Distutils uses the name python20_bcpp.lib for mypylib.lib (See also
the explanation at the end of this mail.)

Distutils can be used with the free Borland compiler too.
(I have tried it with PyOpenGL 1.5.5 and one of my packages,
but it surely needs more testing.)
What is to do?
First convert all MSVC++ libraries you need from COFF to OMF.
coff2omf python20.lib python20_bcpp.lib
The suffix _bcpp is important if you don't want replace to
original files (python20.lib,...)
When you want to link against a library (python20), distutils checks
if there is a library with _bcpp suffix and uses it, otherwise
it tries the normal name for the library (python20.lib).
The second point is, you have to specify that you want to use the
python setup.py install build_ext --compiler=bcpp
This is all.
