Please, Carl correct me if I'm wrong, but I think the main issues are:

1) Linking to the right MSVC runtime for each Python version (seems to
need different gcc specs)
2) Static linking - Carl's toolchain does full static linking
including C runtimes so we don't need to deal with the DLL path.  I'm
not sure what the ruby devkit does to solve that.

It looks like they have their own Mingw-w64 toolchain.
