gcc compiler on AIX 5.2

Does anybody know a web site where I could download gcc for AIX 5.2 (I've downloaded gcc 3.2 from http://www.bullfreeware.com/, but it doesn't work)?
Thanks a lot for your answers.

Give this a try http://aixpdslib.seas.ucla.edu

I downloaded gcc 3.3.2.0 from the Bull site a couple of days ago from the 5.2 section and that seemed fine.
