While we're at it, Clang in nearing a stage where it can compile C and C++ on Windows with ABI-compatibility to MSVC (yes, even C++) -- see http://clang.llvm.org/docs/MSVCCompatibility.html</a> for more details. Could this help?

Possibly. "cl-clang" is exciting and I hope distutils will support it one day. Clang is not well known among Windows users as it is among users of "Unix" (Apple, Linux, FreeBSD, et al.) It would be even better if Python were bundled with Clang on Windows.

The MinGW-based "SciPy toolchain" has ABI compatibility with MSVC only for C (and Fortran), not C++. Differences from vanilla MinGW is mainly static linkage of the MinGW runtime, different stack alignment (4 bytes instead of 16), and it links with msvcr91.dll instead of msvcrt.dll.
