What I can tell is that is appeared to be working (although distutils is/was broken: http://bugs.python.org/msg67039).
I read that optimally CPython would have to be also compiled with Mingw (although I am not certain it is possible), but I tried and it went OK. On the other hand compiling R with MSVC is (was ?) not possible. Also, I am reading that Mingw - MSVC are playing along better with recent versions http://developer.berlios.de/devlog/akruis/2012/06/10/msvcr90dll-and-mingw/ (the post is hinting has cross-compiling - if this could be worked out for rpy2 it would mean that I could follow-up more closely that it builds for MSWindows).
