Of course!

In my particular case, I have installed stock Python 2.6 (using the
MSI installed from python.org), and I routinely test mpi4py building
it with MSVC Express 2008 and MinGW32, with a couple of different MPI
implementations (DeinoMPI, MPICH2, and very recently Microsoft MPI).
Up to now, all work just fine. Of course, I've been very careful and
my code does not call anything from the C stdlib (which is know to
have issues when building with MinGW, because of possible mismatches
of the C runtime).

OTOH, most of the Cython testsuite pass happily with the stock Python
2.6 and MinGW32. The only offending part are test like 'cdef extern
void foo()', as that end-up with linker errors.
