Subject: [PATCH] Remove workaround for AIX 3.2 crashes

Emacs does not support AIX 3.2 since 2008.

This workaround for AIX 3.2.3 and 3.2.4 (released in 1992) was added in
1999, and was only active with '#ifdef AIX3_2'.  In 2008, this condition
was changed to '#ifdef AIX', when support for these ancient versions of
AIX was removed.  I couldn't find any justification for why this was
kept (rather than removed) in the commit message or in the mailing list
archives.

Given that users of versions of AIX 4.0 (released in 1995) or later did
not have this workaround for a decade (1999-2008), I think it's safe to
assume that it's dead wood that is not needed now either.  Note that
this will also avoid incorrectly overriding the LANG variable on that
system.

* src/emacs.c [AIX] (main): Remove workaround for AIX 3.2.
