@koobs: I was just looking at the 3.2.1 code where it still looks like ffi_call_win32() gets called even on non-Win32 platforms.

That said, it's possible that ffi_call_win32() is indeed defined on other platforms than Win32 as well in 3.2.1 - after all, it just implements a particular calling method. I haven't checked that or actually tried compiling _ctypes with 3.2.1.

Perhaps we could try switch to 3.2.1 and then check the buildbots for possible issues ?!
