I have used mingw64 to compile the generic C versions of both GMP and
MPIR on Windows x64 and it works fine. Mingw64 uses the correct
Windows calling conventions and it can hence work with YASM assembler
code in Windows format.
In prinnciple it could hence use our Windows assembler code but it
would have to be set up to do this and this would require someone to
do it.
