Python ctypes + Intel compilers interop problem

["Jennings, Jared L CTR USAF AFMC 46 SK/CCI" <jared dot jennings dot ctr at eglin dot af dot mil>]

I failed to compile Python 2.6 using Intel compilers (version 9.1). I
reported the issue to the Python folk: http://bugs.python.org/issue4130
(q.v.). After that I found that the file I was talking about was part of
libffi. So I subscribed to this list and lurked some. Now I'm not sure
who wants to know about the problem.

Does Python get its libffi from sourceware? Does libffi intend to be
compilable using any C compiler? If sourceware's libffi fixes this
interoperability issue, will the fix make it into Python eventually?

I can't get to the machine where I found the issue anymore, so I can't
replicate it; but it appears that __INTEL_COMPILER is defined when using
icc, and icc defines the __m128 type instead of the __int128_t type. I
think the only use of __int128_t is in ffi64.c, in the register_args
struct.
