[issue12837] Patch for issue #12810 removed a valid check on socket ancillary data

[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

This is now generating a compiler warning under OS X because the older POSIX standard is followed where socklen_t can be unsigned.

Attached is a patch to cast msg_controllen to a size big enough to hold either signed 2**31-1 or unsigned 2**32-1 (i.e., long long) to silence the compiler warning. I would check the patch in myself but test_socket is failing under OS X right now so I can't verify I didn't do something extremely stupid with the cast somehow.
