--- Comment #16 from David Edelsohn <dje at gcc dot gnu.org> ---
Bull Freeware provides GCC 4.8.1 for AIX 6.1.  I do not know why they only
provide GCC 4.6.1 for AIX 7.1.  AIX 5.3 no longer is supported by IBM and newer
features in GCC require object file and OS feature not provided by AIX 5.3.

If a customer continues to run AIX 5.3 because they want the system to remain
stable for some legacy software, I do not understand why installing the latest
release of GCC would be a priority.
