Other UNIX platforms, such as Solaris perhaps, could be impacted.

I haven't tested these changes yet, I could give it a try to test this ...
(this will take some time). 

Let me know if there is interest in testing.

By the way there is one configure issue that I reported with Squeak V5.

In order to run the configure script I have to use the command line:

   configure ac_cv_cflags_warn_all="" 

I think this is a "known" issue with the ax_cflags_warn_all.m4 file.

The ax_cflags_warn_all.m4 could be updated as well,

see:

http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=commit;h=b259e09962a25781f614172831957e5dedb0d7ec

it reads there:

"ax_cflags_warn_all.m4: Rewrite AX_FLAGS_WARN_ALL to use AX_COMPILER_VENDOR

Using AX_COMPILER_VENDOR allows significantly more robust selection of
appropriate compiler flags.  In the old code, for example, the Sun
(Oracle) Compiler Suite would accept Intel's "-warn all" detection, with
rather disastrous results.

All current compiler flags are incorporated into the new code without
modification."

Can you perhaps also try to update the ax_cflags_warn_all.m4 macro
and regenerate the configure ?

David Stes
