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

Hi Travis,

the Anaconda binaries (free packages as well as the non-free addons) link
against Intel MKL - not against ATLAS. Are this binaries really free
redistributable as stated?

The lack of numpy/scipy 64bit windows binaries with opensource blas/lapack
with was one of the main reasons to start with the development of a
dedicated mingw-w64 based compiler toolchain to support OpenBLAS / ATLAS
based binaries on windows.
