At least with MinGW it works: I've just found a work-around. (Cython is
innocent here.)

The problem appears when an extension compiled with gcc tries to import
(by using Python's __import__) another extension compiled with g++.
Both extensions can be imported from Python individually!

My work-around for now is to compile and link everything with g++.

I will look more into this soon.  Does anyone have an idea why mixing
gcc and g++ has these effects?  It works on other platforms, so the code
is OK.
