[Distutils] Re: Help with --with-pydebug installation of NumPy on Windows?

[David Abrahams]

Thanks very much, Thomas! I would have done something like this myself,
but I don't know the distutils internals very well.

I hope you get this into the next release. Does it require any external
stimulation (e.g. setup.py changes), or does it "just work"?
