Yes, of course. But it is useful to be able to use a 32 bits toolchain
to produce 64 bits software.

Not being ABI compatible with Python from python.org is not an option,
and building it with mingw would make it ABI incompatible for sure. I
certainly wished they used an open source compiler to build the official
python binary, but that's not the case.
