Use Windows threads library with mingw

Browse Source 
Instead of Posix threads. This seems to fix time
losses of the gcc compiled version for Windows.
The patch replaces the MSVC specific _MSC_VER flag
with _WIN32 and _WIN64 that are defined both by
MSVC and mingw-gcc.

Workaround found by Jim Ablett.

No functional change.
