gwin32: Fix detection of MinGW32 vs MinGW-w64

Browse Source 
__MINGW32__ is defined on all MinGW variants including MinGW-w64.
__MINGW64_VERSION_MAJOR is only defined on MinGW-w64.

This difference is important because on MinGW-w64 we must #include
winternl.h because including ntdef.h results in compiler errors
about symbol redefinition, and the header warns that it is deprecated
and may be removed in the future.
