint.c (Fprefix_numeric_value): Fix typo: test raw, not val.

1992-07-17  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xfns.c (x_window): x_set_name normally ignores requests to set
	the name if the requested name is the same as the current name.
	This is the one place where that assumption isn't correct; f->name
	is set, but the X server hasn't been told.  So fake it out.

	* emacs.c [sun] (main): On suns, localtime caches the value of the
	time zone rather than looking it up every time.  This means that
	the dumped Emacs doesn't check the value of the TZ environment
	variable.  Call tzset before entering the editing loop to check
	the new TZ value.

1992-07-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* dired.c (Fdirectory_files): Don't forget to pass the REGP
	argument to compile_pattern.
	* search.c (compile_pattern): If REGP is zero, don't call
	re_set_registers; nobody cares.

	* fileio.c (auto_save_error): Pass the correct number of arguments
	to Fsleep_for.

	* lread.c: Include <ctype.h> at the top of the file, instead of
	just before isfloat_string; read0 wants to use it too.

	* process.c (Fdelete_process, Fprocess_status, Fprocess_send_region,
	Fprocess_send_string, Fprocess_send_eof, Finterrupt_process): Doc
	fixes.

	* process.c (Fprocess_status): Use get_process to find the process
	denoted by the PROC argument, not Fget_process.

1992-07-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xdisp.c: Doc fix.

1992-07-14  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* window.c (syms_of_window): Doc fix for pop-up-frames.

	* frame.c (Fframe_parameters): Note that if FRAME is omitted, it
	defaults to the selected frame.

	* frame.c (Fframe_height, Fframe_width): Blocked out these
	functions; they have no C callers, and can be written nicely in
	lisp.

	* frame.c (Fframe_pixel_size): Function removed; there aren't
	enough other functions available to make this useful.  We need
	functions describing the size of the characters of a font.

	* xterm.h, xterm.c, xselect.c, xmenu.c, xfns.c, xdisp.c, window.h,
	window.c, termopts.h, termhooks.h, termchar.h, term.c sysdep.c,
	scroll.c, screen.c, screen.h, process.c, print.c, minibuf.c,
	lisp.h keyboard.c, indent.c, fns.c, emacs.c, dispnew.c,
	dispextern.h, cm.h, alloc.c, config.h.in: Screens are now called
	frames, to avoid even more confusion with X terminology than
	Emacs's "windows" already cause.  All macros, functions, and
	variables renamed; all uses changed.
	* screen.c, screen.h: Renamed to frame.c and frame.h.  All
	#includers changed.
	* ymakefile: Adjusted appropriately.
	* buffer.c: Doc fixes.

	* xfns.c (Fx_store_cut_buffer): Reversed sense of test for non-X
	screen.

	* window.c (Frecenter): Doc fix; this function places point in the
	middle of the current window, not the current screen.

	* window.c (temp_output_buffer_show): Use WINDOW_SCREEN macro
	instead of accessing the member directly.

1992-07-13  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* print.c (print): Changed code which prints screen objects to use
	the SCREEN_LIVE_P macro instead of testing the screen structure
	directly.

	* alloc.c (undo_threshold, undo_high_threshold): Variables renamed
	to undo_limit and undo_strong_limit.
	(Fgarbage_collect): Uses changed.
	(syms_of_alloc): DEFVARs and docstrings changed.
	* undo.c (truncate_undo_list): Comment adjusted.

	* lread.c (read0): Allow floating-point numbers to begin with a
	period.  `(0 .5)' denotes a list of two numbers, not a dotted pair.

1992-07-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fns.c, callproc.c: Doc fix.

1992-07-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* bytecode.c (Bsymbol_function, Bfset): Removed comments saying
	that these are no longer generated.  Jamie Zawinski's byte
	compiler does generate them, and he's actually collected
	statistics on how often these functions are called.

1992-07-09  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* screen.c (store_screen_param): Clarify error message.

	* xterm.c (x_make_screen_visible): Undo the change made on June
	30; that is not the right solution.  Apparently there are three
	states a window may be in: normal, iconified, and invisible.

1992-07-08  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* eval.c (Fmacroexpand): Code cleaned up; there's no need to
	handle forms like ((macro lambda ...) ...) specially.

	* fileio.c (Finsert_file_contents): Signal an error if we're asked
	to read from a named pipe.

1992-07-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* m/*.h (SIGN_EXTEND_CHAR): Removed these definitions.  The only
	place they were used is in regex.c, and nowadays that has its own
	definition, which works for any machine.  The definitions in the
	machine description files usually didn't work if given an unsigned
	character as an argument, anyway.

1992-07-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* buffer.c: Doc fix.

1992-07-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* minibuf.c (Fdisplay_completion_list): Declared new variables
	used in rms' previous change.

1992-07-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* minibuf.c (Fdisplay_completion_list): Handle non-buffer stream.

1992-07-01  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* window.c (Fdisplay_buffer): Add interactive spec.

1992-06-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* mem_limits.h: EXCEEDS_ELISP_PTR declared here.
	* ralloc.c: No longer declared here.
	* vm-limit.c: Nor here.  Also, include "lisp.h" before
	"mem_limits.h" and additionally include "config.h".

1992-06-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (x_make_screen_visible): Don't de-iconify the window;
	iconification is orthogonal to visibility.

	* emacs.c (syms_of_emacs): Change docstring for `kill-emacs-hook'
	to describe it as a hook, not as a single function.

1992-06-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* minibuf.c (Fread_no_blanks_input): Corrected maximum number of
	arguments from one to two.

	* emacs.c (Vkill_emacs_hook): Declare this here; it should have a
	docstring, so we might as well DEFVAR it.
	(syms_of_emacs): initialize it, and DEFVAR_LISP it with an
	appropriate docstring.

1992-06-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* lread.c (Feval_buffer): Make the DEFUN match the C argument
	list; this takes two optional arguments, not just one.

	* lisp.h (Lisp_Buffer_Local_Value): Comments neatened.

	* data.c (Fset): Fixed conditional which tests whether the cache
	is invalid.  It used to be pretty munged, and would always declare
	the cache invalid for Lisp_Buffer_Local_Value variables.  Now it
	declares the cache invalid if the buffer is wrong (obviously), of

1992-06-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* data.c (Fset): Comments reformatted for readability.

	* xterm.c (last_mouse_movement_time): New variable.
	(note_mouse_position): Set it.
	(XTmouse_position): Return its current value as the position's
	timestamp.

	* keyboard.c (Qvertical_split): Renamed to `vertical-line',
	since the window arrangement is actually referred to as a
	`horizontal split.'
	(make_lispy_event, make_lispy_movement, syms_of_keyboard): Uses
	renamed here.
	keyboard.h (Qvertical_split): Extern declaration changed here.
	window.c (Fcoordinates_in_window_p): Changed this to return
	`vertical-line' at the appropriate times, rather than
	`vertical-split'.

	* window.c (Fcoordinates_in_window_p): Put symbol names in
	opposing single quotes - `vertical-split', for example.

	* fileio.c (Fexpand_file_name): Don't signal an error if USERNAME
	in a "~USERNAME/..." filename isn't a real user; just leave the
	"~USERNAME" unchanged.

	* fileio.c (Fmake_symbolic_link): Rename argument `NEWNAME' to
	`LINKNAME', to conform with the docstring.

	* Makefile.in (CPP): Pass `-Is -Im' to CPP, to make sure that
	machine- and system-dependend files can include each other
	properly.
	* ymakefile (CFLAGS): Add those directories to the #include path
	here too.

	* Makefile.in (xmakefile): Build this via a temporary file, so
	that if preprocessing fails we don't nuke the xmakefile.

	* fileio.c: There are two versions of Fexpand_file_name defined
	here; the latter is inside a `#if 0' clause.  Change its DEFUN to
	a DEAFUN, so that its docstring doesn't make it into the DOC file
	and supercede the real docstring.

	* callint.c (Fcall_interactively): For the 'K' interactive spec,
	set varies[i] to -1, indicating that the mouse click should be
	quoted if the function makes it into the command history, and that
	this argument by itself does not qualify the command to be
	recorded in the history.

1992-06-26  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* data.c (Frem): The drem function will sometimes return a
	negative number.  If it does, add the divisor to it, to make it
	positive.

	* screen.c: Put '#ifdef MULTI_SCREEN' after the inclusion of
	config.h.

	* window.c (Fpos_visible_in_window_p): Remember to apply XSCREEN
	to w->screen before applying SCREEN_WIDTH.

	* screen.h [not MULTI_SCREEN] (last_nonminibuf_screen): Removed
	#definition of this; it's confusing when debugging.
	* screen.c (last_nonminibuf_screen): Variable moved from here...
	* dispnew.c (last_nonminibuf_screen): to here, beside
	selected_screen.  They should both exist, even if the multi-screen
	support is not present.

	* dispnew.c [not MULTI_SCREEN] (the_only_screen): New variable.
	Instead of having the non-multi-screen version of Emacs refer to
	lots of different variables scattered hither and yon, we'll just
	declare this new variable, of type `struct screen', and define the
	single-screen versions of the `SCREEN_foo' macros to reference its
	elements.  This avoids conflicts between names of local variables
	and names of global variables describing the screen, and simplifies
	some of the differences between the multi-screen and single-screen
	cases.
	* screen.h (enum output_method, struct screen): Removed these from
	the `#ifdef MULTI_SCREEN' conditional.
	* screen.h [not MULTI_SCREEN] (the_only_screen): extern
	declaration for it here.
	[not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS, SCREEN_DESIRED_GLYPHS,
	SCREEN_TEMP_GLYPHS, SCREEN_HEIGHT, SCREEN_WIDTH,
	SCREEN_NEW_HEIGHT, SCREEN_NEW_WIDTH, SCREEN_CURSOR_X,
	SCREEN_CURSOR_Y, SCREEN_ROOT_WINDOW, SCREEN_INSERT_COST,
	SCREEN_DELETE_COST, SCREEN_INSERTN_COST, SCREEN_DELETEN_COST,
	SCREEN_MESSAGE_BUF, SCREEN_SCROLL_BOTTOM_VPOS): Macros changed to
	refer to the_only_screen.
	* dispnew.c [not MULTI_SCREEN] (one_screen_cursX,
	one_screen_cursY, one_screen_current_glyphs,
	one_screen_desired_glyphs, one_screen_temp_glyphs,
	delayed_screen_width, delayed_screen_height): Variables
	deleted; they're all now kept in the_only_screen.
	* xdisp.c [not MULTI_SCREEN] (message_buf): Variable deleted; same
	fate.
	* term.c [not MULTI_SCREEN] (one_screen_width, one_screen_height):
	Variables deleted; same fate.
	* screen.h [not MULTI_SCREEN]: extern declarations for the above
	variables removed.
	* window.c [not MULTI_SCREEN] (root_window): Variable deleted.
	[not MULTI_SCREEN] (init_window_once): Use SCREEN_ROOT_WINDOW to
	refer to the root window, instead of referring to it directly.
	* window.h [not MULTI_SCREEN] (root_window): extern declaration
	removed.
	* scroll.c [not MULTI_SCREEN] (insert_line_cost, delete_line_cost,
	insert_n_lines_cost, delete_n_lines_cost): Variables deleted; same
	fate.

	* dispnew.c [not MULTI_SCREEN] (cursX, cursY): Renamed to
	`one_screen_cursX' and `one_screen_cursY'.
	* screen.h [not MULTI_SCREEN] (cursX, cursY, SCREEN_CURSOR_X,
	SCREEN_CURSOR_Y): extern declarations and macros changed
	accordingly.

	* term.c [not MULTI_SCREEN] (screen_width, screen_height): Renamed
	to `one_screen_width' and `one_screen_height', so as not to
	conflict with local variables when referenced by the `SCREEN_foo'
	macros.
	* screen.h [not MULTI_SCREEN] (screen_width, screen_height):
	extern declarations changed accordingly.
	* termchar.h (screen_width, screen_height): extern declarations
	deleted.  Everyone should go through the `SCREEN_foo' macros.
	(SCREEN_WIDTH, SCREEN_HEIGHT): Changed accordingly.

1992-06-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callint.c (Fcall_interactively): When making a copy of the spec
	string, cast the return value of `alloca' to `unsigned char *',
	not `char *', to match the type of `string'.

	* xselect.c (Fx_own_selection): Cast XSTRING (string)->data to a
	char *, so it can be comfortably passed to XStoreBytes.

	* filelock.c (strcpy): Declare this to return char *.

1992-06-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c (current_glyphs, desired_glyphs, temp_glyphs): Renamed
	to have the prefix `one_screen_', so that the screen macros can
	refer to them without conflicting with local variables.
	* screen.h [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS,
	SCREEN_DESIRED_GLYPHS, SCREEN_TEMP_GLYPHS): Changed accordingly.

	* keyboard.c (read_key_sequence): Put the code which restarts the
	key sequence in a `#ifdef MULTI_SCREEN' conditional.

	* screen.h [not MULTI_SCREEN]: Added definitions for
	CHECK_LIVE_SCREEN and SCREEN_FOCUS_SCREEN for the non-multi-screen
	case.

	* screen.h [not MULTI_SCREEN]: The name is
	`SCREEN_MINIBUF_ONLY_P', not `SCREEN_IS_MINIBUF_ONLY'.

	* xdisp.c [not MULTI_SCREEN] (Fredraw_display): Removed definition
	here; the non-multi-screen version is already defined in
	dispnew.c, alongside the multi-screen version.
	(syms_of_xdisp): Don't try to defsubr Sredraw_display; it doesn't
	exist.

	* lread.c (Fread_char_exclusive): Remove this from the `#ifdef
	HAVE_X_WINDOWS' conditional; it is appropriate in any context.

	* eval.c (Fsignal): Put call to TOTALLY_UNBLOCK_INPUT under the
	protection of a `#ifdef HAVE_X_WINDOWS' conditional.

        * keyboard.c (kbd_buffer_get_event): Expect *mouse_position_hook
	to return the timestamp as an unsigned long, not a lisp_Object.
	This matches the change made to `struct input_event'.
	(make_lispy_movement): Change argument TIME to an unsigned long.
	* xterm.c (XTmouse_position): Change TIME argument to a pointer to
	an unsigned long.
	* termhooks.h (mouse_position_hook): Doc fix.
	* term.c (mouse_position_hook): Doc fix.

	* termhooks.h (struct input_event): If MULTI_SCREEN is defined,
	declare the .screen element to be `struct screen *'; otherwise,
	declare it to be `int'.  See the comment in the file for why I've
	done this obviously wrong thing.

	* print.c (printbufidx): Doc fix.
	* xdisp.c (message_buf_print): Doc fix.

	* dispextern.h (message_buf_size): Variable deleted; it's no
	longer used, since the message buffer is always the width of the
	screen.

	* screen.h [not MULTI_SCREEN] (message_buf): Add extern
	declaration for it here.
	(message_buf_print): Added extern declarations here for both the
	MULTI_SCREEN and non-MULTI_SCREEN cases.
	* dispextern.h (message_buf, message_buf_print): Deleted extern
	declaration for these here.  It should never be used directly; it
	should always be used through the SCREEN_MESSAGE_BUF macro.

	* dispnew.c (temp_glyphs): Added back this variable declaration;
	screen.h and various other places referred to this; where did it
	go?
	* screen.h [not MULTI_SCREEN] (temp_glyphs, desired_glyphs,
	current_glyphs): Add extern declarations for these.

	* dispnew.c (cancel_my_columns): Use SCREEN_DESIRED_GLYPHS macro,
	instead of assuming that a SCREEN_PTR is actually a pointer to
	something; it isn't if we're not using any of the screen support.
	Remove the variable `screen', and find the value for
	`desired_glyphs' directly.
	* xdisp.c (echo_area_display): Use the SCREEN_DESIRED_GLYPHS macro
	to find screen's desired cursor position, instead of assuming that
	a SCREEN_PTR is a pointer to something.
	(display_mode_line): Same.
	* window.c (Fpos_visible_in_window_p): Use the SCREEN_WIDTH macro.
	(replace_window): Use the SCREEN_ROOT_WINDOW macro.
	(window_loop): Use the SCREEN_WIDTH macro.

	* dispnew.c (update_screen): Enclose the statement which
	increments `downto' in a `#ifdef HAVE_X_WINDOWS' conditional.

	* screen.h [MULTI_SCREEN and not MULTI_SCREEN] (FOR_EACH_SCREEN):
	New macro.
	* dispnew.c (window_change_signal, do_pending_window_change): Use
	FOR_EACH_SCREEN instead of assuming that Vscreen_list exists.
	* window.h (root_window): Added extern declaration for this.

	* screen.c: Enclose the entire file in a #ifdef MULTI_SCREEN
	conditional.


1992-06-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* window.c (Fset_window_dedicated_p):
	Replaces Fset_window_buffer_dedicated.  Second arg just t or nil.

1992-06-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* syntax.h (SYNTAX, SYNTAX_MATCH, SYNTAX_COMSTART_FIRST, etc.)
	Cast character to unsigned char before indexing.

1992-06-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (x_wm_set_size_hint): Set size_hints.flags to indicate
	that we are providing the base_width and base_height data.

	* xfns.c (Fx_create_screen): Default the internal border width to
	2; this matches XTerm.

	* syntax.c (Fparse_partial_sexp): Doc fix.

	* syntax.c (Fparse_partial_sexp): Added phony argument list to
	comment containing the docstring for this function, so that
	make-docfile.c will get the right arguments.

	* xfns.c (x_set_name): Don't go through the X11 brouhaha to set
	the name unless we're actually setting it to something different
	from the current name.

1992-06-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* eval.c (syms_of_eval): Don't forget to escape the ends of the
	lines in the docstring for `debug-on-quit'.

	* keyboard.c (Fread_key_sequence): Reversed sense of CONTINUE_ECHO
	argument - set this_command_key_count to zero iff CONTINUE_ECHO is
	Qnil, not iff it's non-Qnil.

1992-06-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* search.c: Changed to remember the object in which the last
	search was done, so that markers from match data are placed in
	that buffer, instead of the current buffer.
	(search_regs_from_string): Replaced with...
	(last_thing_searched): This is either Qnil, meaning no searching
	has been done, Qt, meaning that the last search was done in a
	string, or a buffer object, meaning that the last search was done
	in that buffer.
	(syms_of_search): Initialize and staticpro last_thing_searched.
	(Flooking_at, search_buffer): Set last_thing_searched to the
	current buffer.
	(Fstring_match): Set last_thing_searched to Qt.
	(Fmatch_data): Test last_thing_searched to see if any searching
	has been done, and construct integers or markers in the right
	buffer.  Abort if it's not Qt, Qnil, or a buffer.
	(Fstore_match_data): Set last_thing_searched according to the
	things we find in LIST.

1992-06-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* fns.c (Fload_average): Document the fact that this sometimes
	returns a list of fewer than three elements, on systems which
	don't provide 5- and 15-minute load averages.

1992-06-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (XTread_socket): If an event arrives to a screen S,
	don't attribute them to SCREEN_FOCUS_SCREEN (S) here.  Do that
	synchronously, when the events are dequeued.  This keeps events
	from being accidentally routed to the wrong screen, if we
	temporarily redirect a screen's focus.
	* keyboard.c (kbd_buffer_store_event): If the character being
	stuffed is a quit character, do the SCREEN_FOCUS_SCREEN
	redirection to it here.
	(kbd_buffer_get_event): And do it here, before returning the
	event.

	* eval.c (Finteractive_p): This assumed that if the function in
	the top frame of the lisp backtrace was not a Lisp_Compiled
	object, then Finteractive_p must have an explicit frame on the top
	of the stack, which we could skip.  It didn't bother to follow the
	symbol function chaining, and it would break if any C code called
	from a non-compiled function tried to call Finteractive_p anyway.
	Changed this to actually check if the top frame's effective
	function is the Lisp_Subr for Finteractive_p.  This also used to
	skip any number of frames for special forms and/or Fbytecode
	calls.  Changed this to skip an Fbytecode frame (if present),
	followed by any number of special form frames.

1992-06-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* eval.c (struct backtrace): Doc fix.

1992-06-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* m/hp300bsd.h (LOAD_AVE_TYPE): This is long, not double.
	(LOAD_AVE_CVT): Adjusted as appropriate.

	* fns.c: Moved lots of system-dependent preprocessor cruft
	dealing with getting the load average to `getloadavg.c'.
	(Fload_average): Guts moved to `getloadavg.c'.
	* getloadavg.c: New file, containing the necessary mess to get the
	load average on many different systems.  This file is supposed to
	be Emacs-independent.
	* ymakefile (obj): Add getloadavg.o to the list.
	(getloadavg.o): Note that this depends on its source, and config.h.

	* screen.c (Fdelete_screen): Typo in loop looking for new
	last_nonminibuf_screen - change	`screen = XCONS (screens)->cdr`
                                     to	`screens = XCONS (screens)->cdr`

	* xdisp.c (echo_area_display): Don't neglect to draw all the lines
	of the minibuffer window (or echo area) when a message is being
	displayed.  If the minibuffer is more than one line high, they
	should all be blanked.

1992-06-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* sysdep.c [POSIX_SIGNALS] (sys_signal): Fix typo - rather than
	calling new_action as if it were a function, call sigaction.

1992-06-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* lisp.h (Qnumberp, Qnumber_or_marker_p): Declared.

	* eval.c (wants_debugger): Changed NULL to NILP.
	Who installed these calls to NULL?

1992-06-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c (Fsit_for): Don't forget to actually set sec from ARG.

	* termhooks.h (struct input_event): Doc fix - for mouse clicks, .x
	and .y give the position in characters, not in pixels.

	* keyboard.c (format_modifiers): Order the modifier letters
	alphabetically - control, meta, shift, and up.

1992-06-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* xfns.c: Move some extern decls out of #if 0, to top of file.

1992-06-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* window.c (Fcoordinates_in_window_p): Docstring fix.

	* buffer.c (Fother_buffer): Put a comma between arguments BUFFER
	and VISIBLE_OK in the argument list.  Duh.

	* screen.c (Fdelete_screen): Remember that s is a SCREEN_PTR *,
	not a Lisp_Object.

	* search.c (search_regs): Doc fix.
	(compile_pattern): Take a new argument - the search register
	structure - so we can reassure the regex routines that the
	registers have been allocated.
	(Flooking_at, Fstring_match, search_buffer): Changed to pass
	&search_regs to compile_pattern.
	(search_buffer): When we've searched for a literal string and
	found it, make sure that the search registers are allocated before
	stuffing the location of the search into them.
	(Fstore_match_data): If we need to allocate more registers,
	allocate them using re_set_registers, instead of just storing the
	new registers and hoping that regex doesn't free them.

	* search.c (Freplace_match): Doc fix.

1992-06-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* screen.c (Fdeiconify_screen): Function deleted.
	It was the same as make-screen-visible.

1992-06-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c: Doc fix.

	* floatfns.c (Fcbrt): Renamed from Fcube_root, and #if 0'd.

	* lisp.h (CHECK_NUMBER_OR_FLOAT*): Use Qnumberp or Qnumber_or_marker_p.
	* data.c (syms_of_data): Staticpro those.
	(Qinteger_or_float_p, Qinteger_or_float_or_marker_p): Deleted.
	(Fnumberp, Fnumber_or_marker_p): Define these always,
	but make them work even if not LISP_FLOAT_TYPE.

1992-06-05  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* config.h.in: Undefine REL_ALLOC if a system specific file
	defines SYSTEM_MALLOC.

	* sysdep.c (save_signal_handlers): Cast result of signal  to
	avoid compiler warning.
	* process.c (send_process): Likewise.

1992-06-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (Fread_key_sequence): New 2nd arg CONTINUE_ECHO
	added for the sake of universal-argument.

1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* editfns.c (Fset_default_file_mode): Function deleted.
	(Funix_sync): Moved.
	* fileio.c (Funix_sync): Moved to here.

	* xfns.c (Fx_erase_rectangle, Fx_draw_rectangle, Fx_contour_region):
	(Fx_uncontour_region): #if 0 these.
	(x_rectangle, outline_region): Likewise.
	(syms_of_xfns): #if 0 the defsubrs.

	* dispnew.c (Fsleep_for, Fsit_for): Clean up error messages.

	* eval.c, print.c, keyboard.c: Doc fix.

	* xfns.c (Fx_horizontal_line): Disabled, since not documented.

	* fileio.c (Fdelete_directory): Renamed from Fremove_directory.

	* unexencap.c: Deinstalled (renamed to =unexencap.c)
	since awaited papers never arrived.

	* xfns.c: Doc fix.

1992-06-04  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

	* eval.c (stack_trace_on_error, debug_on_error): Made Lisp_Objects V*.
	(syms_of_eval): Changed DEFVAR_BOOLs to DEFVAR_LISPs.
	(wants_debugger): New fn.
	(find_handler_clause): Use it to look in debug-on-error and
	stack-trace-on-error lists.

1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* floatfns.c (Fbessel_*, Ferf, Ferfc, Flog_gamma): Turned off;
	not clearly worth including.
	(Fasinh, Facosh, Fatanh, Fsinh, Fcosh, Ftanh): Likewise.

1992-06-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* minibuf.c, keyboard.c: Doc fix.

	* window.c (Fwindow_at): Fix number of args--minimum 2, max 3.

	* screen.c: Doc fix.

1992-06-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* lread.c (Feval_buffer): Don't read any arguments, if interactive.

1992-06-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* screen.c (make_screen_without_minibuffer): Apply XSCREEN to
	Vdefault_minibuffer_screen before calling SCREEN_LIVE_P.  The
	argument to SCREEN_LIVE_P must be a SCREEN_PTR, not a Lisp_Object.

	* dispnew.c (Fsit_for): This used to compare arg with 0 and return
	Qt immediately.  It should actually call sit_for anyway, because
	sit_for needs to test for input and do the redisplay.
	(sit_for): Compare sec and usec with zero here, after we've
	looked for input and done a redisplay.

	* lread.c (Feval_buffer): Use NILP, not NIL_P.

1992-06-01  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* buffer.h: New macro, BUF_SET_PT.

	* lread.c: New subr `eval-buffer', replaces `eval-current-buffer',
	which is now defined in simple.el.

1992-05-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* screen.c (Fdelete_screen): If we're deleting the default
	minibuffer screen, try to find another minibuffer screen.

1992-05-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* buffer.c (Fother_buffer): New optional argument VISIBLE_OK,
	indicating that buffers currently visible in windows should not be
	discriminated against.

1992-05-28  Ken Raeburn  (raeburn@cygnus.com)

	* screen.c (Fdelete_screen): Fix bugs in walking screen list.
	(make_screen_without_minibuffer): Signal an error if the default
	minibuffer screen is dead.

	* xfns.c (x_set_name): Use ICCCM-conforming scheme for changing
	window name in X11.
	(Fx_create_screen): Likewise.

1992-05-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xselect.c: Support getting and setting the obsolete X cut
	buffers.
	(Qcut_buffer0): New atom, denoting the X cut buffer 0.
	(syms_of_xselect): Initialize and staticpro it.
	(Fx_own_selection): If TYPE is Qcut_buffer0, interpret this to
	mean that we should set cut buffer 0 to STRING.
	(Fx_selection_value): If TYPE is Qcut_buffer0, interpret this to
	mean that we should retrieve the value of cut buffer 0.

1992-05-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (construct_mouse_click): Removed extra assignment of
	result->timestamp.

	* keyboard.c (last_event_timestamp): Doc fix.
	* xselect.c (last_event_timestamp): Declare it extern here.
	(mouse_timestamp): Variable deleted.  last_event_timestamp is a
	more accurate thing to use here.
	(own_selection, get_selection_value): Use last_event_timestamp
	instead of mouse_timestamp.
	* keyboard.c (make_lispy_event): Pass the event's timestamp
	through the make_number function, to assure that it is properly
	tagged before incorporating it into the lispy event.
	* xterm.c (construct_mouse_click): The timestamp element of a
	struct input_event is no longer a Lisp_Object; it is now an
	unsigned long.  So don't use XSET to assign to it.
	(XTread_socket): Same here, in processing KeyPress events.

	* keyboard.c (Fexecute_extended_command): Properly initialize
	this_command_keys to the concatenation of the sequence that
	invoked Fexecute_extended_command, the characters making up the
	name of the command we're running, and a return character.
	Previously, this code would set it to the last key typed while
	reading the function name from the minibuffer, followed by the
	name of the function being run.

1992-05-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (x_display_box_cursor): Draw the cursor at curs_{x,y},
	rather than at s->cursor_{x,y}.  If cursor_in_echo_area is set,
	then s->cursor_{x,y} does not accurately describe the position of
	the cursor.  However, if we're not updating, then curs_{x,y} are
	garbage; set them from s->cursor_{x,y}.

	* dispnew.c (update_screen): Check current_screen->enable and
	current_screen_used to see if there is any text on the last line,
	not desired_screen->{enable,used}.  When the line isn't enabled,
	move to line SCREEN_HEIGHT (s) - 1, not SCREEN_HEIGHT (s).
	Rearranged conditionals.

	* dispnew.c (cursor_in_echo_area): Document the interpretations of
	positive and negative values of this variable.

1992-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* dispnew.c (Fding): If have arg, don't end a keyboard macro.

1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c (sit_for): New function, which is a slight
	generalization of Fsit_for; you can tell it that it's waiting for
	input, so C-g gets handled properly.
	(Fsit_for): Call it, instead of replicating all its guts.
	* keyboard.c (read_char): Call sit_for instead of Fsit_for, and
	indicate that we're awaiting keyboard input.

	* dispnew.c (Fsit_for): Rename arguments to match docstring.  Use
	NILP instead of EQ (foo, Qnil).	 If nodisp is non-nil, call
	wait_reading_process_input with do_display 0, instead of 1; this
	will inhibit spurious redisplays when process input arrives during
	a sit-for.

        * process.c (Faccept_process_output): Pass zero as read_kbd
	argument to wait_reading_process_input when PROC is nil, not when
	PROC is non-nil.

	* process.c (wait_reading_process_input): Declare read_kbd to be a
	Lisp_Object, and use the tagging to tell the difference between a
	process object and an integer.
	* dispnew.c (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Pass
	read_kbd argument to wait_reading_process_input as a Lisp_Object.
	* keyboard.c (kbd_buffer_get_event): Same.
	* process.c (Faccept_process_output, send_process): Same.

	* keyboard.c (read_char): Use save_getcjmp and restore_getcjmp
	instead of doing the bcopy explicitly.

	* xterm.c (XTread_socket): When handling an EnterWindow event,
	don't bother to check waiting_for_input.  It's not necessary.

	* keyboard.c (read_char): Don't clear waiting_for_input and
	input_available_clear_time here.
	(quit_throw_to_read_char): It's already done here.

	* keyboard.c (quit_throw_to_read_char): Use
	clear_waiting_for_input instead of clearing waiting_for_input
	explicitly.

1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (read_char): Call clear_waiting_for_input instead of
	clearing waiting_for_input and input_available_clear_time
	explicitly.

1992-05-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ymakefile [defined (__GNUC__) and __GNUC__ > 1]: define
	YMF_PASS_LDFLAGS so that it can deal with an empty flags argument.

	* callproc.c (Fcall_process): Under VMS, a nil INFILE argument
	means to read from "NLA0:", not "/dev/null".

	* callproc.c (Fcall_process): Use nil as the value for display
	(the fourth argument) when nargs >= 4, not when nargs >= 3.

1992-05-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* termhooks.h: Change timestamp from a Lisp_Object to an unsigned
        long.
	* keyboard.c (kbd_buffer_store_event): We don't have to apply the
        XINT macro to the timestamp member of the event anymore.

	* process.c (wait_reading_process_output): Don't turn off polling.

	* sysdep.c (setpgrp_of_tty): Pass the address of pid, not pid
	itself.

	* process.c: Deleted cpp tangle for dealing with system-dependent
	tty handling; #included "systerm.h".
	* systerm.h: Add some of the things that were done in process.c:
	If titan is #defined, then we should include <sys/ttyhw.h> and
	<sys/stream.h> along with the other SYSV pty stuff.
	If HPUX is #defined, then EMACS_HAVE_TTY_PGRP isn't true.
	If XENIX is #defined, then we shouldn't try to use TIOCGETC.
	* ymakefile: Note that process.o depends on systerm.h now.

1992-05-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * callint.c (Fprefix_numeric_value): Value 1 for symbol other than `-'.

1992-05-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* cmds.c (Fforward_line): If the buffer is empty, don't try to see
	if it contains a newline, and moving nowhere at eob after
	non-newline should return 1, not 0.

	* search.c (scan_buffer): Doc fix.

	* buffer.c (Fbuffer_disable_undo): Accept a buffer name as an
	argument.

1992-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c: Include config.h first thing.

	* keyboard.c (clear_input_pending): New subroutine.
	* process.c (wait_reading_process_input): Make C-g really quit in
	sit-for case.

        * ymakefile (LD_SWITCH_SYSTEM): Don't use -X with GCC.

1992-05-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* eval.c (Fapply): Use indirect_function, instead of doing a dumb
	loop.
	* keymap.c (get_keymap_1): Same.
	* macros.c (Fexecute_kbd_macro): Same.

	* buffer.c (init_buffer_once): Don't disable undos for *scratch*
	here.  Do it in loadup.el.

	* buffer.c (init_buffer_once): Doc fix.

	* doc.c (Fdocumentation): After extracting the doc string from a
	lambda or autoload expression, don't fall through to the default
	case and signal an invalid function error; instead, do a `break'.

	* doc.c (Fdocumentation): Use EQ (x, y) instead of XSYMBOL (x) ==
	XSYMBOL (y).

	* doc.c (Fdocumentation): When decyphering a function made from
	conses, use 'else if' for the chain of alternatives instead of
	just 'if'.  It used to be that each alternative returned, but
	that's not true anymore.

	* alloc.c (Fgarbage_collect): Don't call truncate_undo_list on
	buffers whose undo list is 't.

	* doc.c (Fdocumentation): Renamed argument `fun1' to `function',
	so make-docstring will list argument consistently with the
	docstring.

1992-05-11  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

	* xterm.h: Removed definition of `RES_CLASS'.

	* xfns.c (x_get_arg): Eliminated `screen_name' parameter.  No
	longer uses screen name as X resource search component.
	All calls to x_get_arg changed accordingly.
	Global variable `screen_class' and #define `SCREEN_CLASS' removed.

	* xterm.c (XTread_socket): Added basic structure for handling
	various ClientMessage events, using new global variables
	`Xatom_wm_take_focus', `Xatom_wm_save_yourself',
	`Xatom_wm_delete_window', `Xatom_wm_configure_denied',
	`Xatom_wm_moved'.
	* xfns.c: Declare these variables extern.
	(syms_of_xfns): Initialize these variables.

	* xselect.c (Fx_own_selection, Fx_selection_value): New optional
	parameter `type', to specify the selection type.
	(syms_of_xselect): New symbols Qprimary, Qsecondary, Qclipboard
	initialized.

1992-05-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* data.c (Qcyclic_function_indirection): New error condition.
	(indirect_function, Findirect_function): New functions.
	(syms_of_data): Initialize Qcyclic_function_indirection, put the
	error properties on it, and staticpro it.  Defsubr
	Findirect_function.
	* lisp.h (indirect_function, Findirect_function): Declare them here.
	* callint.c (Fcall_interactively): Get symbol's function by
	calling indirect_function, instead of just looping.
	* doc.c (Fdocumentation): Same.
	* eval.c (Finteractive_p, Fcommandp, do_autoload, Feval,
	Ffuncall): Same.
	* keyboard.c (Fcommand_execute): Same.

	* data.c (Fsymbol_function): Name the argument `symbol' instead of
	`sym', so make-docstring will list argument consistently with the
	docstring.

	* process.c (wait_reading_process_input): Make sure the screen
	isn't garbaged (and therefore not displayed) before we enter the
	select and start waiting for input.

	* keyboard.c: #include <systime.h>.
	* ymakefile (keyboard.o): This depends on systime.h.
	* keyboard.c (input_available_clear_word): Replaced with
	input_available_clear_time, which is a pointer to an EMACSTIME;
	sometimes the time information is larger than a single word.
	(read_char): Changed ..._word to ..._time.
	(input_available_signal): Use the EMACS_SET_SECS_USECS macro to
	clear *input_available_clear_time, instead of zapping a zero into
	*input_available_clear_word.
	(set_waiting_for_input, clear_waiting_for_input): Adjusted
	appropriately.

1992-05-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* editfns.c (make_buffer_string): New function.
	* lisp.h (make_buffer_string): Declare it here.
	* editfns.c (Fbuffer_substring): Call make_buffer_string instead
	of writing it out.
	(Fbuffer_string): Call make_buffer_string instead of make_string,
	so we can deal with buffer relocations.
	* minibuf.c (read_minibuf): Same here.

1992-05-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* syssignal.h (sigunblock): New macro, taken from 18.58's
	emacssignal.h file.
	* sysdep.c (request_sigio): Use the sigunblock macro to enable
	reciept of SIGWINCH, instead of the dysfunctional sigblockx.

1992-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* search.c: Doc fix.

1992-05-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* emacs.c (decode_env_path): If EVARNAME is zero, don't try to
	call getenv on it.
	* lread.c (init_lread): When we don't have an environment variable
	to check, pass 0 instead of the empty string.

	* alloc.c (Fmake_marker): Use `SIGMASKTYPE' instead of `int'.
	Instead of calling sigsetmask twice - once to get the mask, and
	again to restore it - call sigblock, specifying no additional
	signals.

1992-05-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* alloc.c: #include <syssignal.h>, for the sake of the
	bug-catching code in Fmake_marker.
	ymakefile: Add dependency.

	* syssignal.h [not POSIX_SIGNALS] (SIGFULLMASK): New definition,
	for symmetry with the "defined (POSIX_SIGNALS)" case.

	* callproc.c (child_setup): Since we always get the environment
	from Vprocess_environment, don't bother to take the environment
	the subprocess should inherit as an argument anymore.
	* process.c (create_process): Don't pass environment as a
	variable.  Just preserve it across call to fork.

1992-05-04  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* floatfns.c: #include <syssignal.h>.
	(float_error): Use SIGEMPTYMASK instead of zero.

	* syssignal.h [POSIX_SIGNALS] (sigmask): Defined to expand to a
	statement expression under GCC, or a function call otherwise.
	(sigpause, sigblock, sigunblock, sigsetmask): These are now
	K&R-compatible macros.
	* systerm.h [POSIX_SIGNALS] (sys_sigmask): Here is the function
	the POSIX version of sigmask calls when we're not compiling with
	GCC.
	* alloc.c (Fmake_marker): Undo changes of Apr 29.
	* callproc.c (Fcall_process): Same.
	* data.c (arith_error): Same.
	* floatfns.c (float_error): Same.
	* keyboard.c (gobble_input): Same.

	* sysdep.c (request_sigio, unrequest_sigio)

1992-04-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* x11term.h (CLASS): Change this from "emacs" to "Emacs"; class
	names should always start with an upper-case letter.

	* syssignal.h: Arranged cpp conditionals so that the specific
	cases come first, generic cases last.

	* syssignal.h (sigpause, sigblock, sigunblock, sigsetmask): Macros
	removed; they require GCC, and Emacs 19 should compile without GCC.
	(EMACS_SIGPAUSE, EMACS_SIGBLOCK, EMACS_SIGUNBLOCK,
	EMACS_SIGSETMASK, EMACS_SIGFREE, EMACS_SIGHOLDX, EMACS_SIGBLOCKX,
	EMACS_SIGUNBLOCKX, EMACS_SIGPAUSEX): These are new macros that
	don't require GCC, but expand to statements.
	* callproc.c (Fcall_process): Use new EMACS_SIG* macros from
	syssignal.h.
	* keyboard.c (gobble_input): Same.
	* sysdep.c (request_sigio, unrequest_sigio): Same.
	* x11term.h (BLOCK_INPUT, UNBLOCK_INPUT): Same.
	* alloc.c (Fmake_marker): Same.
	* data.c (arith_error): Same.
	* floatfns.c (float_error): Same.

1992-04-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ymakefile: If we're using GCC version 2.0 or later, use "$(CC)
	-nostdlib" as the linker.  This will allow us to find libgcc.a
	even when GCC puts it in a really weird place.
	(YMF_PASS_LDFLAGS): New macro.
	(temacs): Use it.

	* s/hpux.h: Doc fix.

	* filelock.c (egetenv): Declare this.
	(lock_path, SUPERLOCK_NAME, superlock_path): New variables and
	macros.
	(MAKE_LOCK_PATH, lock_file, unlock_file, lock_superlock): Use the
	variables lock_path and superlock_path instead of the PATH_LOCK
	and PATH_SUPERLOCK macros.
	(init_filelock): New function.
	* emacs.c (main): Call the init_filelock function.
	* paths.h.in (PATH_SUPERLOCK): Removed.  This is now calculated
	from PATH_LOCK or from the EMACSLOCKDIR environment variable.

	* filelock.c (MAKE_LOCK_PATH): New macro.
	(lock_file, unlock_file, Ffile_locked_p): Use it.

	* syntax.c (Fmodify_syntax_entry): Note that '-' is a synonym for
	' ' (both denote whitespace), that '\\' denotes the escape class,
	and that '/' denotes the character-quote class.  The description
	used to claim that '\\' denoted the character-quote class, and
	neglected to mention '-' and '/'.

	* filelock.c (lock_file): Doc fix.

1992-04-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callproc.c (init_callproc): Get the default Vexec_path from the
	environment variable "EMACSPATH"; get Vdata_directory from
	"EMACSDATA".

	* ymakefile: Fix #endif and #else comments.

1992-04-27  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* ymakefile (xemacs): Link xemacs to temacs if HAVE_SHM.

	* ymakefile (paths.h, config.h): Never copy, always fail.

	* process.c (wait_reading_process_input): Redisplay if screen_garbaged.
	Call do_pending_window_change first.
	Include dispextern.h.
	* ymakefile (process.o): Added dependency.

	* ymakefile (OLDXMENU_OPTIONS): New macro, used compiling oldxmenu.

1992-04-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ymakefile: Changed all references to LD_CMD to LINKER, for
	compatibility with the 18.58 configuration files.
	* s/aix3-1.h, s/sunos4shr.h: Same here.

	* ymakefile: Doc fixes.

	* ymakefile (CC, MAKE): Set these variables from optional macros.
	Change all uses of `make' to ${MAKE}.

	* ymakefile: use HAVE_X11 as alias for X11.

	* ymakefile (LIB_GCC, GNULIB_VAR): Handle GCC 2.

	* process.c (allocate_pty): Re-arranged conditionals to put the
	system-specific-case first, and the generic case in the #else
	section, for consistency with the rest of Emacs.

	* process.c (allocate_pty): Wait until we fail to open three ptys
	in a row before concluding that we've reached the end of the ptys.

1992-04-22  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ralloc.c: #include "getpagesize.h".

	* search.c (Flooking_at): Use search_regs.num_regs instead of
	RE_NREGS.  As of regex version 0.4, the compiler allocates the
	registers, and may allocate more than RE_NREGS.
	(search_buffer): Same.
	(Freplace_match): Use search_regs.num_regs to tell how many
	registers are valid.  Also note that if none are valid, no search
	has been performed.
	(match_limit): Same.
	(Fmatch_data): Same.
	(Fstore_match_data): If we're trying to store more registers than
	search_regs has allocated, re-allocate them to make room.

1992-04-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)


	* callproc.c (egetenv): Declare the type of VAR.

	* lisp.h: Don't undefine NULL.  There is no longer any conflict.

	* lisp.h (NUMBERP): New macro.
	* editfns.c (Fformat): Protect the sections that deal with
	Lisp_Float objects with a "#ifdef LISP_FLOAT_TYPE".
	* bytecode.c (Fbyte_code): Use the NUMBERP macro instead of
	explicitly checking for the Lisp_Float tag.
	* callint.c (Fcall_interactively): Same here.

	* xrdb.c (magic_searchpath_decoder): Re-allocate string as needed,
	rather than making it a fixed-size array.

	* xfns.c (Fx_rebind_key): Don't declare modifier_list to be a
	register variable.  It's too big, and we need the address of its
	first element when we pass it to XRebindKeysym anyway.

	* fileio.c (Fdo_auto_save): Doc fix.

1992-04-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* search.c (search_buffer): Cast RE_EXACTN_VALUE to char, because
	the regex-0.4 distribution says so.

	* ymakefile (dired.o): This depends on regex.h.

	* process.c (wait_reading_process_input): There is code here which
	sends SIGIO to Emacs if we thought we had input available but
	didn't get SIGIO.  If the system doesn't have SIGIO, then
	#ifdef it out.

	* print.c (Fexternal_debugging_output): Arguments were declared
	ANSI-style - rewritten in K&R 1 fashion.

	* floatfns.c (IN_FLOAT): Cast the zero in the `else' clause of the
	conditional expression to SIGTYPE, to match the type of the
	float_error call in the `then' clause.

	* s/hpux8.h: #define HPUX8; this is supposed to be customary
	procedure, and fileio.c was expecting it, but somehow it didn't
	get defined.

	* sysdep.h: Move inclusions of [AIX] <sys/hft.h>,
	<sys/devinfo.h>, <sys/pty.h>, <unistd.h> [NEED_BSDTTY]
	<sys/bsdtty.h>, [HPUX and HAVE_PTYS] <sys/ptyio.h>, [SYSV_PTYS]
	<sys/tty.h>, <sys/pty.h>, and [pfa] <sys/file.h> to systerm.h;
	also move undefinition of LLITOUT under BSD4_1 to systerm.h.
	* systerm.h: They're here.

	* xterm.c (XTcursor_to, XTclear_end_of_line): Declare to return
	int in the function definitions as well as their declarations.

1992-04-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* fileio.c (directory_file_name): When checking if the string ends
	with '/', check that slen is a valid length *before* examining
	dst[slen-1], not after.

1992-04-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* xterm.c (x_death_handler): New function.
	(x_error_handler): Call x_death_handler to shut down Emacs.
	(x_term_init): Use x_death_handler to handle SIGPIPE, instead of
	x_error_handler, which expects to be passed a display and an
	event.
	* process.c (send_process): This used to set a handler to
	catch SIGPIPEs when writing to a subprocess, and then set the
	handler to SIGDFL after writing, but this would stomp on the
	SIGPIPE handler for for the X connection.  So restore the prevous
	handler instead of changing to SIGDFL.

1992-04-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* indent.c (compute_motion): Fix skipping invis lines and
	truncation at right margin.

1992-04-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* s/hpux.h (PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF): Use pty_name,
	not ptyname.
	* s/rtu.h: Same.

	* process.c (pty_process): Add 'int' to the declaration 'static
	pty_processes;'.  This makes it a happy declaration even when
	static has been #defined as the empty string.
	* xterm.c (XTcursor_to, XTclear_end_of_line): Same.

	* unexec.c (sbrk): Declare this to return void * if __STDC__ is
	defined, or char * otherwise.

	* lread.c (init_lread): Re-cleaned logic.  To determine whether the
	load path was changed before dumping, cons up a dump path and
	compare it.  This method is more localized and accurate.
	(initial_path): Variable removed.
	(syms_of_lread): Don't staticpro.

	* floatfns.c (float_error): Declare and define this to return
	SIGTYPE.

	* systime.h [HAVE_TIMEVAL] (EMACS_GET_TIME): Declare dummy to be a
	real struct timezone, instead of an EMACS_TIME.  Since
	HAVE_TIMEVAL is defined, struct timezone ought to be declared, so
	there's no harm in passing the genuine article.

	* sysdep.c [USG] (rename): Place under the protection of a new
	preprocessor symbol, HAVE_RENAME.
	* s/hpux.h (HAVE_RENAME): Defined.

	* sysdep.c [USG] (setpriority): Declare to return int, not void.

	* s/template.h: Add template section for HAVE_TERMIOS.

	* term.c (cursor_to, raw_cursor_to, fatal): Do declare the types
	of the arguments.

1992-04-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callint.c (Fcall_interactively): When the interactive spec is
	a string, it may be relocated while reading the arguments.  To
	avoid this, make a copy of the spec to refer to, instead of
	using a pointer to the data of the spec string.

	* callint.c (Fcall_interactively): When following the function
	chain of a symbol, check for quits.

1992-04-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* lread.c (init_lread): Make the load path default to
	PATH_LOADSEARCH when we're not dumping (null purify-flag), and
	PATH_DUMPLOADSEARCH when we are (not (null (purify-flag))).
	Change from April 7th incorrectly always used PATH_DUMPLOADSEARCH.

	* lread.c (init_lread): Cleaned up logic; to determine whether the
	load path was changed before dumping, remember the initial value
	and compare against it.
	(initial_path): New variable to support this.
	(syms_of_lread): staticpro initial_path.

	* ymakefile: Renamed filenames like "*-dist" to "*.in".

	* config.h.in: Doc fixes.

1992-04-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* config.h-dist: Renamed to config.h.in, for consistency with
	the installation conventions of other GNU programs.
	* paths.h-dist: Renamed to paths.h.in.

1992-04-11  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)

	* termcap.c: Declare getenv.

1992-04-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* Makefile: Renamed to Makefile.in; the configure script will edit
	this to produce Makefile.

1992-04-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* paths.h-dist (PATH_DUMPLOADSEARCH): New macro.
	* lread.c (init_lread): If we're building an Emacs to be dumped,
	use PATH_DUMPLOADSEARCH as the default load path, so we can
	correctly find our lisp files.

	* config.h-dist, paths.h-dist: Added "-*- C -*-" to top lines, so
	Emacs will know that these are really C source.

1992-04-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* search.c (syms_of_search): When allocating memory
	searchbuf.buffer, cast the return value of malloc to unsigned char
	*, not char *; this changed in the most recent version of the
	regex code.

1992-03-31  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* doc.c (Fdocumentation): Don't forget to end each line of the
	docstring with "\n\".

	* process.c (Fprocess_connection): Change "#ifdef 0" around this
	function to "#if 0".

	* eval.c (Flet, FletX): Signal an error if one of the let's binding
	clauses has more than one value form, as in (let ((a 1 2)) a).

	* eval.c (Ffuncall): Re-install change of March 10; I don't know
	why it went away.

	* search.c (compile_pattern): Declare the variable which holds the
	return value of re_compile_pattern to be const, if this is ANSI C.

	* alloc.c (xrealloc): Change "ese" to "else".

	* crt0.c (start1) [sun_soft]: Change 'jst' to 'jsr'.  The Sun
	assembly language manual doesn't list any 'jst' instruction, I
	don't know of one personally, and all the analogous code
	around it uses 'jsr'.

	* crt0.c [m68k]: Merged with GNU C Library's version: added
	conditionals for sun_68881, sun_fpa, sun_soft.

	* config.h-dist: Adjusted for renaming of share-lib to etc.
	* lread.c (read1): Same.
	* doc.c (Fdocumentation_property, Fsnarf_documentation): Same.
	* ymakefile: Same.

1992-03-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* crt0.c: Merged changes from 18.58:
	[hp9000s300]: Set flag_fpa.  Define float_loc.
	[new hp assembler]: Double flag_fpa and flag_68881 if %d2!=0.
	(start1): Declare to be static at the top of the file.
	(_start): Removed static declaration in this function; since
	everyone wants it, we'll just put it here.

1992-03-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c (Finsert_file_contents): Allow quitting from I/O.
	(Fcopy_file): Likewise.

1992-03-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* m-intel386.h (HAVE_ALLOCA): Inhibit if C_ALLOCA.
	(LIB_STANDARD): Alternate USG value if __GNUC__ or C_ALLOCA

	* alloc.c (xrealloc): If handed a NULL pointer for the block to
	resize, malloc a new block and return that.  Not all reallocs do
	this.

	* m/elxsi.h: Doc fix.

1992-03-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* dispnew.c (Fsleep_for): Call wait_reading_process_input, whether
	or not we have process support; let the emulator do the work.
	* emacs.c (fatal_error_signal, Fkill_emacs): Call
	kill_buffer_processes even when subprocesses is not #defined; we
	have a stub.

	* process.c [not defined (subprocesses)] (Fget_buffer_process,
	init_process, syms_of_process): New stub versions of these functions.
	* emacs.c (main): Call init_process and syms_of_process whether or
	not subprocesses is #defined.
	* xdisp.c (decode_mode_spec): Call Fget_buffer_process whether or
	not subprocesses is #defined.

1992-03-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (kbd_buffer_get_event): Call
	wait_reading_process_input, even when subprocesses is not
	#defined, instead of doing a whole lot of hairy SIGIO-pausing
	stuff.
	* dispnew.c (Fsit_for): Call wait_reading_process_input, whether
	or not subprocesses is #defined.

	* process.c (wait_reading_process_input): Since we're no longer
	checking for exceptional conditions in the call to select, all of
	the different ways to call select for different systems have
	become the same; remove the #if conditionals around this.

	* keyboard.c (read_char): When returning quit_char because we got
	an interrupt signal, claim that the character came from the
	currently selected screen.

1992-03-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callproc.c (Fcall_process): Doc fix.

	* process.c [not defined (subprocesses)] (kill_buffer_processes):
	New dummy version of this function.
	* buffer.c (Fkill_buffer): Removed '#ifdef subprocesses'
	protection from the call to kill_buffer_processes; this is safe
	whether or not we actually have subprocesses.

1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* m/pfa50.h: New file.
	* process.c (create_process, process_send_signal): Added changes
	for m/pfa50.h.
	* sysdep.c: same.
	* unexec.c: same.

1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callproc.c (child_setup): Always put the child in its own
	process group.

1992-03-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* mem_limits.h (POINTER): Doc fix.

	* ralloc.c: Don't #include lisp.h and xterm.h; we no longer need
	to block input in critical sections.
	(r_alloc, r_alloc_free, r_re_alloc): Don't use BLOCK_INPUT and
	UNBLOCK_INPUT; these are no longer needed.
	(struct bp): Doc fix.

1992-03-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* ralloc.c (obtain): When deciding how many pages to request, take
	into account the amount of spare bytes at the end of the current
	page; let get be ROUNDUP (size - already_available), instead of
	ROUNDUP (size).
	(relinquish): Re-organized for clarity.

	* editfns.c (Fcurrent_time): Updated to return the current time's
	seconds split into two 16-bit integers (similar to the system used
	by file-attributes), and the milliseconds.

1992-03-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* process.c (Faccept_process_output): Add new optional argument
	TIMEOUT-MSECS, and return non-nil iff we actually got some input
	from the process(es).
	(wait_reading_process_input): Make return value indicate whether
	we got some input from the specified process, when read_kbd is a
	process, or from any process when read_kbd isn't particular.

	* indent.c (Fmove_to_column): Pass the correct number of arguments
	to Findent_to.

	* eval.c (Ffuncall): If a subr is asking for too many arguments,
	abort instead of printing an error message; this is an internal
	flaw in Emacs, and the subr cannot be called.

1992-03-06  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

	* doc.c (Fdocumentation, Fdocumentation_property): Take optional
	new arg to not pass results thru substitute-command-keys.

1992-03-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* unexmips.c (unexec): When setting up the data_section header,
	calculate the size of the section as "brk - data_start," not "brk
	- DATA_START".

1992-02-23  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* fileio.c: #include "systime.h".
	(Fcopy_file): Use the systime.h macros to copy the time to the new
	file.
	* ymakefile: Note that fileio.o depends on systime.h.

	* ymakefile (dispnew.o): Note that this depends on systerm.h and
	systime.h.
	(editfns.o, xterm.o, sysdep.o): Note that this depends on
	systime.h.
	(emacs.o, keyboard.o, process.o, sysdep.o): Note that these depend
	on systerm.h.

	* systerm.h: Expanded to handle getting and setting terminal
	parameters:
	(struct emacs_tty): New structure, which consolidates all of the
	old tty parameter structures.
	(EMACS_GET_TTY, EMACS_SET_TTY, EMACS_TTY_TABS_OK): New macros.
	* sysdep.c (TABS_OK): Definitions of this macro removed;
	EMACS_TTY_TABS_OK replaces it.
	(TERMINAL): Definitions removed; now we use struct emacs_tty.
	[VMS] (input_chan): Renamed to...
	(input_fd): and defined even when VMS isn't; in that case, we
	leave it initialized to zero, which is the input tty.  This allows
	us to use the EMACS_GET_TTY and EMACS_SET_TTY for both VMS and
	Unix.
	(discard_tty_input): Use struct emacs_tty and its macros instead
	of TERMINAL.  Replace some of conditional with a call to
	EMACS_GET_TTY.
	(child_setup_tty): Use struct emacs_tty and its macros instead of
	TERMINAL and conditionals.
	(old_gtty, old_ltchars, old_tchars, old_lmode): Replaced by...
	(old_tty): New variable.
	(lmode): Made conditional on BSD4_1, since it's only used by the
	BSD4_1 support code now.
	(init_sys_modes): Define tty to be a struct emacs_tty, not a
	TERMINAL.  Use macros to get and set parameters for VMS and
	Unices. Set lmode, tchars, and ltchars along with the rest of the
	tty state.
	(tabs_safe_p): Use EMACS_GET_TTY and EMACS_TTY_TABS_OK instead of
	conditionals.
	(reset_sys_modes): Use EMACS_SET_TTY to restore the settings from
	old_tty, instead of using hairy conditionals.

	* sysdep.c (get_screen_size): Neatened; now each system of
	reporting the screen size is separated from the rest.

	* systerm.h (EMACS_HAVE_TTY_PGRP, EMACS_GET_TTY_PGRP,
	EMACS_GET_TTY_PGRP): New macros to handle setting a tty's current
	process group.
	* sysdep.c (setpgrp_of_tty): Use the above, instead of
	conditionals.

	* sysdep.c: #include "systerm.h".
	#ifs that choose #include files moved from here...
	* systerm.h: to here.

	* sysdep.c [APOLLO]: We now undefine TIOCSTART not here but...
	* systerm.h: here.

	* sysdep.c [BROKEN_TIOCGETC]: We now undefine TIOCGETC not here but...
	* systerm.h: here.

	* sysdep.c [BROKEN_FIONREAD]: We now undefine FIONREAD and FASYNC
	not here but...
	* systerm.h: here.

	* process.c (process_send_signal): Steal 18.58's version of this,
	but incorporate the support for VMS signals.

	* syssignal.h (EMACS_KILLPG): New macro.
	* process.c (process_send_signal): Use it.
	* sysdep.c (sys_suspend): Use it.

	* syssignal.h (SIGCHLD): If we have SIGCLD and not SIGCHLD, define
	SIGCHLD as an alias for SIGCLD.
	* sysdep.c: Remove code for above.

	* sysdep.c (init_baud_rate): Rather than trying to maintain the
	illusion of an abstraction with the OSPEED and SETOSPEED macros,
	just use conditionalized code for each terminal kind.  This is the
	only place we ever need this functionality.
	(OSPEED, SETOSPEED): Definitions removed.

1992-02-22  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* sysdep.c: Moved definition of sigunblock macro to ...
	* syssignal.h: Here.

	* hftctl.c: #include <sys/uio.h> before #including <sys/tty.h>.
	(hfqry, hfskbd): Declare these functions as static before all uses.
	* unexaix.c (make_hdr, mark_x, copy_text_and_data, copy_sym):
	Declare as static before all uses.
	Remove extraneous semicolons from #ifdefs of COFF and XCOFF
	(unrelocate_symbols): cast the initializers of t_start and d_start
	to ulong.

	* s/template.h: Include a clause for the HAVE_TERMIO flag.

1992-02-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (read_char): Don't clear Vquit_flag when we catch an
	interrupt and return a quit_char; this change (Mar 21 1991) is too
	large a change in functionality for the cleanliness it gains.

	* pwd.h: Renamed to vms-pwd.h, so that we don't get it by accident
	when we #include <pwd.h> with the `-I.' flag given to the
	compiler.
	* editfns.c [VMS]: Changed to include vms-pwd.h instead of pwd.h.
	* fileio.c [VMS]: Same.
	* filelock.c [VMS]: Same.
	* sysdep.c [VMS]: Same.

	* xrdb.c: Changed to #include "vms-pwd.h" if VMS is defined,
	instead of including <pwd.h> unconditionally.

	* window.c (Fset_window_display_table): Rearranged to make etags
	happy.

	* xterm.c (XTread_socket): Clear the meta flag from the keypress
	event before handing it to XLookupString.

1992-02-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* sysdep.c: No need to test #ifdef TIOCGETP before #undefing it.

1992-02-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* systime.h: New file.
	* dispnew.c: #include "systime.h" to get <time.h> or <sys/time.h>,
	whichever is appropriate, instead of using a conditional.
	(Fsleep_for, Fsit_for, Fsleep_for_millisecs): Use the systime.h
	macros instead of HAVE_TIMEVAL conditionals.
	* editfns.c: #include "systime.h" to get <time.h> or <sys/time.h>,
	whichever is appropriate, instead of using a conditional.
	* fileio.c: Same.
	* process.c: Same.
	* xterm.c: Same.
	(wait_reading_process_input): Use the systime.h macros.
	* sysdep.c: #include "systime.h" to get <time.h> or <sys/time.h>,
	whichever is appropriate, instead of using a conditional.

	* m/template.h: Add description of NO_SOCK_SIGIO.

	* sysdep.c (reset_sys_modes): Doc fix.

	* keyboard.c (sigfree, sigholdx, sigblockx, sigunblockx,
	sigpausex): Definitions moved to syssignal.h.

	* dispnew.c: Doc fix.

	* systerm.h: New file, to consolidate the system-dependent
	terminal-handling trash.
	* emacs.c: #include systerm.h.
	(main): Use systerm.h macros instead of conditionals.
	* dispnew.c: #include systerm.h.
	(update_screen): Use EMACS_OUTQSIZE instead of the direct ioctl.
	* keyboard.c: #include systerm.h to get the proper FIONREAD header
	files, instead of using conditional.

	* syssignal.h: Added copyright notice.

	* emacssignal.h: Renamed to syssignal.h, to be like sysdep.c.
	* data.c, keyboard.c, process.c, sysdep.c, ymakefile: Changed
	#include directives.

1992-02-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* m/intel386.h: Don't bother casting the argument to the signal
	function; the SIGTYPE code in config.emacs ought to take care of
	this.

	* buffer.c (record_buffer): Doc fix.

1992-02-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* s/iris3-6.h: #define HAVE_GETWD.

1992-02-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* window.c (Fwindow_at): Accept position as two arguments, not a
	cons of numbers.

	* window.c (scroll_command): Undo the Jan 31 change; do set the
	current buffer to the selected window's buffer.  A simple
	set-buffer will make these two different.

1992-02-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* callproc.c (Fcall_process): Clear synch_process_death and
	synch_process_retcode to zero before forking the process.

	* process.c (synch_process_death, synch_process_retcode): Don't
	declare them extern here.
	* process.h (synch_process_death, synch_process_retcode): Declare
	them extern here, along with synch_process_alive.

	* s/hpux.h: Define CLASH_DETECTION.

	* window.c (init_window_once): Don't pass any arguments to
	make_window.

	* keyboard.c (command_loop_1): Move the label directly_done out of
	the else block to just after the else block.  This shouldn't
	change the semantics of the code, but appears to avoid a compiler
	bug on SCO Unix V.3.2v2.

	* fileio.c (Fset_umask, Fumask): New functions.
	(syms_of_fileio): defsubr them.

	* undo.c (Fprimitive_undo): When undoing a deletion with the point
	before the deleted text, use Finsert_before_markers so that the
	mark will end up on the other side of the text, if it's in the
	area at all.

	* xdisp.c (redisplay): Properly compute TAB_OFFSET for compute_motion.

	* keyboard.c (command_loop_1): Don't check whether cursor is at
	edge of screen here.
	* dispnew.c (direct_output_forward_char): Check here, and return
	zero if it can't be done.  And compare the cursor position to the
	window boundaries, not the screen boundaries.

1992-02-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* screen.c (Fscreen_parameters): If the screen has a minibuffer
	window on another screen, return the window, instead of nil.
	(store_screen_param): If the value of the minibuffer parameter is
	a window, try to make it the surrogate minibuffer window.
	(Qminibuffer): New variable, to support above change.
	(syms_of_screen): initialize and staticpro it.

	* m/tad68k.h: New file.

	* fileio.c (Ffile_accessible_directory_p): New function.
	(syms_of_fileio): defsubr it.
	* callproc.c: #include <errno.h>.
	(child_setup):  Accept yet another argument, current_dir.
	Don't try to report an error here if current_dir is inaccessible;
	this function is called in a vforking process.  Just have the
	process exit with an error code.
	(Fcall_process): Make sure that the current directory is okay
	here, before we fork.  Pass the current_dir argument.
	* process.c (create_process): Same here.

	* callproc.c (Fcall_process): Don't assign into args[1] when nargs
	< 2.  Instead, use a new variable called infile.  Re-arranged
	logic which processes the BUFFER argument.

1992-02-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* fileio.c (Fexpand_file_name): Doc fix.

	* scroll.c (line_ins_del): Since we're calculating the array from
	end to beginning, make the indices go that way, and thus clearly
	get the right boundary.  This used to ignore the [0] element, and
	write in the [screen_height] element, which doesn't exist.

1992-02-03  Richard Stallman  (rms@mole.ai.mit.edu)

	* xdisp.c (redisplay, try_window_id): Special case for change
	at beginning of line, if using selective display.

1992-01-31  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* m/delta88k.h: Added USUAL-OPSYS information, for the
	config.emacs script to use.

	* window.c (scroll_command): Don't bother setting the current
	buffer to the selected window's buffer; this should always already
	be the case.  Add check just in case.

	* indent.c (compute_motion): Don't pack vpos and hpos into one int;
	use separate variables hpos/vpos and prev_hpos/prev_vpos.
	(vmotion): Use largest int as tovpos arg to compute_motion.

1992-01-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* window.c: #include "keyboard.h" to get the Qmode_line and
	Qvertical_split declarations.
	* ymakefile (window.o): Note that this depends on keyboard.h.

	* callproc.c (getenv_internal): Cast the pointer to the variable's
	value to a char *; elisp strings are unsigned char *'s.  And
	valuelen is an int *, not an int **.

	* scroll.c (do_scrolling): Document meaning of enable flag in
	temp_screen.

1992-01-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * m-orion105.h (C_DEBUG_SWITCH, LIBS_DEBUG): Defs deleted.

1992-01-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* m-iris4d.h (C_SWITCH_MACHINE): New definition.

1992-01-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* term.c: #include "keyboard.h", for Vfunction_key_map.
	* keyboard.h: Declare Vfunction_key_map.

	* keyboard.h: New file, for external declarations used in
	processing keyboard input and events.
	* lisp.h (Qmode_line, Qvertical_split, num_input_chars,
	poll_suppress_count): Extern declarations moved to keyboard.h.
	* keyboard.c: #include "keyboard.h".
	(Qvscrollbar_par, Qvslider_part, Qvthumbup_part,
	Qvthumbdown_part, Qhscrollbar_part, Qhslider_part,
	Qhthumbleft_part, Qhthumbright_part): Moved declarations here from
	xfns.c, so they're with the other event heading symbols.
	* eval.c: #include "keyboard.h".
	* ymakefile (callint.o, keyboard.o, keymap.o, xfns.o, eval.o):
	Note that these depend on keyboard.h.

	* xfns.c: The above symbols aren't here any more.  #include
	"keyboard.h" to get them.
	(syms_of_xfns): Don't initialize or staticpro them.
	* keyboard.h: Added extern declarations for the above.
	* callint.c: #include "keyboard.h".

	* xfns.c (Vmouse_screen_part): Variable removed, no longer used.
	(syms_of_xfns): Changed accordingly.

	* xterm.c (Qmouse_moved): Variable removed, no longer used.
	(Qmouse_click, Qscrollbar_click): Removed.  These are now event
	types, in keyboard.c and keyboard.h; they're no longer used in
	this way.
	(Vmouse_window, Vmouse_screen_part): Extern declarations removed.
	(XTread_socket): Don't assign to Vmouse_window or
	Vmouse_screen_part.
	(syms_of_xterm): Changed accordingly.

	* keyboard.h (EVENT_HAS_PARAMETERS, EVENT_HEAD, EVENT_WINDOW,
	EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON, EVENT_WINDOW_POSN,
	EVENT_TIMESTAMP, EVENT_HEAD_UNMODIFIED, EVENT_HEAD_KIND): New
	macros to recognize and access events that have parameters, like
	mouse events.
	* keyboard.c (read_char, echo_char, Fmouse_click_p,
	read_key_sequence): Use them.
	* keymap.c: #include "keyboard.h".
	(access_keymap, store_in_keymap, Fsingle_key_description): Use the
	macros from keyboard.h.

	* keyboard.c (Qevent_kind): New symbol, naming the property of an event
	header where we put the event's type.
	(Qfunction_key, Qmouse_click, Qscrollbar_click): New symbols, used
	to tag different kinds of events.
	(Qevent_unmodified): New symbol, naming the property
	of an event header where we put an unmodified version of the event
	header.
	(modify_event_symbol): Take a new argument, SYMBOL_KIND, whose
	value should be put on the Qevent_kind property of each symbol we
	make.  Set the Qevent_unmodified property of each symbol we make.
	(make_lispy_event): Pass the appropriate SYMBOL_KIND argument to
	modify_event_symbol.
	(struct event_head, head_table): New tables, to simplify the
	initialization of some of the event heads.
	(syms_of_keyboard): Initialize and staticpro the symbols given in
	head_table, and put the Qevent_kind and Qevent_unmodified
	properties on them.  Initialize all of the new symbols listed
	above.

	* keyboard.c (lispy_function_keys, lispy_mouse_names): Renamed
	these from function_key_names and mouse_names, and moved them
	outside of make_lispy_event, since static doesn't work on all
	systems, and these can't be automatic.

1992-01-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* fileio.c (Fwrite_region): Remove Alliant conditional.
	* crt0.c: Conditionals for ALLIANT_2800.
	* m/alliant-2800.h: New file.
	* unexfx2800.c: New file.

	* m-mips4.h (C_DEBUG_SWITCH): Alternate defn for GCC.

	(LIB_STANDARD): Add -lPW.
	(LIBS_SYSTEM): Defined.
	* m/intel386.h (signal): Optionally don't define it.

1992-01-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* s/template.h: Document the SIGTYPE macro.
	* s/bsd4-3.h: Define the SIGTYPE macro.

	* data.c (Fsymbol_value): Extract all the innards of this function
	into find_symbol_value, except the code which signals an error.
	(find_symbol_value): New function.
	* lisp.h (find_symbol_value): Declare it.
	* keymap.c (current_minor_maps): Use it, instead of a call to
	Fboundp and Fsymbol_value per every minor map, for every key
	sequence read.

	* xterm.c (x_make_screen_visible): Don't raise the window.  This
	causes the window to pop to the front every time a message
	appears, which isn't desirable.

	* screen.c (Fselect_screen, Fdelete_screen, Fset_mouse_position,
	Fmake_screen_visible, Fmake_screen_invisible, Ficonify_screen,
	Fdeiconify_screen, Fscreen_parameters, Fmodify_screen_parameters,
	Fset_screen_height, Fset_screen_width, Fset_screen_size,
	Fset_screen_position): Use SCREEN_IS_X macro instead of testing
	for output_x_window.
	* xfns.c (adjust_scrollbars, Fx_store_cut_buffer): Same.

1992-01-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* term.c (term_get_fkeys): New function.

	* lisp.h (Ffollchar, Fprevchar): Renamed extern declarations as above.

	* editfns.c (Ffollowing_char): Return 0 at the end of the buffer,
	as advertised.  Doc fix.
	(Fprevious_char): Doc fix.

	* config.h-dist: Rearranged to define user parameters before
	including the machine and opsystem files, so the files can have
	conditionals on the parameters.

1992-01-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* keyboard.c (read_key_sequence): When expanding a function key
	recognized with Vfunction_key_map, don't scan the expansion for
	further function key sequences.

	* keyboard.c (Vfunction_key_map): Real declaration moved to
	keymap.c; this declaration made extern.
	(syms_of_keyboard): DEFVAR and initialization of Vfunction_key_map
	moved to keymap.c, since it should be initialized to a keymap, but
	we don't want to rely on Qkeymap being initialized now.
	* keymap.c (Vfunction_key_map): Variable moved here.
	(syms_of_keymap): DEFVAR and init here.

	* keymap.c (Fglobal_key_binding): Doc fix.

1992-01-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* m-delta88.h: New file.

	* window.c (window_scroll): New arg `noerror'.

1992-01-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* process.c (sigchld_handler):
	Set synch_process_death and synch_process_retcode.

1992-01-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* config.h-dist (SIGTYPE): New macro to help give signal handlers
	the correct type.
	* s/usg5-3.h (SIGTYPE): Define this to be void.
	* dispnew.c (window_change_signal): Declare this to return
	SIGTYPE.
	* emacs.c (fatal_error_signal): Same.
	* data.c (arith_error): Same.
	* process.c (create_process_1, send_process_trap,
	create_process_sigchld, sigchld_handler): Same.
	(create_process): Declare sigchld according to SIGTYPE.  This
	means we don't have to cast the return value of signal.
	* keyboard.c (input_poll_signal, interrupt_signal): Declare these
	to return SIGTYPE.
	(kbd_buffer_store_event): Include a forward declaration for
	interrupt_signal here.
	* sysdep.c (struct save_signal): Say the handler returns SIGTYPE
	instead of int.
	(save_signal_handlers): So we don't have to cast the return value
	from signal here.
	(sys_suspend): Declare oldsig according to SIGTYPE.
	(select): Declare old_trap using SIGTYPE.
	(select_alarm, wait_for_termination_signal): Declare these to
	return SIGTYPE.

	* emacs.c: #include <termios.h>, if we have it.
	(fatal_error_signal): If we have termios, use tcgetpgrp to get the
	terminal's process group.
	* process.c: If we have termios, #include <termios.h> instead of
	<termio.h>.
	(process_send_signal): If we have termios, use tcgetpgrp to get
	the terminal's process group.  Have gid default to the child's
	pid, to simplify the logic below.
	* sysdep.c (flush_pending_output): If we are using termios, make
	this function a no-op; since we're not in the tty's pgroup, we
	would get a SIGTTIN.

1992-01-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

	* config.h-dist: Removed MAINTAIN_ENVIRONMENT clause.
	* callproc.c: Removed support for MAINTAIN_ENVIRONMENT.
	(init_callproc): Use getenv instead of egetenv to initialize
	Vshell_file_name.
	* emacs.c (decode_env_path): Use getenv instead of egetenv
	* lisp.h: Removed support for MAINTAIN_ENVIRONMENT.
	* process.c: Same.
	* ymakefile: Same.
	* dispnew.c (init_display): Call getenv instead of egetenv.

	* editfns.c (Fgetenv): Function moved...
	* callproc.c (Fgetenv): To here, and made to scan
	Vprocess_environment instead of using the usual C getenv function.
	(getenv_internal): New function.
	(egetenv): New function.
	* lisp.h: Added extern declaration for egetenv.
	* editfns.c (syms_of_editfns): Adjusted.
	* callproc.c (syms_of_callproc): Adjusted.

	* window.h (minibuf_prompt_width): Declare this extern here, after
	minibuf_prompt.
	minibuf.c: Don't extern declare it here.
	indent.c: As above.

	* dispnew.c (buffer_posn_from_coords): If there is a prompt in the
	minibuffer, account for its width when computing the buffer
	position.

	* Makefile (doall): Explicitly export CC to the xmakefile.

	* ymakefile: Use /* */ around comments; # confuses cpp.

	* ymakefile: Note that ralloc.o depends on mem_limits.h, xterm.h,
	and config.h.
	Note that vm-limit.o depends on mem_limits.h.

	* lread.c (read_escape): Return \a as '\007', not '\a'; the latter
	isn't portable, and this routine would have to be revised anyway
	to deal with anything other than ASCII.

	* keymap.c (current_minor_maps): Rewritten not to use
	function-local static variables, to accomodate DGUX.

	* xterm.h (UNBLOCK_INPUT): Replace "abort ()" with "(abort (),
	0)", to avoid type conflicts on odd systems like Ultrix.

	* xrdb.c: Include <sys/types.h>, and declare getuid to return uid_t.

	<stdio.h>, and <stddef.h>.  All callers changed; all
	#undefinitions of NULL removed.

	arguments to read_key_sequence.
	(command_loop_1): Don't pass too many arguments to read_key_sequence.

	* keyboard.c (add_command_key): New function; there are several

	instead of writing out its code again.
	(init_keyboard): Allocate this_command_keys according to

	used.

1991-12-08  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* editfns.c (Fcurrent_time): New function, to return the current
	time as a number, like the Unix time(3) function.  This might be
	fun to port.
	(syms_of_editfns): defsubr it.

1991-12-05  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* callproc.c (Vdata_directory): New lisp variable, for the
	directory containing architecture-independent data files.
	(init_callproc): Initialize Vdata_directory from PATH_DATA, and
	make sure it exists.  Renamed execdir to tempdir, because we use

	for Vdata_directory.
	* paths.h-dist (PATH_DATA): New path macro, to initialize

	* callint.c (Fcall_interactively): For the 'k' interactive code,
	cast the type of the symbol name before passing it to error.

1991-12-02  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (make_lispy_movement): Move call to

	(kbd_buffer_get_event): To here, for symmetry with non-movement
	events.

	* keyboard.c (kbd_buffer_get_event): Set Vlast_event_screen for
	mouse movements, too.

	Emacs.  Handle batch-mode errors with the same code.
	* lisp.h (Qexternal_debugging_ouput): New extern declaration, for
	use in cmd_error.

	* screen.c (Fscreen_pixel_size, Fset_screen_position): Doc fix.

	screen, so make its definition the same as in the MULTI_SCREEN
	case.

	* screen.h (SCREEN_LIVE_P): New predicate.
	(CHECK_LIVE_SCREEN): New type-checking macro.

	* screen.c (Fdelete_screen): Do nothing if SCREEN is already
	deleted.

	* screen.c (Qscreenp): Staticpro this symbol.

	* xfns.c (Fx_create_screen): Doc fix.

	* xfns.c (Fx_create_screen): Give the screen a minibuffer if the

	of next_screen_window.

	* xdisp.c (redisplay): Don't clear out minibuffer windows in the
	midst of the screen loop here.  That's confusing.
	(redisplay_window): Since this needs special code to detect
	minibuffers anyway, put it here.  And clear all the lines of a
	multi-line minibuffer, not just the first one.

1991-11-07  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* screen.c (Fdelete_screen): When searching Vscreen_list for a new
	value for last_nonminibuf_screen, remember that the screens live
	in the cars of the list, not the cdrs.

	* xterm.c (x_make_screen_visible): Rearranged for clarity.

	* xdisp.c (echo_area_display): Rearranged for clarity.

1991-11-06  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	screen after the current buffer not depend on
	Vglobal_minibuffer_screen.
	* xterm.c (Vglobal_minibuffer_screen): Don't declare this extern
	here; it's never used.

1991-11-05  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* screen.c (Fdelete_screen): Document the fact that surrogate
	minibuffer screens may not be deleted.

	* screen.h (SCREEN_MINIBUF_ONLY_P): New predicate, true iff the
	screen's only window is a minibuffer, aka a "minibuffer screen" or
	a "minibuffer-only" screen.
	* dispnew.c (change_screen_size): Use it.
	* screen.c (Fselect_screen, next_screen, prev_screen,
	Fdelete_screen): Use it.

	* window.c (Fnext_window, Fprevious_window): Changed to fit.

	* screen.c (make_screen_without_minibuffer): Error string improvement.

	* screen.c (syms_of_screen): Doc grammar fix for Vemacs_iconified.

	* screen.c (next_screen): Added some sanity checks, rewrote comments.

	* screen.h (Vglobal_minibuffer_screen): Don't declare this.  It
	shouldn't be used for anything but screen creation.
	* window.c (Fminibuffer_window): Vglobal_minibuffer_screen is not
	necessarily the screen containing the current minibuffer window.
	Also, call choose_minibuf_window; it does much of the work here.
	(Fnext_window): Used to insist on looping through all screens if
	Vglobal_minibuffer_screen was non-nil.  Now includes screen's
	minibuffer window according to MINIBUF, no matter what screen it's
	on, and ignores Vglobal_minibuffer_screen.  Loop termination logic
	cleaned up.  Clarified doc string.
	(Fprev_window): Same problems as Fnext_window, above.
	* screen.c (Vglobal_minibuffer_screen): Documentation rewritten to
	emphasize that it is only a parameter of the creation of
	minibufferless screens, and not an indication of where the
	minibuffer is.
	(prev_screen): Used to assume that Vglobal_minibuffer_screen was
	the only minibuffer-only screen, and would enter an infinite loop
	if Vglobal_minibuffer_screen was the only screen in the list.
	Rewritten to fix these problems.
	* minibuf.c (Vglobal_minibuffer_screen): Don't declare it extern
	here; it's not used.

	* editfns.c (Fmessage): Don't call Fmake_screen_visible here.
	* xdisp.c (message, message1): Call it here, so that Emacs C
	functions like Fy_or_n_p make the screen visible too.

1991-11-04  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (readable_events): If EVENT_QUEUES_EMPTY, we can
	short-circuit and say no.  Otherwise, if do_mouse_tracking, we can
	short-circuit and say yes.  These things let us scan the event
	queue less often.

	* termhooks.h (mouse_tracking_enable_hook): Replaced by...
	(mouse_moved, mouse_position_hook): It turns out that it is
	possible and no less efficient simply to tell Emacs if the mouse
	has moved since last noticed, and let it ask for the current mouse
	position; X's pointer motion hints are a cool thing.
	* term.c (mouse_tracking_enable_hook): Replaced by...
	(mouse_position_hook): New, simpler interface.
	* keyboard.c (struct movement, movement_buf, movement_ptr):
	Replaced by...
	(mouse_moved): This flag, to be used in conjuction with
	mouse_position_hook.
	(EVENT_QUEUES_EMPTY): Adjusted to use mouse_moved instead of
	movement_buf and movement_ptr.
	(tracking_off, Ftrack_mouse): Don't call mouse_tracking_enable
	hook.
	(note_mouse_position): Moved to xterm.c.
	(get_mouse_position): Replaced by mouse_position_hook.
	(make_lispy_event): Movement event generation code moved out to a
	separate function...
	(make_lispy_movement): Create a mouse movement event for the
	current mouse position.  Use mouse_position_hook instead of
	get_mouse_position.  Added static declaration for this above...
	(kbd_buffer_get_event): Use mouse_moved instead of movement_buf
	and movement_ptr.  Call make_lispy_movement instead of
	make_lispy_event.
	(init_keyboard): Initialize do_mouse_tracking.  Don't init
	movement_ptr and movement_buf.
	* xterm.h (STANDARD_EVENT_SET): Add PointerMotionMask and
	PointerMotionHintMask to the set.
	* xterm.c (pixel_to_glyph_translation): Renamed to
	pixel_to_glyph_coords, made static, simplified to take advantage
	of constant-size characters, and extended to return the bounding
	rectangle of the glyph returned.
	(construct_mouse_click): The 'button' field of a button event is
	the button number, not a mask; convert it to a mask before
	frobbing x_mouse_grabbed.  Call pixel_to_glyph_coords properly.
	(last_mouse_screen, last_mouse_glyph): New variables, to keep
	track of when the pointer has moved to a different glyph.
	(note_mouse_position): Moved here from keyboard.c and made static.
	Check if the new mouse position is over a new glyph.  If it is,
	set mouse_moved flag; otherwise, call XQueryPointer to get the
	next motion event.
	(XTmouse_tracking_enable): No longer needed, since pointer motion
	hints let us implement the simpler mouse position hook.
	(XTmouse_position): New hook.  Call XQueryPointer to get the
	current mouse position and request notification about the next
	mouse movement.  Clear the mouse_moved flag.
	(pixel_to_glyph_coords, construct_mouse_click,
	note_mouse_position, XTmouse_position): Put these all on the same
	page.
	(XTread_socket): case MotionNotify, call note_mouse_position with
	the right args; don't call pixel_to_glyph_translation.
	(x_term_init): Set mouse_position_hook instead of
	mouse_tracking_enable_hook.

1991-10-31  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xdisp.c (redisplay_window): When trying to avoid starting
	display at the end of the buffer: check that startp < ZV, not
	startp <= ZV.

1991-10-29  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xterm.c (x_do_pending_expose, XTmouse_tracking_enable): Use
	SCREEN_IS_X instead of testing output_method directly.

1991-10-26  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xdisp.c (redisplay): In the single-screen optimization, always
	update the minibuffer's screen as well as the selected screen, no
	matter what the echo_area_glyphs are.  This makes sure that
	messages get cleared after a keystroke.

1991-10-25  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* callint.c (Finteractive): Doc fix.

	* xterm.c (XTmouse_tracking_enable): Block input while changing
	the screens' input selection masks.

	* window.c (change_window_height): If the window being resized is
	the only window of the screen, no size change is possible; make
	the delta be zero.  Exit without "changing" the sizes of any
	windows if the delta is zero.

	* alloc.c: Don't bother to include xterm.h.
	(Fgarbage_collect): Don't bother to BLOCK_INPUT here,
	since we don't cons in the input handler.

1991-10-21  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* window.c (init_window_once): Set last_nonminibuf_screen to the
	initial terminal screen, so that poor Fdisplay_buffer doesn't try
	to create a new screen on a terminal.

1991-10-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* m-intel386.h (signal): Optionally don't define it.
	* s-isc2-2.h (DONT_DEFINE_SIGNAL): Define this.

1991-10-18  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* scroll.c (line_ins_del): Don't calculate costs off the end of mf
	and ov; use < in loop condition, not <=.

	* scroll.c (scroll_cost): Logic rearranged.

	* dispnew.c (change_screen_size): Change "SCREEN_IS_TERMCAP
	(screen) == output_termap" to "SCREEN_IS_TERMCAP (screen)"
	(window_change_signal): Use SCREEN_IS_TERMCAP predicate instead of
	testing output_method_directly.

	* xterm.h (STANDARD_EVENT_SET): Include ButtonReleaseMask in
	STANDARD_EVENT_SET.
	* xterm.c (XTmouse_tracking_enable): Don't bother or'ing
	ButtonReleaseMask with the STANDARD_EVENT_SET.

	* dispnew.c (buffer_posn_from_coords): If the coordinates are off
	past the end of a line, return them as being *before* the newline,
	not after.

	* keyboard.c (kbd_buffer_get_event): Set input_pending after
	reading the event, no matter what sort of event it is - i.e., move
	the assignment to input_pending outside of the event lispifying
	conditional.

	* keyboard.c (note_mouse_position): Don't record a "new" mouse
	position unless it really differs from the last one returned.

	* keyboard.c (kbd_buffer_read_char): Renamed to
	kbd_buffer_get_event, for consistency with kbd_buffer_store_event.

	* window.c (Fwindow_at): modified to take the coordinates as a
	pair, not a two-element list, for ease of use and compatibility
	with events.  Make SCREEN argument second and optional.
	(Fcoordinates_in_window_p): Modified to take and return the
	coordinates as above, and to distinguish the right border as well
	as the mode line.
	(window_from_coordinates): Modified to distinguish the right
	border as well as the mode line.
	* lisp.h (Qmode_line, Qvertical_split): Declare this extern, from
	keyboard.c.
	* keyboard.c (make_lispy_event): Distinguish a window's right
	border from its text area.

	* screen.c (Fcoordinates_in_window_p, window_from_coordinates,
	Flocate_window_from_coordinates): Functions moved to window.c.
	(syms_of_screen): Adjusted.
	* window.c (Fcoordinates_in_window_p, window_from_coordinates,
	Flocate_window_from_coordinates): Here they are.
	(syms_of_window): Adjusted.
	* lisp.h: Adjusted to say so.

1991-10-14  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xterm.c (XTclear_end_of_line): This used to try to get the
	cursor out of the way by comparing the line being cleared with
	s->cursor_y, which is meaningless; it should have compared it with
	s->phys_cursor_y.  Changed to just mark the cursor as cleared if
	it's in the area we're clearing.

1991-10-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* m-intel386.h: Fix typo in #endif.

1991-10-12  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* callint.c (Fcall_interactively): Added new interactive spec 'K',
	for mouse clicks.  Added explanation to doc string.  Removed 'e'
	spec, which didn't work with the new input model anyway.
	* keyboard.c (Fmouse_click_p): New function.
	(syms_of_keyboard): defsubr it.

	* keyboard.c (EVENT_QUEUES_EMPTY): Clarified comment.
	(tracking_off): Change "if (!readable_events)" to
	"if (!readable_events ())".
	(Ftrack_mouse): Doc fix.
	(kbd_buffer_read_char): Fix brainos in tossing of unwanted events.
	Don't use EVENT_QUEUES_EMPTY to set input_pending; call
	readable_events.

1991-10-11  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (Qmode_line): New quoted symbol.
	(syms_of_keyboard): Initialize and staticpro it.
	(make_lispy_event): Use it to indicate when a mouse position is in
	a window's mode line.

	* xterm.c (XTread_socket): Consider the window to be resized if
	either the character or pixel dimensions have changed; this will
	catch font size changes.

1991-10-08  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* process.c (wait_reading_process_input): Removed all the
	exceptional condition stuff.  Emacs lacks any way to respond to
	such a state, and selecting for it without responding to it can make
	Emacs loop indefinitely.

	* xterm.c (XTread_socket, construct_mouse_click): Make sure that
	all enqueued events have their timestamp field set.
	* termhooks.h (struct input_event): Doc fix.

	(last_event_timestamp): Use this instead.
	(Fx_own_selection, Fx_own_clipboard, Fx_get_selection,
	Fx_get_clipboard): Use last_event_timestamp instead of
	mouse_timestamp.

	* xdisp.c (redisplay): Don't pass extra arguments to

	to put the character we just read into the minibuffer, if
	appropriate.

	* keyboard.c (read_key_sequence): Removed unused argument
	no_redisplay.

1991-10-01  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xterm.c (x_display_bar_cursor): Declare this to be static void.

	* xterm.c (XTupdate_begin): Don't turn off the cursor.  This makes
	ugly flickering.  Instead, make it okay for XTins_del_lines to do
	so:
	* screen.h (struct screen): New field phys_cursor_glyph, keeping
	track of the glyph under the currently displayed cursor.  Since
	current_glyphs is sometimes inaccurate when we want to undraw the
	cursor (as when XTins_del_lines is called from do_scrolling), we
	can't always get the GLYPH from there.
	* xterm.c (x_draw_single_glyph): Take the glyph to draw as an
	argument, instead of taking it from the screen matrix.
	(x_display_box_cursor): Set and use s->phys_cursor_glyph.

	event, use `m', not `event', dummy.

	* screen.c (Fscreen_parameters): Return the proper value for the
	'minibuffer parameter for minibuffer-only screens.

	* xdisp.c (redisplay_window): When the start position is forced,
	constrain it to be within the visible region anyway.

	* xterm.c (XTwrite_glyphs): Instead of turning off the cursor
	before we write, just notice if we wrote over it.

	* xfns.c (x_decode_color): If a screen has two planes, then it is
	considered a color screen, and we should look up the color value.

	* ymakefile: Include xselect.o and xrdb.o in XOBJ even when
	HAVE_X_MENU is not defined.

	* fns.c (Fdelete): This used to be named Fdelq; Roland forgot to

	Fx_get_resource.

	* xfns.c (x_get_arg, x_default_parameter): Take an extra argument
	TYPE, instead of encoding the type in the first letter of the
	property name.

1991-08-15  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

	* buffer.c (Fkill_all_local_variables): Don't pass
	Fmake_local_variable too many args.  Use Fset instead.

1991-08-14  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xfns.c (emacs_class): Variable removed.

	screen.el to here.
	(syms_of_screen): DEFVAR_LISP and initialize it here.

	* screen.c (next_screen): Re-work logic to skip minibuffer-only

	* ymakefile: Added puresize.h to dependencies for alloc.c and
	data.c's .o files.

	* emacs.c (main): Doc fix for kludge to scan for -d.

1991-07-17  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* termhooks.h (struct input_event): #if 0'd out the definition for
	the screen_selected event type, and added the stipulation that the
	{non_,}ascii_keystroke events specify the screen they happen in.
	* xterm.c (x_new_focus_screen): Don't enqueue a screen_selected
	event.
	(XTread_socket): Calls to x_new_focus_screen in the EnterNotify,
	FocusIn, LeaveNotify, and FocusOut event code don't worry about
	enqueued events any more.
	* keyboard.c (new_selected_screen): Removed - see below.
	(Vlast_event_screen): New variable, visible to lisp code.
	(echo_length, echo_truncate): New functions.
	(readable_events): Removed screen_selected events from the set of
	things to skip.
	(kbd_buffer_store_event): Don't bother collapsing consecutive
	screen_selected events.
	(kbd_buffer_read_char): Don't process screen_selected events.
	(make_lispy_event): Re-arrange scrollbar events to put the window
	whose scrollbar was diddled right after the identifying symbol,
	for consistency.
	(read_key_sequence): Let the selected screen and the location of
	the event affect the keymap used to find its binding.
	(Fread_key_sequence): Update docstring.
	(syms_of_keyboard): Added DEFVAR_LISP for Vlast_event_screen.

1991-07-15  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* screen.c (next_screen): If !mini_screen, only exclude the global
	minibuffer screen when the minibuffer is its only window.
	(Fnext_screen): Make the docstring clearer about what MINISCREEN
	means.

	* window.c (Fother_window): Indicate that it takes both a required
	and optional argument, instead of just one required.

1991-07-15  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* buffer.c (Fkill_buffer): Rehacked kill-buffer-hooks to use
	standard name kill-buffer-hook, and to use set_buffer_internal
	instead of Fset_buffer.  Use static variable containing symbol
	instead of intern.
	(syms_of_buffer, init_buffer_once): Qkill_buffer_hook =
	'kill-buffer-hook.

1991-07-15  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keymap.c (Fsingle_key_description): When describing a listy
	object, take the car to find the symbol that heads it, not the cdr.

	* dispnew.c (buffer_posn_from_coords): Pass col and line to
	compute_motion in the correct order.

	* keyboard.c (make_lispy_event): When calculating rows and columns
	for mouse clicks and movement events, don't forget to subtract the
	position of the window's top left corner before passing them to
	buffer_posn_from_coords.

	* screen.c (coordinates_in_window): Removed useless test for *y ==
	screen_height, and screen_height variable; this would be out of
	range of all the windows anyway.

	* xdisp.c (message1): Removed code to ignore messages before X has
	started up; this issue has hopefully been addressed by the
	condition-case in startup.el.

	* editfns.c (init_editfns): Make user_name char * instead of
	unsigned char *, since that's what most of the usages seem to
	want.  And when expanding ampersands in AMPERSAND_FULL_NAME mode,
	don't try to use user_name as a string; use Vuser_name.

	* minibuf.c (assoc_for_completion): New function.
	(do_completion): Use that to check for exact match.

	* minibuf.c (Ftry_completion):  Fix handling of matches aside from
	case.  If ignoring case, and all else equal, try to preserve the
	case of the characters in the input.

	* process.c (status_notify): GCPRO tail.

	* sysdep.c (creat_copy_attrs, rename_sans_version):  Always set
	protection to O:REWD when creating file.  Added new function
	rename_sans_version, which strips the version number from the target
	filename, renames the temporary file to this filename,  and then
	sets the file protection of this new file to be the same as the file
	being edited.

	* sysdep.c [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
	(F_SETFL) [VMS]: Undefine this, to control conditionals.
	(getpwnam): Make `full' unsigned.
	(creat_copy_attrs): Add some casts.
	(sys_access): Change prvmask and CHECKPRIV to use bitfields.
	Add some casts, and make dummy an unsigned short int.
	Don't use & on constants.
	(vmserrstr): Add a cast.
	(sys_creat): Define va_count before this function.

1991-07-14  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* sysdep.c (sys_sleep, input_wait_timeout): Don't use & on constant.
	[VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
	(bzero, bcopy) [VMS]: Don't take address of `length'.

	* sysdep.c (sys_suspend): Cast value of `signal' to insulate from
	changed value type in sysV.3.

	* sysdep.c (child_setup_tty): Turn off erase & kill chars for BSD.

	* sysdep.c (discard_tty_input): Use TIOCFLUSH on Apollo.
	(init_sys_modes): Avoid TIOCSTART on Apollo.

	* sysdep.c: If HAVE_TERMIOS is not defined, define tcgetattr in
	terms of the TIOCGETP ioctl.
	(init_sys_modes): Handle VSUSP, V_DSUSP if HAVE_TCATTR.
	(discard_tty_input, init_baud_rate, child_setup_tty,
	init_sys_modes, tabs_safe_p, reset_sys_modes):
	Use tcgetattr, and if HAVE_TCATTR, use tcsetattr.

1991-07-13  Jim Blandy  (jimb@churchy.gnu.ai.mit.edu)

	* s-hpux8.h: New file.
	* fileio.c [HPUX8]: Don't include errnet.h.

	* unexhp9k800.c (unexec): Local variable i to avoid compiler bug?

	* sysdep.c (insque) [WRONG_NAME_INSQUE]: New function.
	* s-386ix.h (WRONG_NAME_INSQUE): Define it.

	* xdisp.c (message_buf_print): New variable.
	(message): Clear it here.
	* dispextern.h: Declare it here.
	* print.c (printchar, strout): Set it and test it here.

	* keyboard.c (command_loop_1): Don't clear last_command when start
	macro.

	* keyboard.c (read_command_char): Exit at eof if noninteractive.

	* indent.c (invalidate_current_column): New function.
	* editfns.c (Fwiden, Fnarrow_to_region): Call it.

	* process.c (create_process): Use O_NOCTTY whenever defined,
	unless USG.

	* process.c (Fprocess_send_eof): If using a pipe, close it.
	(close_process_descs): Check IN and OUT for nonzeroness.

	* process.c (process_send_signal): Use interrupt chars
	to send certain signals to the process group.
	(TIOCGETC): Undefine this if it is not really usable.

	* sysdep.c (discard_tty_input): Do nothing if read_socket_hook.

	* xfns.c (x_set_mouse_color): Change the default pointer shapes to
	be closer to xterm and emacs 18.

	* xterm.c (x_focus_on_screen, x_unfocus_screen): These no longer
	call XSetInputFocus, because I think that the X-windows ICCCM
	says that only the window manager can do this sort of thing.

	* keyboard.c (read_char): When there is an unread command
	character, goto reread_first when this_command_key_count is zero,
	not when it is >= 0.
	(command_loop_1): Reset this_command_key_count only if there is no
	prefix argument.  This makes echoing of keystrokes work correctly.

1991-07-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* eval.c (Finteractive_p): Changed "! XTYPE (foo) == Lisp_Bar" to
	"XTYPE (foo) != bar".

1991-07-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* eval.c (apply1): Don't forget to UNGCPRO before returning.

	* xterm.c (XTupdate_begin): Undisplay the cursor here; do_scrolling
	will call XTins_del_lines when the screen matrix is inaccurate, so
	we cannot undisplay the cursor then, but do_scrolling is always
	called within an update.

1991-07-10  David J. MacKenzie  (djm@nutrimat)

	* termcap.c, tparam.c [!emacs, USG || STDC_HEADERS]: Define bcopy
	in terms of memcpy.

1991-07-09  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* scroll.c (do_scrolling): Use correct termination condition for
	loop that uses the glyph pointers for the deleted lines to fill in
	the inserted lines.

1991-07-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* editfns.c: Doc fix.

1991-07-03  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* dispnew.c (line_hash_code): Test m->highlight[vpos], not
	m->highlight.  All lines were getting hash codes of -1, because
	the highlight vector was never NULL.  Golly.

	* process.c (list_processes_1): Handle status of network streams.

1991-07-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* doc.c (Fdocumentation_property):
	Pass only strings to Fsubstitute_command_keys.

1991-07-02  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* editfns.c (init_editfns): If neither of the environment
	variables are set, DON'T set Vuser_name to Vuser_real_name; it's
	supposed to reflect the EFFECTIVE uid.
	Get the full name according to Vuser_name if it differs from
	Vuser_real_name, not if they are equal.
	And pass Vuser_name to getpwnam in that case instead of user_name,
	which might be 0.

	* lisp.h (RETURN_UNGCPRO): New macro.

	* bytecode.c (Fbyte_code): Do not remove GC protection from the
	stack when making a function call, because the caller is
	responsible for protecting the arguments to a MANY-arg'ed
	function.
	* eval.c (Fapply): If we use funcall_args, GCPRO it.
	And when we call Ffuncall with funcall_args, tell it the correct
	length of funcall_args, no matter which branch allocated it.
	(Ffuncall): Don't gcpro the arguments before calling
	Fgarbage_collect.
	(Feval): If we're calling a subr that takes MANY args, don't
	UNGCPRO until after we call the subr.
	(apply1, call0, call1, call2, call3): GCPRO the arg arrays passed
	to Ffuncall and Fapply.
	* callproc.c (Fcall_process, Fcall_process_region): Don't GCPRO
	the argument array.
	* editfns.c (Finsert, Finsert_before_markers): Don't GCPRO the
	argument array.  Added comment about when GCPROing is not needed.
	* mocklisp.c (Finsert_string): Don't GCPRO the argument array.

	* keyboard.c (init_keyboard): Handle SIGQUIT with interrupt_signal
	on any system that has HAVE_TERMIO, not just on USG systems.

1991-07-01  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* editfns.c (init_editfns): Test that user_name isn't 0.

1991-06-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* search.c: Doc fixes.

1991-06-28  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keyboard.c (make_lispy_event): Let the posns of mouse clicks and
	mouse movements be nil when window_from_coordinates returns a
	NON-window, not when it returns a window.  Since posn is a lisp
	object, don't call make_number when consing up the event.
	Don't call make_number on the code member of the event.

	* keyboard.c (struct movement): Make the x, y, and time members
	Lisp_Objects, since it's easier to convert from a Lisp_Object than
	to.
	(note_mouse_position): Adjusted for the above.
	(make_lispy_event): Removed code to make Lisp_Objects for those
	members.

	* xterm.c (XTread_socket): When handling LeaveNotify events,
	remember that the focus member of the event is true when the
	receiving window now has the focus, not when it is losing it.
	* xfns.c (Ffocus_screen): Don't signal an error if SCREEN is
	already the focus screen.

1991-06-26  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* alloc.c (Fmake_rope): Use sizeof (GLYPH) instead of 2 to
	determine how large the string should be, and changed doc string
	to describe ropes as strings of glyphs, not just as strings of
	character pairs.
	(Frope_elt): Use sizeof (GLYPH) as the element size, instead of
	assuming that the elements are two bytes.
	* lisp.h (typedef GLYPH): Moved the definition from here...
	* config.h (typedef GLYPH): to here, so people can elect to get
	better performance if they don't want to use huge fonts.
	* xterm.c (dumpglyphs): Use XDrawImageString or
	XDrawImageString16, Depending on sizeof (GLYPH).

	* data.c (Fsetq_default): Call Fset_default to do the assignments,
	not plain Fset.

	The following changes were contributed by Jamie Zawinski
	<jwz@lucid.com>:

	* bytecode.c (Fbyte_code): BYTE_CODE_SAFE and BYTE_CODE_METER
	options added.
	Added Bmark, Bscan_buffer, Bset_mark to support error-checking for
	these obsolete bytecodes.
	Added Bunbind_all to support tail-call optimization (not yet
	implemented).
	Did NOT add the relative branch opcodes that were in the version
	of bytecode.c that Jamie sent.
	The branching bytecodes now only QUIT if they take the branch.
	Btemp_output_buffer_show, Bforward_char, Bforward_word,
	Bskip_chars_forward, Bskip_chars_backward, and Bforward_line
	passed the wrong number of arguments to their subrs.
	Brem, Bbuffer_substring, Bdelete_region, Bnarrow_to_region,
	Bstringeqlsign, Bstringlss, Bequal, Bnthcdr, Bmember, Bassq,
	Bsetcar, and Bsetcdr passed arguments to the subr in the wrong
	order.

1991-06-25  Jim Blandy  (jimb@churchy.gnu.ai.mit.edu)

	* doc.c (Fdocumentation): Added a QUIT test to the loop that finds
	the symbol's function value.

1991-06-24  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* xterm.c (dumprectangle): Removed call to XFlushQueue here.

	* keyboard.c (command_loop_1): Call Fselect_screen to establish
	the new selected screen after the key sequence has been read, not
	at the top of the loop.  This way, a key sequence will happen in
	the screen it was typed at, or (to be more precise) the screen its
	last character was typed at.

	* keyboard.c (fast_read_one_key): Function deleted, since it had
	been #if 0'd out a long time ago.
	(command_loop_1): Support for fast_read_one_key removed.

	* eval.c (Ffuncall): Do GCPRO the arguments, contrary to the May
	16 change.  The convention appears to be that the MANY-arged
	callee must protect its own arguments.
	(Fapply): Don't protect funcall_args; they are the caller's
	responsibility.
	* bytecode.c (Fbyte_code): GCPRO the section of the stack *above*
	the args to Ffuncall, since it will be protected again once
	Ffuncall returns and therefore should stay valid.  If it is not
	protected, string relocation may make it invalid.
	* mocklisp.c (Finsert_string): GCPRO the arguments, since insert
	may cause a garbage collection.
	* editfns.c (Finsert, Finsert_before_markers): GCPRO the
	arguments, since insert may cause a garbage collection.
	* callproc.c (Fcall_process, Fcall_process_region): GCPRO the
	arguments, since insert may cause a garbage collection.

1991-06-20  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* buffer.h (struct buffer_text, struct buffer): small change to
	comments.

	* search.c (Fmatch_beginning, Fmatch_end): Fixed doc strings to
	indicate that non-regexp searches set these too.

	* window.c (Fset_window_start): If window is not the selected
	window, set windows_or_buffers_changed, so that redisplay will
	know that it should redisplay the window.

	* callint.c (Finteractive): Changed doc string to indicate that
	the interactive prompts are passed through format.

1991-06-20  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

	* buffer.c (syms_of_buffer): buffer-undo-list doc fix.

1991-06-11  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

	* data.c (Fsetq_default): Take multiple SYM, VAL args; syntax now
	parallel to setq.

1991-05-25  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (kbd_buffer_read_char): Fix wait-for-input loop so
	that we always process/toss events we don't want to return.

        * screen.c (Fselect_screen): Call Ffocus_screen instead of
	x_new_selected_screen, which doesn't exist anymore.

	* xfns.c (Ffocus_screen): Declare the type of the SCREEN argument.

	* xfns.c (Fx_track_pointer): Function #if 0'd out - I don't think
	that this is a feature that we want.
	(syms_of_xfns): Elide the defsubr for the above.

	* xterm.c (x_mouse_screen, x_input_screen): Variable deleted,
	since all we really need is x_focus_screen; all other issues are
	the realm and responsibility of the window manager.
	(x_new_selected_screen): Renamed to x_new_focus_screen, and
	modified not to do thiogs inappropriate for signal handlers.
	(XTread_socket): Change the handling of EnterNotify, LeaveNotify,
	FocusOut and FocusIn events to use x_new_selected_screen, and
	ditched code that deals with x_mouse_screen and x_input_screen,
	since they don't exist anymore.
	(x_display_bar_cursor, x_display_box_cursor): Compare s with
	x_focus_screen to see what form the cursor should take.
	(x_destroy_window): Don't bother with x_input_screen.
	* xfns.c (x_mouse_screen): Removed extern declaration for this.
	(Fx_grab_pointer): Confine the pointer to x_focus_screen, not
	x_mouse_screen.  This is wrong, but will make emacs compile until
	this gets fixed.

1991-05-23  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (get_input_pending): Don't use trim_events; use
	readable_events instead.

	* keyboard.c (make_lispy_event): Remove case for window_sys_event,
	since that type of event doesn't exist anymore.

	* minibuf.c (Fcompleting_read): Document the backup-n argument.

	* dispnew.c (init_display): Don't declare alternate_display extern
	here.  I can't figure out what this feature is, and it's broken.
	* emacs.c (main): Don't test alternate_display and put its value
	in the environment.

1991-05-22  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (struct movement): Made .used an int instead of a
	char, since that's more likely to be stored atomically on SPARCS
	and similar machines.

	* termhooks.h (struct input_event): Removed the window_sys_event,
	since it's not used anywhere.  Added screen_selected event type.
	The event handling code used to change the current buffer,
	selected window, and selected screen out from under running lisp
	code.  Now we wait for a more convenient time by enqueuing an
	event.
	* xterm.c (XTread_socket): When handling FocusIn events and
	EnterNotify events with the focus member set, enqueue a
	selected_screen event instead of calling x_new_selected_screen.
	* keyboard.c (trim_events): Function deleted; it is a bad idea to
	delete events based on the current tracking state, since tracking
	might be re-enabled later.
	(readable_events): New function which searches the input queue for
	readable events.
	(tracking_off): Call readable_events to see if we should
	redisplay.
	(kbd_buffer_read_char):	Toss events that we are not interested in.
	This is a better place to do it than trim_events, since we know
	that do_mouse_tracking will not change.  Also, handle
	screen_selected events.
	(new_selected_screen): New variable, holding the screen which
	should become selected the next time through command_loop_1.
	(syms_of_keyboard): Initialize and staticpro new_selected_screen.
	(command_loop_1): If there is a new screen to be selected, do so.

1991-05-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xdisp.c (message): Removed the if at the top that did not
	display messages if the current screen was a termcap screen and a
	window system will be used.  The change to startup.el on May 18,
	1991 replaces this.

	* ralloc.c (check_memory_limits): If the address returned by the
	allocator is not representable in a Lisp_Object, call memory_full
	instead of printing a very silly "warning" message.

1991-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* xterm.c (XTread_socket): Don't overwrite the end of the buffer
	with function keys.

	* keyboard.c (tracking_off): Update input_pending after reading
	all the input.
	* process.c: #include "screen.h".
	(wait_reading_process_input): Check if any screens have been newly
	mapped and need updating.
	* xterm.c (XTread_socket): Don't SET_SCREEN_GARBAGED when the
	screen is unmapped; do this when is mapped.
	(dumprectangle): Don't dump any data for garbaged screens.

1991-05-18  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* sysdep.c (init_sys_modes): Moved the clauses that set up
	interrupt-driven input out of the "if running on a terminal"
	clause, since these may need to be set up even when running on a
	window system.

1991-05-17  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* process.c (Fprocess_status): For network connections, return
	Qopen and Qclosed instead of Qrun and Qexit, as documented.

	* lread.c (read1): Removed code that treated numbers starting with
	a zero as octal.

1991-05-16  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* eval.c (Ffuncall): Don't gcpro the arguments; the caller
	protects them.
	(Fapply): Gcpro funcall_args, if we use them.

	* xterm.c (notice_mouse_movement): #if 0'd this function out.
	(XTread_socket): #if 0 the code that fakes motion events for
	moving in and out of windows.  Also, rearrange the MotionNotify
	case to give character rows and columns to note_mouse_position,
	not pixel x and y positions.  Don't deal with scrollbars here.
	* termhooks.h (struct input_event): Removed the mouse_movement
	event kind.
	* keyboard.c (movement_buf): A new buffer for mouse-movement events.
	This is hairier than you might think; see the comments for this
	and the comments for note_mouse_position and get_mouse_position
	for an explanation of why this is hairy.
	(movement_ptr): Where the event handler should store new mouse
	locations.
	(EVENT_QUEUES_EMPTY): New macro, to be used in the places that
	used to compare kbd_fetch_ptr to kbd_store_ptr to see if there
	were any events available; this macro tests the mouse movement
	buffer too.
	(Qmouse_movement): New symbol to head mouse movement events with.
	(trim_events): Mouse movement events are no longer in kbd_buffer,
	so don't try to trim them.
	(tracking_off, kbd_buffer_read_char, get_input_pending): Use
	EVENT_QUEUES_EMPTY.
	(get_mouse_position): New function to retrieve a mouse position
	from the buffer properly, no matter when the event-handling signal
	occurs.
	(kbd_buffer_read_char): If there is something in kbd_buffer, make
	an event for that; if there is a mouse movement, make an event for
	that; otherwise, the while loop lied.
	(make_lispy_event): Added code to produce mouse movement events.
	(init_keyboard): Clear the mouse movement buffer.
	(Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
	Qexited_window, Qexited_scrollbar): Removed extern declarations
	for these, since they're no longer generated.
	(syms_of_keyboard): Initialize and staticpro Qmouse_movement,
	remove DEFVAR_LISP for Vignore_mouse_events.

1991-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* lread.c (read1): Correctly parenthesize the shift when parsing
	octal numbers, and signal an error if we see a non-octal digit.

1991-05-13  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (trim_events): New function, to remove uninteresting
	events from the input queue.
	(get_input_pending): Call trim_events before checking the queue,
	so as not to advertise input we don't care about.
	(Ftrack_mouse): A new function to enable mouse tracking for a
	block of code.
	(tracking_off): A function for unwind_protection; restore the
	mouse tracking state to what it was outside of the track-mouse
	(syms_of_keyboard): defsubr track-mouse.
	(make_lispy_event): Find the window io which the click occurred
	when processing mouse_click events, instead of trusting the window
	tree in the signal-handling code.  Include the buffer position in
	the click event.

	* xterm.c (construct_mouse_click): Return the click's screen, not
	its window, and don't bother updating Vmouse_window.  Calculate
	the row and column of text-area clicks using
	pixel_to_glyph_translation, since we know that those data
	structures are alive in signal handlers.

	* screen.c (window_from_coordinates,
	Flocate_window_from_coordinates): Moved these to window.c, since I
	need to be able to call them even if we don't have multi-screen
	support.
	(syms_of_screen): Removed defsubr for
	Flocate_window_from_coordinates.
	* window.c (window_from_coordinates, Flocate_window_from_coordinates):
	Here they are.
	(syms_of_window): Here is the defsubr.

	* keyboard.c (note_mouse_position): New function to enqueue
	mouse movement events properly.
	(current_movement_event): New variable, to support the above.  See
	its comment for more explanation.

	* termhooks.h (struct input_event): Change the .window member to
	.screen, make it a struct screen *, and indicate that those events
	which used to return	windows now return screens.  It is unsafe
	for the event reader to traverse the window structure, because it
	can be called by a signal handler.

1991-05-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keyboard.c (Vignore_mouse_events): Variable deleted.
	(make_lispy_event): For mouse and scrollbar clicks, return the
	position as a pair of numbers, not a list of two numbers.

1991-05-09  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* keyboard.c (do_mouse_tracking): Define this variable, which
	controls whether kbd_buffer_read_char will ignore button up and
	mouse movement events.
        * termhooks.h: Declare do_mouse_tracking here.

        * xterm.h (STANDARD_EVENT_SET): New constant, giving the event
	mask all the windows use.

	* xfns.c (Vx_send_mouse_movement_events): Removed this variable;
	XTmouse_tracking_enable and do_mouse_tracking do its job better.
	(syms_of_xfns): Remove the DEFVAR_LISP for the above.
	(x_window): Don't ask for any pointer motion events or button
	release events by default; use the unmodified STANDARD_EVENT_MASK.
	The user will ask for them explicitly if he or she wants them.
	And don't ask for backing store.

	* xterm.c (XTmouse_tracking_enable): New function to
	request/unrequest detailed mouse tracking information of the
	server, and set the flag used by XTread_socket.
	(x_term_init): Set mouse_tracking_enable_hook to
	XTmouse_tracking_enable here.
	(XTread_socket): Handle mouse movement events by calling
	note_mouse_position.

	* xterm.c (XTread_socket): For MapNotify events, go ahead and set
	the screen's visible flag, so Expose events will work.  Clear the
	iconified flag.

	* editfns.c (Finsert_char): Return immediately if n <= 0, not just
	if n < 0, so that the `while' below does not become an infinite
	loop.

	* term.c (mouse_tracking_enable_hook): Added this variable to
	allow emacs to request that the window system start or stop
	detailed mouse tracking.
	* termhooks.h (mouse_tracking_enable_hook): Declare it here.

	* xfns.c: Declare the functions before initializing
	x_screen_parm_table to point to them.

	* xterm.c (XTread_socket): Don't send Qmapped_screen,
	Qunmapped_screen, Qexited_scrollbar, Qexited_window,
	Qredraw_screen - these are not features that we want to support.

1991-05-07  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* editfns.c (Finsert_char): Let strlen be the minimum of n and
	256, not the maximum, so we use an n-byte buffer when n < 256, and
	a 256-byte buffer many times when n > 256.

1991-05-05  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keymap.c (Fkeymapp): Fixed docstring to give the right
	definition of a keymap.

1991-05-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* data.c (Fcompiled_function_p): New function.

1991-05-03  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* xfns.c (struct x_screen_parm_table): New type for recording
	information about screen parameters.
	(x_screen_parms): New table describing the existing parameters.
	(init_x_parm_symbols, x_set_screen_param): Use x_screen_parms
	instead of a large switch statement.
	(x_figure_window_size): Make the default case of the switch call
	abort instead of signalling an error, since window_prompting's
	value is internally generated.

1991-05-01  Jim Blandy  (jimb@churchy.gnu.ai.mit.edu)

	* keymap.c (describe_map_tree): GCPRO the maps variable;
	Fkey_description calls Fmapconcat, which eventually calls
	Ffuncall, which can garbage-collect.

1991-04-28  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* dispnew.c (buffer_posn_from_coords): Use the information in bufp
	to reduce the distance compute_motion must scan, when possible.

1991-04-27  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (syms_of_keyboard): Qtop_level is initialized and
	staticpro'd in syms_of_data too.  Don't staticpro (or initialize)
	it again here.

	* macros.c (syms_of_macros): Since executing-macro and
	executing-kbd-macro are actually the same variable, use
	DEFVAR_LISP_NOPRO for the second one so it doesn't get staticpro'd
	twice.

	* process.c (syms_of_process): Don't staticpro or initialize Qexit
	here, since syms_of_eval already does this and it's bad to
	staticpro something twice.
	(Qexit): Remove declaration here, so there will be a compilation
	error if someone rearranges eval.c without fixing the Qexit stuff.
	* eval.c (syms_of_eval): Add comment here to say that
	syms_of_process cares about Qexit too.

	* lread.c (init_obarray): Don't staticpro Vobarray, since the
	DEFVAR_LISP in syms_of_read takes care of that.

1991-04-22  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* window.c (save_window_save): Always get the selected window's
	value of point from its buffer, not just when it's also the
	current buffer.

	* lisp.h (Qdisabled): Declare this here so that the keys_of_*
	files can disable the commands they define.
	* casefiddle.c (keys_of_casefiddle): Make upcase-region and
	downcase-region disabled, by default.

1991-04-16  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* bytecode.c (PUSH):  Alliant can't be bothered to implement the
	preincrement operator right, so use a comma.

 	* print.c (syms_of_print): staticpro Qexternal_debugging_output.

	* editfns.c (clip_to_bounds): No longer static - used in window.c.
	* window.c (unshow_buffer): Use clip_to_bounds to make sure we
	change point to something legal.

1991-04-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* sysdep.c: Changes in formatting and comments.

1991-04-12  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* editfns.c (Fbuffer_substring): Don't call make_string, because
	it may cause a compaction and move the buffer, and then copy the
	wrong data.

	* keyboard.c (read_char): Only GC if we've actually done enough
	consing since the last gc to make it worthwhile.

1991-04-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

	* keymap.c (access_keymap): Canonicalize the order of the
	modifiers when you look up a symbol in a keymap, too.
	(where-is-internal): If the keymap in which we found the
	definition was reached by meta-prefix-char, replace it with the
	metized character.

	* eval.c (Fcondition_case): Initialize the `handler_list' member
	of the catchtag.

	* keyboard.c (read_char): reset recent_keys_index when it is
	greater than OR EQUAL to the number of elements in recent_keys,
	stupid.

	* keymap.c (access_keymap): When fetching the car of listy events,
	no need to call Fcar_safe - extract the car directly.
	* keyboard.c (read_key_sequence): Don't extract the car from listy
	events here since 1) it strips information that we need from the
	events, and 2) access_keymap will take care of that for us.

	* macros.c (Qexecute_kbd_macro): New variable, used by
	Fexecute_command.
	(syms_of_macros): Initialize and staticpro Qexecute_kbd_macro.
	* lisp.h: Add extern declaration for Qexecute_kbd_macro.
	* keyboard.c (Fcommand_execute): Add an entry to the command
	history for keyboard macros too.

	* xterm.c (XTread_socket): If we get a MappingNotify event whose
	request == MappingKeyboard, someone has changed the keyboard
	mapping, and we should get the new mapping with
	XRefreshKeyboardMapping.

1991-04-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

	* commands.h: Declare last_command_char to be a Lisp_Object, not
	an integer (ack).

	* cmds.c (Fself_insert_command): If last_command_char is not an
	integer, beep.
	* minibuf.c (Fself_insert_and_exit): Same thing.

	* keyboard.c (format_modifiers): New function, factoring out code
	from modify_event_symbol and reorder_modifiers.
	(modify_event_symbol): Call format_modifiers instead of doing the
	work inline.
	(reorder_modifiers): New function to put the modifiers on a
	modified symbol in the canonical order.

	* keymap.c (modify_event_symbol): Prepend the modifiers so they
	appear in the canonical order: `M-C-S-U-'.
	(store_in_keymap): If IDX is a symbol, put the modifiers in the
	canonical order before storing.

1991-04-09  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keymap.c (Flocal_set_key, Fglobal_set_key): When checking types
	of arguments, allow KEYS to be a vector or string, not just a
	string.
	(keymap_table): New static function to replace duplicated code in
	access_keymap and store_in_keymap.
	(access_keymap): Use keymap_table.
	(store_in_keymap): Use keymap_table, and put non-character
	definitions in dense keymaps *after* the vector.

	* fileio.c (directory_file_name): Remove trailing slashes from
	single-letter names like "a/" too.  Let slen be the string length,
	not one less than the string length.

	* keyboard.c (Fset_input_mode): Don't complain that QUIT isn't an
	ASCII character if it is nil - it is an optional parameter.

	* keymap.c (Faccessible_keymaps): Use meta-characters in the key
	sequences returned, carefully making sure that the sequences still
	appear in order of increasing length.

1991-04-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* vmsfns.c (vms_trnlog): Increased size of str to 256 elements.
	(vms_symbol): Increased size of str to 1025 elements.

1991-03-24  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* dispnew.c (pixel_to_glyph_translation): Moved this function to
	xterm.c, since it is specific to X and only called by the X code.
	* xterm.c (pixel_to_glyph_translation): Here it is.

1991-03-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* s-usg5-4.h (DATA_SEG_BITS): Definition deleted.
	* m-intel386.h (DATA_SEG_BITS): Define here if USG5_4.

1991-03-22  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keymap.c (Faccessible_keymaps): Produce meta-characters in the
	key sequences instead of [meta-prefix-char CHAR] sequences.

1991-03-21  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keymap.c (Flookup_key): If KEY is a zero-length array, then
	return KEYMAP; this is more algebraically satisfying.

	* dispnew.c (Fsit_for): If the time to sit is zero and there is no
	input available, then return Qt, not Qnil.

	* keyboard.c (read_char): If a quit occurs and we return
	quit_char, clear Vquit_flag, so we don't end up returning it again
	and again...  All lisp code does this manually if they call
	read-char with quits inhibited, so it's the right thing to do.

1991-03-20  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (read_char): If there is still no input available
	after an auto-save, do a garbage-collection.

	* undo.c (truncate_undo_list): Always leave at least one undo
	record in the undo list.  And use sizeof (struct Lisp_Cons), etc.
	instead of 8, etc.

	* keyboard.c (read_char): When deciding whether to wrap
	recent_keys_index back to 0, compare it against
	sizeof (recent_keys)/sizeof(recent_keys[0]),
	not sizeof (recent_keys).
	(quit_char): This can't be anything but an ASCII character, so it
	shouldn't be a Lisp_Object.  The declaration's comment says why.
	(read_char, init_keyboard): Treat quit_char as an int now.
	(Fset_input_mode): As above, and signal an error if QUIT is not an
	ASCII character.

	* callint.c (Fprefix_numeric_value): Use XFASTINT to initialize
	val, not raw.

	* fileio.c (Fmake_symbolic_link): Don't expand FILENAME; this
	would make it impossible to make a link to a relative name.

1991-03-19  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

	* keyboard.c (syms_of_keyboard): Removed the DEFVAR_BOOL for
	meta-flag.  This cannot be a lisp variable because we need to
	change the terminal settings whenever this flag changes.  Change
	this through set-input-mode instead.

1991-03-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* keyboard.c (read_avail_input): Raise SIGHUP if no input on AIX.

1991-03-19  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* keyboard.c (kbd_buffer_store_event, kbd_buffer_read_char,
	read_key_sequence, Fexecute_extended_command, Fset_input_mode,
	init_keyboard, syms_of_keyboard): Use XSET (var, Lisp_Int, exp)
	instead of XSETINT (var, exp) in those cases where var is not
	known to already be a Lisp_Int.
	* search.c (skip_chars): Same.
	* xterm.c (construct_mouse_click, XTread_socket): Same.
	* callint.c (Fprefix_numeric_value): Make sure to return a
	Lisp_Int even when RAW is a cons whose car is not a Lisp_Int.
	* process.c (sigchld_handler): When searching for a process whose
	pid is -1, make sure that the pid is an int first, since network
	streams are in Vprocess_alist too.

	* keyboard.c (syms_of_keyboard): Added DEFVAR_BOOL for
	meta-flag.  Emacs 18 had this, and I see no entry in the ChangeLog
	saying that it was purposefully removed.

1991-03-17  Jim Blandy  (jimb@geech.ai.mit.edu)

	* keymap.c (Fcopy_keymap, Faccessible_keymaps, describe_map,
	append_key): Minor typos and brainos corrected.

	* keyboard.c (read_char): Removed code to find the vector in a
	(kbd-macro . VECTOR) - style macro, since the macro is represented
	by the vector itself.
	(read_char_menu_prompt): Changed to correctly recognize the new
	dense keymap structures.
	(read_key_sequence): Changed code that checks for keymapness to
	use get_keymap_1 instead of doing the indirection and keymapness
	testing itself.
	(Fcommand_execute): A keyboard macro is now a string or a vector.
	(Fexecute_extended_command): When expanding this_command_keys,
	remember that it is now an array of Lisp_Objects, not chars.

	* doc.c (Fdocumentation): Rearranged into a switch statement, and
	made vectors macros, not keymaps.

	* eval.c (Fcommandp): Removed code to recognize
	(kbd-macro . VECTOR) as a command, and added code to recognize
	vectors as commands.
	* macros.c (Qkbd_macro): Variable deleted.
	(syms_of_macros): Initialization of Qkbd_macro removed.

1991-03-14  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* minibuf.c (keys_of_minibuf): Changed all calls to
	initial_define_lisp_key to calls to initial_define_key.

	* keymap.c (describe_map): Adjusted to handle the new style of
	keymap.

1991-03-14  Richard Stallman  (rms@mole.ai.mit.edu)

	* fileio.c (Fwrite_region): On VMS, don't try rewriting old version.

1991-03-14  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* keymap.c (Faccessible_keymaps): Adjusted to handle the new style
	of keymap.
	(Fwhere_is_internal): Handle the new-style of keymaps.
	Additionally, only check to see if a match is shadowed by a
	binding in the local keymap when LOCAL_KEYMAP is non-nil, instead
	of comparing elt against DEFINITION yet again.
	(describe_map_tree): Handle key sequences that are vectors, as
	well as those that are strings.

1991-03-13  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* commands.h, keymap.c (meta_map, control_x_map): Make these
	Lisp_Objects, not Lisp_Vectors.
	keymap.c (syms_of_keymap): Same.

	* keymap.c (Fuse_global_map): There is no longer any reason to
	insist that KEYMAP must be a dense keymap; delete the code that
	does so.

1991-03-12  Jim Blandy  (jimb@wookumz.ai.mit.edu)

	* commands.h, lisp.h: Changed global_map and current_global_map	to
	be Lisp_Objects, not Lisp_Vectors.
	keyboard.c (read_key_sequence): Same.
	keymap.c (Fkey_binding, Fglobal_key_binding, Fglobal_set_key,
	Fuse_global_map, Fwhere_is_internal, describe_buffer_bindings,
	syms_of_keymap): Same.

	* keymap.c (Fdefine_key): Braino: increment idx and clear metized
	flag even when the element of the key sequence isn't a character.
	(Flookup_key): Fix same braino.

1991-03-10  Jim Blandy  (jimb@wookumz.ai.mit.edu)

	* keymap.c (get_keyelt): Use access_keymap to resolve indirect
	entries, instead of duplicating its code.
	(Fcopy_keymap): Handle the new keymap structure.

1991-03-09  Richard Stallman  (rms@mole.ai.mit.edu)

	* eval.c (struct catchtag): New field handlerlist.
	(internal_catch, internal_condition_case): Set that field.
	(unbind_catch): Use it.

1991-03-08  Richard Stallman  (rms@mole.ai.mit.edu)

	* m-intel386.h (signal): Maybe define if USG.

	* keyboard.c (echo_char): Don't have space at end of echobuf.

1991-03-07  Jim Blandy  (jimb@albert.ai.mit.edu)

	* keyboard.c (syms_of_keyboard): Initialize mouse_syms, instead of
	doing func_key_syms twice.  Don't deal with scrollbar_syms, since
	it doesn't exist.

1991-03-06  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* keymap.c (access_keymap, store_in_keymap): Changed to handle the
	new style of keymaps.

	* fns.c (Fassq, Fcopy_alist): Changed docstring to promise to
	ignore elements of LIST that are not conses.  See access_keymap
	and copy_keymap for a cheap excuse.

1991-03-06  Richard Stallman  (rms@mole.ai.mit.edu)

	* s-vms.h (DATA_START): Remove `+ 512'.

1991-03-05  Jim Blandy  (jimb@spiff.ai.mit.edu)

	* keymap.c (Fmake_keymap): Rewritten to construct the
	new dense keymap structure: (keymap VECTOR . ALIST).  Docstring
	adjusted accordingly.  This means that the keyboard macro
	stupidity (see Feb 27, keyboard.c) is no longer needed.

1991-03-03  Richard Stallman  (rms@mole.ai.mit.edu)

	* sysdep.c (MEMORY_IN_STRING_H): New compilation flag.
	* s-isc2-2.h: New file.

1991-02-27  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* macros.c (Qkbd_macro): New variable, to hold the symbol
	`kbd-macro', which we use to tag vector-style keyboard macros.
	(syms_of_macros): Initialize and staticpro Qkbd_macro.

	* eval.c (Fcommandp): Recognize the new keyboard macros.

	* keyboard.c (Fcommand_execute): A keyboard macro is now a string,
	or a cons whose car is the symbol `kbd-macro' and whose
	cdr is a vector of events; previously, macros were strings or
	vectors, but that makes it difficult to tell the difference
	between macros and dense keymaps.
	(read_char): Handle the new macros correctly, and re-allocate
	this_command_keys correctly.

1991-02-26  Richard Stallman  (rms@mole.ai.mit.edu)

	* s-vms.h (calloc): Define like malloc, etc.

1991-02-26  Jim Blandy  (jimb@spiff.ai.mit.edu)

	* xterm.c (XTread_socket): Move enter_timestamp outside of the
	function; static variables inside functions don't always work in
	Emacs.

	* editfns.c (in_accessible_range): Deleted - insufficently
	general.
	(clip_to_bounds): New function, much like in_accessible_range,
	except that the upper and lower bounds are arguments.
	(goto_char, save_restriction_restore): Rewritten to use
	clip_to_bounds instead of in_accessible_range.

1991-02-25  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* keymap.c (initial_define_lisp_key): Turn KEY into a Lisp_Int
	before passing it to store_in_keymap.

	* buffer.c (reset_buffer_local_variables): Don't try to initialize
	the buffer's mouse_map and function_key_map fields, since they
	don't exist anymore.

	* macro.c (kbd_macro_buffer, kbd_macro_ptr, kbd_macro_end): These
	are now all pointers to Lisp_Objects instead of chars.
	(Fend_kbd_macro): Use make_sequence.
	(store_kbd_macro_char): Argument c is now a Lisp_Object.  Change
	call to xrealloc to ask for Lisp_Objects instead of chars.  Set
	kbd_macro_end to the same place in the new buffer as it was in the
	old one, not to the end of the buffer.
	(Fexecute_kbd_macro): Allow MACRO to be a string or a vector.
	(syms_of_macros): Allocate Lisp_Objects instead of chars for
	kbd_macro_buffer.

	* alloc.c (make_sequence): New function, useful to keyboard.c and
	macro.c.
	* keyboard.c (Fread_key_sequence): Use make_sequence.
	(Fthis_command_keys): Use make_sequence.

1991-02-24  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* keymap.c (Fwhere_is): If the command can't be found, the message
	is now "foobie is not on any key.", instead of "... any keys.".

	* keyboard.c (input_poll_signal): Pass 0 to read_avail_input,
	instead of `&junk'.  Removed variable `junk'.
	(command_loop_1): Updated to handle the unified function key/mouse
	event/keystroke arrangement.
	(Finput_pending_p): Removed vestiges of code to handle
	unread_input_char value of -1, since this doesn't happen anymore.
	(read_char): Adapted to handle lispy events.
	(read_char_menu_prompt): Allocate `menu' buffer using alloca,
	instead of a variable-sized array, which is gcc-specific.
	(Frecent_keys): Return the most recent "keystrokes" as a vector,
	to accomodate lispy events.
	(Fset_input_mode): Accomodate non-characters as quit keys.  If
	this is a bad thing, init_sys_modes will tell us.
	(init_keyboard): this_command_keys is now an array of
	Lisp_Objects; adjust the amount of storage we request to hold it.
	Remember that quit_char can be any keystroke.
	(syms_of_keyboard): last_command_char, last_input_char, help_char,
	menu_prompt_more_char and meta_prefix_char are now DEFVAR_LISPs
	instead of DEFVAR_INTs.

1991-02-24  Richard Stallman  (rms@mole.ai.mit.edu)

	* process.c (wait_reading_process_input): Use NETCONN_P.

1991-02-23  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* keyboard.c: (recent_keys, this_command_keys,
	menu_prompt_more_char, help_char, last_command_char, quit_char,
	last_input_char): Changed to Lisp_Objects, so we can use function
	keys for them.
	(Vglobal_function_map): Variable deleted.
	(echo_char): Echo function keys too.  The argument C is now a
	Lisp_Object instead of a char.
	(Fread_key_sequence): Removed sludge to handle window events
	specially, and added sludge to handle sequences with
	non-characters in them.
	(classify_object): Elided, since this should go away soon.
	(read_key_sequence): Adapted to look up symbols in keymaps,
	just like characters.

1991-02-23  Richard Stallman  (rms@mole.ai.mit.edu)

	* process.c (send_process): Handle EAGAIN like EWOULDBLOCK.

1991-02-22  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* doc.c (substitute_command_keys): Call describe_map_tree with
	only three arguments, since the CHARTAB arg has been disposed of.

	* keymap.c (Fcurrent_global_map, Fuse_local_mouse_map): Functions
	deleted, since the mouse maps are no longer separate from the key
	maps.
	(append_key): New function, which handles tacking a single
	keystroke on the end of a key sequence, promoting strings to
	vectors when needed.
	(Faccessible_keymaps): Adjusted to return vectors for key
	sequences, when necessary.
	(Fkey_description): Removed stuff to handle mouse buttons and
	other things specially, since this work will go into
	Fsingle_key_description.
	(Fsingle_key_description): SIMPLIFIED to handle everything
	correctly!  Jeepers!
	(Fwhere_is_internal): Scan the assoc-list at the end of dense
	keymaps, and construct strings or vectors.
	(where_is_string, describe_buffer_bindings): Simplified by
	deleting code to handle mouse button bindings specially.
	(describe_map_tree): Removed CHARTAB argument; this was
	a kludge to print out mouse events nicely, and is no longer
	necessary.  Nobody was using it anyway.
	(describe_map): Removed ugly hack to handle mouse buttons
	specially, added code to describe alists on dense keymaps, and
	removed CHARTAB argument.
	(describe_alist): Made to handle bindings of symbols as well as
	characters.  Removed CHARTAB argument.
	(describe_vector): Removed CHARTAB argument, allocated KLUDGE
	outside of loop and GCPRO'd it.
	(syms_of_keymap): Remove last vestiges of Vglobal_mouse_map,
	Vmouse_button_names, Suse_local_mouse_map,
	Scurrent_local_mouse_map.

	* buffer.h (struct buffer): Removed mouse_map and function_key_map
	members, since they are now handled by the keymap element.

	* keyboard.c (syms_of_keyboard): Change initialization of
	meta_prefix_char, since it's now a Lisp_Object.

	* keymap.c (Fkeymapp): Rewrote this to use get_keymap_1; now it's
	a one-liner instead of a 13-liner.
	(DENSE_TABLE_SIZE): Created new constant for the # of lookup-style
	entries in a dense keymap, and the index of the map's assoc list.
	Used it where appropriate.
	(Fcopy_keymap): Notice that 129'th element in dense keymaps.
	(Fdefine_key, Flookup_key): Reworked to deal with vectors of
	symbols and characters as well as strings for key sequences.
	(meta_prefix_char): Changed from an int to a Lisp_Object.

1991-02-21  Richard Stallman  (rms@mole.ai.mit.edu)

	* fileio.c (report_file_error): Don't downcase "I/O".

1991-02-20  Jim Blandy  (jimb@geech.ai.mit.edu)

	* keymap.c (access_keymap): Allow IDX to be any sort of bindable
	event, and deal with the extended keymaps.  IDX is now a
	Lisp_Object instead of an int, obviously.
	(store_in_keymap): Allow IDX to be any sort of bindable event, and
	deal with the extended keymaps.  IDX is now a Lisp_Object.

	* xterm.c (construct_mouse_click): Add code to set the up_modifier
	bit for ButtonRelease events.

	* keyboard.c (kbd_buffer_store_event): Use XFASTINT and XSETINT to
	access event->code, since it's a Lisp_Object.
	(kbd_buffer_read_char): Golly, perhaps we should increment
	kbd_fetch_ptr to remove the event we just read from the queue.
	(modify_event_symbol): Stupid fixes: correctly look up unmodified
	symbols when cache entry has a modified symbol vector.  And, when
	first adding the modified symbol vector, copy the old slot value
	into it correctly.

1991-02-19  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* keyboard.c (command_loop_1): #if 0 the block of code which
	handles mouse events and other lispy events specially, since I
	hope it will go away soon.

	* dispnew.c (Fsleep_for_millisecs): Pass all four arguments to
	wait_reading_process_input, instead of just the first two.

	* process.c (wait_reading_process_input): Remove support for
	only waiting for mouse input, since that has been superceded.
	This removes X dependencies from process.c, and eliminates some
	references to code that should only exist when using X10.

	* keyboard.c (mouse_moved_symbol, redraw_screen_symbol,
	mapped_screen_symbol, unmapped_screen_symbol,
	exited_window_symbol, exited_scrollbar_symbol): Renamed to
	Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
	Qexited_window, Qexited_scrollbar, just as done in xterm.c.
	(classify_object): Removed code to look up a function key in the
	global and local function key keymaps, since this will be done
	more generally.
	(Fexecute_mouse_event): Elided this function with a #if 0;  I
	think it will go away once the more general keymap stuff is
	implemented, but I'm not sure.
	(syms_of_keyboard): Removed defsubr for Sexecute_mouse_event.
	(where_is_string, describe_buffer_bindings, syms_of_keymap):
	Elided code to handle mouse button bindings specially; I hope this
	will go away.

	* lread.c (syms_of_lread): Change defsubr for eval-buffer to
	defsubr for eval-current-buffer.

	* keymap.c (syms_of_keymap): defvar for Vglobal_function_map
	removed, since that variable has disappeared.

	* xterm.c (x_func_key_to_sym): Removed entirely, since we no
	longer convert X keycodes to symbols in this section of code.
	(x_convert_modifiers): New function to turn the X modifier bits
	into struct input_event modifier bits.
	(encode_mouse_button): removed, since this work isn't done here
	anymore.
	(Vx_send_mouse_movement_events): Add an extern declaration for
	this.

	* termhooks.h: Only define struct input_event if the module
	has previously #included lisp.h; this avoids forcing simple modules
	like cm.c to #include lisp.h.

	* term.c: #include "lisp.h" before #including "termhooks.h", since
	the latter uses Lisp_Objects now.

	* xfns.c (syms_of_xfns): Delete the defsubr for Sx_window_id,
	since Fx_window_id is gone.

	* xterm.c (construct_mouse_event): Construct a struct input_event
	instead of a lispy event.

	* screen.c (coordinates_in_window):  Added explanatory comment.
	(window_from_coordinates): Change PART, whose returned values are
	dependent on X-windows, to be called MODELINE_P, with appropriate
	new return values.
	* xterm.c (notice_mouse_movement): Handle the X-windows dependent
	stuff that used to be in window_from_coordinates here instead.
	(XTread_socket): Modified to produce struct input_events
	instead of lispy events.

1991-02-18  Jim Blandy  (jimb@pogo.ai.mit.edu)

        * termhooks.h: Added up_modifier to the enum for modifier bits;
	this bit will be applied to mouse events.
	(struct input_event): Changed specification of non_ascii_keystroke
	events to send the function key number instead of a symbol.
	* keyboard.c (modify_event_symbol): Re-arranged to work well
	with function key/mouse button numbers instead of symbols.
	And if (MODIFIERS & up_modifer), prepend "U-" to the name of the
	symbol being constructed.
	(make_lispy_event): Use the new modify_event_symbol.

	* xterm.c (notice_mouse_movement): Adjusted this function to
	work with a struct input_event instead of producing an
	s-expression.

	* xterm.c, xfns.c: Made all references to x_mouse_queue,
	x_expose_queue, and the functions which manipulate them
	conditional on having X10, since only X10 code ever places
	anything in these queues.

1991-02-15  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* termhooks.h: Define struct input_event, to represent input
	events while they sit in the keyboard input buffer.  Using lisp
	objects to represent input events is a bad idea because the
	routines which enqueue them can be called from signal handlers,
	and therefore should not cons.

	* keyboard.c: (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Change
	these to be of type `struct input_event *'.
	(kbd_buffer_store_event): Manipulate struct input_events instead
	of lisp objects.
	(make_lispy_event): New function, to construct a lisp-style event
	corresponding to a particular struct input_event.
	(modify_event_symbol): New function, to add modifier prefixes to a
	symbol, and look the new symbols up quickly if they've already
	been created.
	(kbd_buffer_read_char): Call make_lispy_event to turn the thing
	in the keyboard buffer into the form that read_char is expecting.
	(Qwith_modifier_keys): Define this new symbol variable.
	(syms_of_keyboard): Initialize and protect Qwith_modifier_keys.

	* xterm.c (init_input_symbols): Rearranged the code that produces
	the func_key_syms array.
	(x_func_key_to_sym): Simplified, since more will be handled in
	make_lispy_event.
	(XTread_socket): When handling KeyPress events, don't pass the
	state of the modifier keys to x_func_key_to_sym, since it doesn't
	care any more.

	* sysdep.c (kbd_input_ast, end_kbd_input, read_input_waiting):
	Rename kbd_buffer_store_char to kbd_buffer_store_event.

	* keyboard.c (stuff_buffered_input): Since the keyboard buffer
	holds lisp objects, only stuff entries that are Lisp_Ints, and
	XINT them before passing them to stuff_char.
	(kbd_buffer_store_char): Make this not a static function, since
	sysdep.c calls it.  And rename it kbd_buffer_store_event.

	* keyboard.c (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Made these
	variables static, to document the fact that they're only used
	within keyboard.c.

1991-02-13  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* xterm.c (init_input_symbols): remove the `xk-' prefix from all
	the function key symbols, since they're going to be used for
	function keys from all sorts of terminals, not just when running
	under X.

	* lread.c (read_escape): Removed support for mouse button escapes
	(\S-, \U-, \C- applied to digits), because they're being replaced
	by something more rational.

1991-02-09  Richard Stallman  (rms@mole.ai.mit.edu)

	* buffer.c: Doc fix.

	* sysdep.c (dup2): Rewrite of non-F_DUPFD case.

1991-02-08  Richard Stallman  (rms@mole.ai.mit.edu)

	* m-intel386.h (LOAD_AVE_CVT): Add extra parens.
	* s-usg5-4.h (LIBX11_SYSTEM): #undef it.

1991-02-07  Richard Stallman  (rms@mole.ai.mit.edu)

	* s-esix.h: New version from kayvan.
	Adds HAVE_X11 conditional, NEED_PTEM_H, USG_SYS_TIME, USE_UTIME,
	LIBS_DEBUG; removes #undef sigsetmask, LIBS_SYSTEM, ESIX,
	MISSING_UTIMES.

1991-02-06  Richard Stallman  (rms@mole.ai.mit.edu)

	* process.c (Faccept_process_output): Second arg gives timeout.

1991-02-06  Jim Blandy  (jimb@geech.ai.mit.edu)

	* lread.c (read_escape): Added support for \S- and \U- escapes (for
	binding mouse buttons), and noted that \C- must work on digits.

	* xterm.c (init_input_symbols): Was mistakenly renamed
	init_inputs; named back.

	* xterm.c (construct_mouse_click, encode_mouse_button): Rewritten
	to build new-style mouse events.

	* dispnew.c (update_line): Write a zero into obody[olen] to make
	sure the lines in current_screen->glyphs remain terminated.
	* xdisp.c (display_string, display_text_line): Don't write off
	the end of the line and destroy the zero terminator when expanding
	a tab.

	* fns.c (Fy_or_n_p): Accept C-] (usually abort-recursive-edit) as
	well as C-g to quit.

1991-02-05  Jim Blandy  (jimb@geech.ai.mit.edu)

	* sysdep.c, s-aix3-1.h, s-hpux.h, s-iris3-5.h, s-iris3-6.h,
	s-irix3-3.h, s-rtu.h, s-sunos4-1.h, s-unipl5-0.h, s-unipl5-2.h,
	s-usg5-0.h, s-usg5-2-2.h, s-usg5-2.h, s-usg5-3.h, s-xenix.h:
	Globally replaced INTERRUPTABLE with INTERRUPTIBLE.

	* xterm.c (construct_mouse_event): Renamed to
	construct_mouse_click, since there are kinds of mouse events
	besides clicks (movement, for example).
	(XTread_socket): rename calls here.

	* xterm.c (mapped_screen_symbol, unmapped_screen_symbol,
	exited_scrollbar_symbol, exited_window_symbol,
	redraw_screen_symbol, mouse_moved_symbol): Renamed to
	Qmapped_screen, Qunmapped_screen, Qexited_scrollbar,
	Qexited_window, Qredraw_screen, Qmouse_moved, to agree with naming
	conventions elsewhere in Emacs.

	* xfns.c (text_part_sym, modeline_part_sym,
	vertical_scrollbar_sym, vertical_slider_sym, vertical_thumbup_sym,
	vertical_thumbdown_sym, horizontal_scrollbar_sym,
	horizontal_slider_sym, horizontal_thumbleft_sym,
	horizontal_thumbright_sym): Renamed to Qtext_part, Qmodeline_part,
	Qvscrollbar_part, Qvslider_part, Qvthumbup_part, Qvthumbdown_part,
	Qhscrollbar_part, Qhslider_part, Qhthumbleft_part,
	Qhthumbright_part, to agree with the naming conventions elsewhere
	in Emacs.

	* xterm.c (XTread_socket): While handling EnterNotify events,
	clear Vmouse_event here.
	(notice_mouse_movement): Don't clear it here.

1991-02-04  Richard Stallman  (rms@mole.ai.mit.edu)

	* s-sunos4-0.h: Renamed from s-sunos4.h.
	(read, write, open, close): Macro defs moved to s-sunos4-1.h.
	(INTERRUPTABLE_*): Likewise.
	* s-sunos4-1.h: New file.

1991-02-04  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* keymap.c (Vglobal_mouse_map, Vglobal_function_map): Variables
	removed in preparation for conversion to unified keymap format.
	(Fmake_keymap): Make vector keymaps with 129 entries; the last
	will be an assoc-list for looking up symbols.  Update docstring to
	describe 129'th element.
	(Fmake_sparse_keymap): Update docstring to say that you can bind
	symbols in these maps too.
	(Fkeymapp): Recognize 129-element vectors as keymaps, not
	128-element vectors.
	(get_keymap_1): wrong_type_argument can no longer return a new
	value supplied by the debugger; remove loop to support this.

	* xterm.c (XTread_socket): When handling EnterNotify events,
	enqueue fake mouse events iff Vx_send_mouse_movement_events !=
	Qnil.

	* xfns.c (Fx_window_id): Function removed; Fscreen_parameters
	already provides this information.

	* xterm.c (x_term_init): Cleaned up the code to get the host name,
	and removed fixed limit on host name length.

	* window.c (Fscroll_other_window): Don't explicitly save
	current_buffer and point; the save_excursion will take care of
	that anyway.

	* dispnew.c (safe_bcopy): Rewritten to handle overlapping regions
	with multiple calls to bcopy instead of a stupid copy loop.

	* xterm.c, xfns.c (Vscreen_part, Vx_send_movement_events): These
	variables renamed to Vmouse_screen_part,
	Vx_send_mouse_movement_events.

	* lread.c (Feval_buffer): function deleted.
	(Feval_current_buffer): Removed "#if 0 ... #endif" around this
	function.

1991-02-03  Richard Stallman  (rms@mole.ai.mit.edu)

	* Makefile, ymakefile (SHELL): Force use of sh.

	* s-usg5-4.h (USG5_4): Define it.
	(LOAD_AVE_*): Don't define them.
	* m-intel386.h (LOAD_AVE_*): Define, if USG5_4.

	* buffer.c (Fbuffer_local_variables): Omit slots with no names.

1991-02-03  Jim Blandy  (jimb@geech.ai.mit.edu)

	* xterm.c (x_term_init, init_input_symbols): Moved these to the
	bottom of the file, 1) to be consistent with the other files, and
	2) so it can initialize some variables I want.

1991-02-02  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* xterm.h: Added external declaration for x_focus_screen.

	* search.h: File deleted.
	* buffer.h: declare searchbuf here instead.

	* screen.c (Ffocus_screen, Funfocus_screen): Moved these functions
	to xfns.c, since they're x-specific.
	(syms_of_screen): Removed defsubr calls for above.
	* xfns.c (Ffocus_screen, Funfocus_screen): Here they are.
	(syms_of_xfns): The defsubrs are here now.

	* buffer.h (PT): Make this expand to an expression which is not an
	l-value, to prevent people from assigning to it.  If everyplace
	uses SET_PT, it will be easier to merge in the interval code.
	(point): Similar changes here.
	(SET_PT): This can no longer be written in terms of PT, so write
	out current_buffer->text.pt.

	* xterm.c (x_new_font): Rewritten to remove arbitrary limit on
	size of x_font_table.
	(x_font_table_size): Created new variable.
	(n_available_fonts, font_names, font_info, MAX_FONTS): Deleted
	these variables/macros.

	* dispnew.c (scroll_screen_lines): Instead of disabling the lines
	vacated by the scroll (i.e. zeroing enable), mark them as enabled
	but empty.

	* callint.c (Fcall_interactively): Move UNGCPRO down, so that
	stuff is protected while we build the command history entry and do
	the function call.

	* xterm.c (XTupdate_end): Turn cursor on, even if we don't
	currently have the focus.

	* minibuf.c (temp_echo_area_glyphs): Clear echo_area_glyphs and
	previous_echo_glyphs, so the message we're displaying will
	supercede any existing message.

	* keyboard.c: Removed external declaration of echo_area_glyphs,
	since it's declared in window.h.

1991-01-31  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* xterm.c (XRINGBELL): Pass 0 as the second argument to XBell;
	respect the user's preferences.

1991-01-30  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* xterm.c (x_draw_single_glyph): New function, created to simplify
	cursor drawing/undrawing.
	(x_display_box_cursor): Rewritten to properly handle the box
	cursor in its filled and hollow forms.
	* xterm.h (enum text_cursor_kinds): Added enum for the different
	kinds of cursors which might be displayed in a window.
	(struct x_display): added member `text_cursor_kind' which says
	which kind of cursor is currently being displayed in the window, so
	we can arrange to redraw it effectively.

	* keyboard.c (command_loop_1): When handling the forward_char
	command, don't let point move to the location after the end of the
	buffer.

	* keyboard.c (poll_suppress_count): Define this even if
	POLL_FOR_INPUT is not defined, because this makes lots of #ifdef
	clauses unnecessary, and doesn't hurt, because
	{start,stop}_polling become nops.

	* config.h, config.h-dist: Make these #include "system.h" and
	"machine.h", and let the config script link these appropriately,
	instead of using the machine-specific names and expecting the user
	to edit this file.

1991-01-29  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* window.c (Fdelete_window): sib is a Lisp_Object; treat it as
	such.

	* xterm.c (screen_unhighlight): When the focus leaves a screen,
	draw the cursor as a box instead of making it disappear entirely.

1991-01-29  Richard Stallman  (rms@mole.ai.mit.edu)

	* unexec.c (make_hdr) [TPIX]: Set f_hdr.f_nscns and f_thdr.f_scnptr.

	* sysdep.c [BROKEN_TIOCGWINSZ]: Undef TIOCGWINSZ.

	* process.c (wait_reading_process_input): Don't ignore
	a zero-length read on a network connection.  Do close it.

	* sysdep.c (hft_init, hft_reset): Pass &junk as arg to HFQERROR.
	Do nothing if not HFT.

1991-01-29  Jim Blandy  (jimb@albert.ai.mit.edu)

	* xfns.h: Created, to declare things defined in xfns.c.
	Declare Vx_send_movement_events.
	* xfns.c: #include "xfns.h".
	(Vx_send_movement_events): Define this variable.
	(syms_of_xfns): DEFVAR_LISP it.
	* xterm.c: #include "xfns.h".
	(XTread_socket): Place a mouse-moved event in the buffer iff
	Vx_send_movement_events says to.

1991-01-28  Jim Blandy  (jimb@geech.ai.mit.edu)

	* ymakefile: noted that callint.o depends on mocklisp.h,
	and dired.o on search.h.

	* environ.h: Deleted - its creation in the first place was misguided.
	callproc.h: Removed #include "environ.h", and added declarations
	for environ.h

	* buffer.c (syms_of_buffer): Add more detailed documentation to
	buffer-undo-list.

	* lisp.h (poll_suppress_count): Add external declaration for this here.

1991-01-28  Richard Stallman  (rms@mole.ai.mit.edu)

	* m-sun3-68881.h, m-sun3-fpa.h, m-sun3-soft.h: New files.

1991-01-27  Jim Blandy  (jimb@geech.ai.mit.edu)

	* lisp.h (struct handler): add poll_suppress_count member, so
	we can restore poll_suppress_count when we handle an error.
	* eval.c (struct catchtag): Add it here too, for throws.
	(internal_catch, Fcondition_case, internal_condition_case): Record
	the value of poll_suppress_count here in the handler and catch tag.
	(Fthrow, Fsignal): Restore it here.

1991-01-25  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* xterm.c (x_display_box_cursor): If we're undrawing the cursor by
	redrawing the character underneath it, draw according to that
	line's highlight, instead of assuming it's in the normal GC.

1991-01-25  Richard Stallman  (rms@mole.ai.mit.edu)

	* buffer.h (PTR_CHAR_POS): Value was too small by 1.

1991-01-16  Richard Stallman  (rms@mole.ai.mit.edu)

	* doprnt.c (doprnt): Check for overflow in fmtcpy.

1991-01-16  Jim Blandy  (jimb@churchy.ai.mit.edu)

	* window.c (Fdelete_window): If the deletee gives its space to its
	next sibling, that sibling needs to have its top/left side pulled
	back to where the deletee's is.

1991-01-15  Jim Blandy  (jimb@geech.ai.mit.edu)

	* doc.c (Fsnarf_documentation): handle attaching docstrings to
	bytecode objects too.

	* syntax.h (syntax_spec_code): make external declaration for this
	unsigned char to match the definition in syntax.c.

	* indent.c (compute_motion): added comments describing how it
	can be used.

1991-01-15  Richard Stallman  (rms@mole.ai.mit.edu)

	* process.c (create_process): Use SETUP_SLAVE_PTY if defined.

	* s-usg5-4.h (HAVE_PTYS, HAVE_SETSID): Defined.
	(HAVE_WAIT_HEADER, WAITTYPE, wait3, WRETCODE): New macros.
	(TIOCSIGSEND): Alias for TIOCSIGNAL.
	(FIRST_PTY_LETTER): Overridden.
	(PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF, SETUP_SLAVE_PTY): New macros.

	* m-ibmrs6000.h	(CANNOT_DUMP): Undefine it.
	(UNEXEC): Define it.
	(PURE_SEG_BITS, SHMKEY): Define only if CANNOT_DUMP.

	* xdisp.c (redisplay, display_mode_line): To test
	Vglobal_minibuffer_screen for validity, you must check that its
	type is Lisp_Screen; comparing it to Qnil isn't good enough.

	bug?)

	* dispnew.c (init_display): Make sure that the standard input is a
	terminal here.
	* emacs.c (main): Not here, since we don't know yet if we want to
	use a window system of some sort.

	format to 32 and send only 1 element.  Pass the address of size,
	not size itself.

	containing the size of the transfer.  This generates a
	PropertyNotify to the owner, starting the exchange.

	* xrdb.c (get_user_app): Pass correct number of parameters to
	sprintf.

	* xfns.c (x_window): Don't use backing store or saveunders; they
	seem to slow down suns.

	(x_make_gc): Initialize gc_values.line_width to zero before
	creating the normal video GC, since it uses it.  And set the

	this nonexistent function.

1991-01-04  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* window.c (window_loop): neatened up.  MINI being non-zero now
	makes it recognize active minibuffer windows.  Iterates properly
	over multiple screens when asked nicely.
	(Fget_lru_window, Fget_largest_window): SCREENS arguments are now
	declared as a Lisp_Object, and documented.
	(Fget_buffer_window): SCREENS argument is now documented.

	* undo.c (record_delete): Removed dead variable llength.

	* data.c (Qkeyp, Fkeyp): Removed these and supporting code.

1991-01-03  Richard Stallman  (rms@mole.ai.mit.edu)

	* search.c (search_buffer): Return starting position if count == 0.

1991-01-02  Jim Blandy  (jimb@pogo.ai.mit.edu)

	only define these functions ifdef HAVE_X_WINDOWS.
	(window_from_coordinates): use next_screen_window instead of
	Fnext_window, so that global minibuffers work.

	* lread.c (syms_of_read): Don't forget to defsubr
	read-char-exclusive.

	* lisp.h (Fscreenp, Fselect_screen, Ffocus_screen,

	Flocate_window_from_coordinates, Frubber_band_rectangle): added
	extern declarations for all these.

	* lisp.h (Qscreenp): added an extern declaration for this.

	* lisp.h (DBL_DIG): Added constant for the maximum number of
	decimal digits a float could print to.  Used in print.c.

	mouse and window system events too.
	(Fsingle_key_description): signal an error if obj is not a key.

	* data.c (Fkeyp, Qkeyp): Added predicate to recognize things which
	can be bound - this includes keys, symbols (for function keys and
	window system events), and conses (for mouse events).
	* lisp.h (Qkeyp): Added external declaration for this.

	* keyboard.c (Frecursive_edit): Don't specbind the standard IO here.

1991-01-01  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* fileio.c (Fwrite_region): We should dereference GPT_ADDR[-1]
	before comparing it to '\n' for VMS cruft.

	* eval.c (Fsignal): Don't ever return.
	Call error instead if user tries to use debugger to return.

	* eval.c (unbind_to): New second arg is value to return.  gcpro it.
	All callers changed to pass the arg; if a caller uses unbind_to
	just before returning, it passes as this arg the value it wants
	to return, then it returns whatever comes back.

1990-12-28  Jim Blandy  (jimb@geech.ai.mit.edu)

	* print.c (print): put obj in a non-register variable so
	we could gcpro it.  Also fixed some syntax errors.

	* editfns.c (Fformat): declare nstrings, and declare nstrings and
	strings in a local block.
	(Fformat): XFLOAT(args[n]) isn't a float; ->data is.

	* fileio.c (err_str): New macro.
	(Finsert_file_contents, Fwrite_region): Use it in error messages.

	* Globally rewrote all references to Vmouse_buffer to use the
	buffer viewed by Vmouse_window instead.

	* alloc.c (xmalloc, xrealloc): removed calls to
	{un,}hold_window_change.  The new SIGWINCH-handling code and
	do_pending_window_change make them unnecessary.

1990-11-11  Richard Stallman  (rms@mole.ai.mit.edu)

	change_window_size_1 into a loop which scans list of screens and
	resizes those that need resizing.

1990-11-06  Richard Stallman  (rms@mole.ai.mit.edu)

	* m-ibmrs6000.h (CANNOT_DUMP): Define it.

	* process.c (create_process): Unblock SIGCHLD in the child.

	* process.c (wait_reading_process_input): Don't read input

	* indent.c (position_indentation): renamed stray `bf_cur' to
	`current_buffer', and old `CharAt' usages to `FETCH_CHAR'.
	* buffer.c (Fbuffer_disable_undo): the symbol object for this
	subroutine was still named Sbuffer_flush_undo, and the symbol's
	lisp name was similarly out of date.  Renamed both, and added an
	alias in lisp/subr.el .

	* keyboard.c (Fset_input_mode): a `meta_flag' had escaped being
	renamed to `meta_key'.

1990-10-29  Richard Stallman  (rms@mole.ai.mit.edu)

	* process.c (Fprocess_send_region, Fprocess_send_string):
	Break data into bunches less than 500 bytes.
	Accept process output between bunches.
	??? Must update manual.

1990-10-29  Jim Blandy  (jimb@pogo.ai.mit.edu)

	* window.c (Fset_window_start, window_scroll): renamed stray
	references to `redo_mode_line' to `update_mode_line'.

	included environ.h.

1990-10-24  Jim Blandy  (jimb@pogo.ai.mit.edu)

	extern declarations for these functions, included mocklisp.h.
	Moved external declaration of index to top of file.

1990-10-24  Richard Stallman  (rms@mole.ai.mit.edu)
