[Zope-Coders] silly windows request

[Chris McDonough]

I think I've figured this out.  I've checked in changes to the
chrism-install-branch setup.py file that seem to make Windows
installation possible under Python 2.1/2.2/2.3.  I have tested it on
both Windows NT (both under Python 2.2b1 and Python 2.1.3) and UNIX
(only tried under 2.3a, but I suspect it works fine under 2.1.3 as
well).

Essentially, I just use a custom "install" class to ignore any of the
install schemes that distutils things are a good idea.  Instead, we
use a hardcoded scheme that just plops everything into
TARGET_DIR/lib/python.

I also might have made it possible to use the Makefile "nmake
uninstall" and "nmake clean" features on W98, but I've not verified
that they work.

I hope I didn't screw up any line endings in the process. ;-)

Thanks for your help.
