Thanks for this. I don't have the time to read your notes right now, but I will do so. > One of the hacks I made addresses the linking bug.

They key thing here is that without gcc -lmsvcrt100 foo.c working (i.e., not resulting in linking with msvcrt), building Python extensions will always need hacks to workaround that bug. > It is possible, just not easy.

Install any dependencies (e.g., gmp) where gcc can see them. 3. python setup.py build_ext --compiler=mingw32 bdist_wheel (or whatever setup.py invocation suits you, as long as you set compiler=mingw32).
