[x264-devel] Native win32 threads

[Gianluigi Tiesi]

This patch make use of win32 native threads without support
of pthreads, Tested with mingw32, I've problem compiling x264 with msvc6 for it but I
don't care since I need mingw32 version, but it shouldn't be a problem
with msvc since the patch is very simple.
Bye
