Visual Studio does not maintain mod16 stack alignment and therefore
any assembly function that relies on it will probably crash.  This
includes the SSE2 deblocking routines and SSE2 avg_weight also.

A patch is in the works to disable these under MSVC, enabling building
x264 on MSVC at the cost of a significant speed hit.  Either way, use
of gcc is highly recommend and use of MSVC highly discouraged.
