To follow up on my own post, I've noticed that Python distutils under Cygwin
does not link to /usr/bin/libpython2.1.dll, but rather
to -L/usr/lib/python2.1/config -lpython2.1, which is a different library.

Anyway, when I try this new approach, the linking stage fails due to extra
leading underscores in object files. Since this is the same problem as in
http://www.cygwin.com/ml/cygwin/2001-07/msg01699.html , I'll append what
I've done and my problems to that thread.
