If the initialization of type objects is all that needs fixing to
get Python compile to on MinGW32, why not simply fix it ? MSVC has had
the same problem for years. What's strange is that in some cases,
MSVC does seem to get it right where in others it fails with an
error -- probably a DLL vs. EXE thing.
