Python 2.7.2 on AIX 6.1: Unable to compile with ctypes

[eroussel]

Hello,

I'm trying to figure out the recipe to compile Python 2.7.2 on AIX 6.1
with the ctypes module. I'm using the xlc_r compiler V9.0.

I am currently able to generate an interpreter that works, but lacks
the ctypes module because of compilation errors. From looking at the
newgroup posts and bugs.python.org, there seems to be an issue with
Python, libffi and AIX.

Is the ctypes modules simply unsupported on AIX?

These are the compilation error messages I get:
