Problem Building Emacs

[Alan McConnell <alan@patriot.net>]

I have had similar problems in building GNU/Emacs in two different
versions:

emacs 19.34(source downloaded from ftp.gnu.org):  I can run ./configure
without a problem.  When I then type "make" the compile quickly exits
with a complaint about /usr/include/unistd.h: at line 568 "parse error
before '('", "parse error before __pgrp" and then,
at emacs.c 657 "too few arguments to function get pgrp"

emacs 20.6(source downloaded from ftp.gnu.org):  I can run ./configure
without a problem.  When I then type "make" the complie quickly exits
with a complaint about /usr/include/unistd.h: at line 562, "macro 'setpgrp'
requires 2 arguments, but only one given."

Needless to say, I am anxious about my /usr/include/unistd.h.  I am running
Mandrake 8.2, and maybe they have given me a corrupt unistd.h?  But I had
a friend send me his unistd.h, and "diff" on them reveals no difference.

As mentioned, I am running Mandrake 8.2, with gcc 2.96.  I give you, just
below, lines 547 to 576 of my /usr/include/unistd.h.

The tips about submitting bugs tell us that we shouldn't speculate about
the cause of difficulties, and so I won't.

I shall be very grateful to you for any help that you can give with this
problem.

Best wishes,

Alan McConnell

#if defined __USE_SVID || defined __USE_BSD || defined __USE_XOPEN_EXTENDED
/* Both System V and BSD have `setpgrp' functions, but with different
   calling conventions.  The BSD function is the same as POSIX.1 `setpgid'
   (above).  The System V function takes no arguments and puts the calling
   process in its on group like `setpgid (0, 0)'.

   New programs should always use `setpgid' instead.

   The default in GNU is to provide the System V function.  The BSD
   function is available under -D_BSD_SOURCE.  */

/* Set the process group ID of the calling process to its own PID.
   This is exactly the same as `setpgid (0, 0)'.  */
