[Moved conversation to mailing list]

Hey, guys

I guess we don't have many Windows developers or users (since there
haven't been any bug reports regarding this build problem so far!).
The scikit should work perfectly well under Windows, but clearly we'll
have to adjust the Cython builder.  Christoph, do you know of a way to
programmatically call Cython, instead of running the executable?

Regards
St?fan

I'll add that in - thanks!

Very much, thank you!
