Re: AIX compile problems

[Paul Eggert]

Thanks for your bug report.  Unfortunately I don't have an AIX host to
use, so I'll have to ask for your help in fixing things.

One thing you might try is the latest Bison test release, to see
whether the AIX porting bugs are fixed there already: that might save
you some time.  <ftp://alpha.gnu.org/gnu/bison/bison-1.875d.tar.gz>

Can you please explain why this change was needed?  For example, what
error message did you get when you did not have this change installed?
(We'd prefer to have Bison work with the standard AIX headers.)

Can you please explain why these changes were needed too?  For
example, the first file that muscle_tab.c includes is "system.h", and
"system.h" includes <stdlib.h> near the top (after <limits.h>,
<stddef.h>, and <stdio.h>).  So why does it help to include <stdlib.h>
before "system.h"?  Does AIX 5.1 have a bug that requires you to
include stdlib.h before some other system header?
