We might be close to a working scipy wheel - discussion evolving over
at https://github.com/scipy/scipy/issues/7551#issuecomment-314922271

If we do succeed, that would make the lack of a numba wheel for
Windows much more significant.

Does anyone know Continuum's plans in this matter?   Is the numba
wheel recipe open-source?
