AIX 4.3.2 with native IBM compiler xlc 3.6.4 passes all regression tests.
Other versions of OS and compiler should also work. If you don't have 
a powerpc there might be differences in the geometry regression test.

Use the following configure flags in addition to your own:
./configure --without-CXX
and if you have readline there:
--with-includes=/usr/local/include --with-libraries=/usr/local/lib

libpq++ does not work because xlC does not have the string and bool classes.
compiling the few files, that fail, with g++ does work.

Compiling PostgreSQL with gcc (2.95.2) on AIX does work if you use the
configure option: --with-template=aix_gcc 

With the current compiler flags the redefines of int8 - int64, that prior
versions had a problem with, are not a problem any more.
