Is it actually legal to distribute scipy linked with MKL? Scipy still
includes GPL code (umfpack), and shipping MKL+GPL code integrated into
a single download is extremely dicey... (this goes also for any
downstream users who might package precompiled numpy/scipy with other

(In either case I think we ought to just bite the bullet and get MinGW
4.x running as a supported option, even if we don't use it for the
official binaries and even if this requires some unaesthetic hacks. I
bet we'd have more windows developers if there was an accessible way
to build on windows...)
