--- Comment #8 from David Edelsohn <dje at gcc dot gnu.org> ---
Patches are reviewed on gcc-patches mailinglist, not in Bugzilla
> The attached patch is everything I've got so far to address issues in
> building GCC on AIX 4.3. This covers issues beyond this bug report, but I
> figured you'd rather take care of everything in one go. A walk-through of
> the changes:
>
> ++ gcc/opt-functions.awk
>
> * Escape "{" characters to not annoy older awk programs
Prerequisites for GCC explicitly states that POSIX or SVR4 awk is required, so
I don't think that this work-around would be accepted. For example, you can
install GNU Awk.

This already has been changed.
> * ASM_WEAKEN_DECL() was coming up undefined, too, even though the call is in

The fixincludes changes are the most plausible ones.
