This is starting to feel tautological, or self-referential, or
something.  If by ccpython.cc you mean
http://cvs.sourceforge.net/viewcvs.py/*checkout*/python/python/dist/src/Modules/ccpython.cc
well of *course* linking will fail.  You have to compile that file as
C++ program since it uses

    extern "C"

which is only legal in C++ .  But AFAICT, in a normal build of the
Python executable, there's no reason at all for main to be a C++
function in the first place.

Unless, of course, I'm missing something.  So if I am missing
something, what is it?
