[patch] Replace some _MSC_VER with _WIN32

Hi,
Here is another patch for mingw. It replaces some _MSC_VER with _WIN32 so that code currently compiled only for Visual Studio can also be used for mingw. Looks good?

Regards,

Is _WIN32 defined for 64 bit windows builds? If so, then this is ok, else this will need to change.

gives the following definition. So I think we should be OK using it.

_WIN32: Defined for applications for Win32 and Win64. Always defined.
