This is a different project then mingw, although they both sound the same
and as far as I understand it, run by different team. Mingw-w64 does both
32-bit and 64-bit, while mingw from http://mingw.org only does 32-bit, at
this time.

There were no changes to my build environment to go from mingw to mingw-w64,
except for changing the windows "path" from c:\mingw to c:\mingw64 when
executing my build script.

The GCC and 'binutils' is what allows cross-compiling. So as long as the
toolchain provides the 32-bit and 64-bit version of 'binutils', you can
cross-compile it. Mingw only provide 32-bit for now, that is why I had to
switch to mingw-w64 to compile my code.
