Compiling Emacs 19.26 with GCC 2.6.0 on a Sparc 10/41 running Solaris 5.3.

s/sol2.h says to use -traditional to ``work around bugs in system header
files''.  But this results in an error compiling src/gmalloc.c:

gcc -V 2.6.0 -c  -Demacs -DHAVE_CONFIG_H  -I. -I/usr/eng/gnu/src/emacs-19.26/src   -traditional    -I/usr/local/x11r5/include      -g -O2 -DPURESIZE=450000 gmalloc.c
gmalloc.c:1250: parse error before `ptrdiff_t'

I suspect the -traditional is left over from the days of GCC 1.

I took out the -traditional, reconfigured, recompiled, and everything
went fine except sysdep.c: HAVE_VFORK needs to be defined; the
definition in sysdep.c conflicts with the declaration in unistd.h.
Probably configure.in should call AC_VFORK (AC_FUNC_VFORK in the new
Autoconf).

(Well, without -traditional there are warnings about <string.h>
declarations conflicting with built-in prototypes, but that's a GCC bug,
I think.  And they're just warnings.)


Also on the subject of s/sol2.h: it says

(For that matter, you can also take out my apparently-broken code in
src/fileio.c that is enabled if SOLARIS_BROKEN_ACCESS is defined, since
nothing defines it.)
