FWIW, Apache 2.0.47 won't compile with the AIX 5.1 gcc RPM installed on
AIX 5.2:

/bin/sh /home/trawick/httpd-2.0.47/srclib/apr/libtool --silent
--mode=compile gcc -g -O2 -DHAVE_CONFIG_H -U__STR__ -D_THREAD_SAFE
-D_USE_IRS -I../include -I../include/arch/unix -c apr_snprintf.c &&

This is the typical sort of junk that comes when anybody's gcc header
files aren't prepared for the local system. But I'm surprised this
happened with the RPM because it runs fixincludes at install-time.

I haven't debugged this to see exactly what mismatch there is, so take
this just as a warning that some big packages might not build properly.
