It does work, but features may be missing.

I don't think there are, because ATLAS is usually statically linked.  But,
I'm the wrong person to ask.

I think so.  Can somebody with windows experience comment here?

I set build_sparse=1 (currently it is set to 0),  in the main setup.py
file and then it goes off and uses the setup_sparse.py file.  I've never
actually tried to install it using just setup_sparse.py though it should probably work.
