The gods weren't listening, or didn't care to answer.

Given the complete lack of interest shown in this subject by the general
Python community, I'll drop it. In case anyone is interested I now think
that on balance the following is the best way to get Python extension
modules to build on for Cygwin Python:

As Jason Tishler has pointed out, this has the advantage of working with the
traditional Makefile.pre method as well as the distutils.
