I don't think this is safe. MinGW links with msvcrt.dll whereas the
main Python distribution links with msvcr71.dll (due to Visual C++
2003).  It is not safe to mix and blend different C runtime libraries.
If you are to build a C extension with MinGW, you also need to build
Python against msvcrt.dll, i.e. you have to use a Python built with
MinGW or Visual C++ 6.0. There other option is to make MinGW link
against msvcr71.dll. I don't know if that is feasible.
