We build everything with MSVC 2008, as mixing mingw/MSVC often causes trouble. We do provide mingw so that people can build extensions without depending on MS toolchain, but that's not a setup I would recommend in general. It works well for extensions that don't depend much on the C runtime (numpy is a good example), but as soon as you manipulate IO, etc... you encounter issues linked to ABI incompatibilities between what you get from the python runtime and mingw.
