I'm pretty sure it doesn't cross compile to native Windows. It certainly
won't build against a native Windows Python installation, and given the
overhead that cygwin induces into a lot of common OS operations (such as
fork(), I/O operations or file system access), a native Windows Python
installation has serious advantages in most cases.

If the choice is GCC, then MinGW is the right tool.
