[Numpy-discussion] Copyright status of NumPy binaries on Windows/OS X

Only on Windows does free Anaconda link against the MKL. But, you are
correct, that the MKL-linked binaries can only be re-distributed if the
person or entity doing the re-distribution has a valid MKL license from
Microsoft has actually released their Visual Studio 2008 compiler stack so
that OpenBLAS and ATLAS could be compiled on Windows for these platforms as
well. I would be very interested to see conda packages for these
libraries which should be pretty straightforward to build.
