If you want to compile with Cygwin gcc, you need to install the Cygwin Python
2.1 port. It's available in Cygwin's contrib directory (since a few weeks ago).
Just run the Cygwin setup program again and you should be able to install
Python 2.1 from there.

Yes, the Win32 Python distributions are compiled with Microsoft Visual C++.
