Build failure on macosx -- possibly gcc bug?

Build failure on macosx -- possibly gcc bug?

[Harald Hanche-Olsen]

This is the result of make bootstrap after configure --with-ns
(after a git pull):

gcc -c  -Demacs -DHAVE_CONFIG_H  -I. -I/local/src/emacs/emacs-git/src -I/usr/X11/include -Dtemacs  -I/opt/local/include/librsvg-2 -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include -I/opt/local/include -I/opt/local/include/gtk-2.0 -I/opt/local/include/cairo -I/opt/local/include/pixman-1 -I/opt/local/include/freetype2 -I/opt/local/include/libpng12 -I/opt/local/include/dbus-1.0 -I/opt/local/lib/dbus-1.0/include -g -O2 -Wno-pointer-sign   image.c
In file included from image.c:42:
lisp.h:1854: error: syntax error before ‘jmp_buf’
lisp.h:1854: warning: no semicolon at end of struct or union

Apparently, image.c needs to #include <setjmp.h> before "lisp.h", which
it doesn't. Inserting such a line near the top of src/image.c seems to
have fixed the problem.

Um, forget about the "-- possibly gcc bug?" part of the subject.
I put that there because the poor quality of the gcc error message had
me looking for the problem in the wrong place, and I thought indeed it
was a gcc bug. I discovered my mistake before posting, but forgot to
add the subject line.

This should be fixed now.
