No, but you need it for Scipy. And we have always produced NumPy with
Lapack support on windows.

Because there is no free fortran compiler on windows64, except for
gfortran. Since I am not sure whether it will be possible to use
gfortran/Visual Stsudio together to build NumPy/SciPy, I don't want to
distribute binaries which will be incompatible with each other if we
change from Visual Studio to gcc.
People who really need NumPy on win64 can build it by themselves, or use
any other mean (EPD, unofficial binaries, etc...).
