Distutils supports cygwin and mingw32 for 6 months or so.

The message you read 
(http://mail.python.org/pipermail/distutils-sig/2000-November/001727.html)
is about compiling the whole python using cygwin.

You have to specify 
--compiler=cygwin for cygwin using cygwin1.dll
or
--compiler=mingw32 for cygwin without using cygwin1.dll (or for mingw32)

What you need is a library libpython20.a which serves as import
library for python20.dll.

If you don't want to create this library for your own you may ask Reuben
Sumner
(see
http://mail.python.org/pipermail/distutils-sig/2000-December/001783.html)
for it.


(Greg, it may be a good idea to put this library on the download page of
distutils or python.)
