[Distutils] Compiling Python C++ extensions with MingW

[Andrew Gregory]

Thanks for the reply. 

I had not realised that distutils does not support Mingw when compiling
C++

I searched for "gxx_personality" in files (using find). It's in
libstdc++.a and libsubc++.a which are in the directory C:\MinGW\bin

As soon as I've got time I'll have another go, but linking to these
files.
