What do you mean by recompiling ? Using Mingw ? Normally, if you just
recompile your extensions without using special distutils options, you
use the same compiler as the one used by python, which generally
avoids mixing runtimes.

In other words, the problem mainly arises when you need to integrate
libraries which you can not recompile with the compiler used by
python, because the code is not visual-studio compatible, or because
the library is only available in binary form.
