ffmpeg | branch: master | Hendrik Leppkes <h.leppkes at gmail.com> | Sun Mar 10 23:03:42 2013 +0100| [d6d369bf1370999896500ae7eb5b9447ab635a3d] | committer: Martin Storsjö

atomic: prefer gcc builtins over win32 atomics, if available.

The mingw win32 atomics appear to be faulty, so they should not be used
if the gcc ones are available.
