[Bug-gnulib] obstack.h port to IRIX 6.5 (native c89)

I installed the following gnulib patch to merge changes from Bison.
Hmm, I suppose someone needs to merge glibc obstack.h with gnulib
obstack.h at some point?  I'm not quite sure of the relationship here.

        * obstack.h: (__INT_TO_PTR) [__STDC__]: Cast result to
        (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
        when compiling Bison 1.875's `bitset bset = obstack_alloc
        (bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.
