64-bit MinGW-w64 GCC defines __MINGW32__ already so that change isn't relevant and should therefore not be done (minimum change/patch-size principle). To see the predefined flags you can use:

echo "" | gcc -E -dM -

I explicitly won't merge fixes for searching outside of MSYS2. GPGME upstream may be interested in your patch for that though.

If you do the PATH search that would be fine though!
