gcc 3.3.1 on AIX 5.2?

Anyone running recent a recent gcc release on AIX 5.2? I've tried
building gcc 3.3.1 with a mostly-working IBM compiled gcc, and gnumake.
The error is during the libgcc2 build. I have a vague recollection
building gcc on MacBSD 0.8 where some m68k gcc libraries can't be
natively built by gcc... Is this something similar?

Build error is:
