/usr/ucbinclude/vfork.h causing problems with XEmacs 21.4.11, 12
I get this error when I compile stock 21.4.11 or 12 using cc on
Solaris 9:
aar:/usr/local/src/xemacs-build/xemacs-21.4.12(673)$ cc -V
cc: Forte Developer 7 C 5.4 2002/03/09
usage: cc [ options] files. Use 'cc -flags' for details

This patch makes the problem go away:
------------------
aar:/usr/local/src/xemacs-build/xemacs-21.4.12/src(737)$ gdiff -u sysproc.h.orig

------------------
Is this asking for trouble? I've experienced some occasional
crashes[1] doing this with 21.4.11, but I'm not sure if they're
related.
Now that I'm seeing it again with .12, I thought I'd mention it.
