Then Emacs > won't need to jump through these hoops on 64-bit Windows systems. It'd still have to jump through the hoops for 32-bit systems --with-wide-int, though. Instead, how about fixing our GMP substitute source code to work for this situation, and fall back on it when GMP proper doesn't handle long long? That should work for both 32-bit --with-wide-int and MinGW64, and won't require us to wait for any action on the part of MSYS2 or the GMP maintainers.
