  Using built-in specs.
  Target: x86_64-pc-mingw32

I don't know much about the target platform.

Your subject line talks about mingw-w64, then you have set the target as
mingw32.  Even of the names are not entirely symmetric, presumably they
are intended to be, and refer to a 64-bit and 32-bit Windos ABI,
respectively?

The 32-bit ABI is known to work, but I am not aware of any port of GMP
to any 64-bit Windos ABI.

If mingw-w64/mingw64 is to use the standard x86_64 calling conventions,
then porting should not be terribly difficult.  Porting to Microsoft's
64-bit ABI will be much harder, since they changed anything they could
change, compared to the x86_64 standard calling conventions.
