Plus, even if ctypes works, the code might be incorrect, because they had been assuming structure layouts and symbolic constants that have just a different definition on some other platform, causing the extension module to crash. Writing portable ctypes modules is really hard - significantly harder than writing portable C code (although writing non-portable ctypes code is apparently easier than writing non-portable C code).
