Do I understand correctly that you are suggesting removing ATLAS from
the Windows distribution? Wouldn't this make numpy very slow? I know
on RHEL5 I see a very large improvement between the basic BLAS/LAPACK
and ATLAS. Perhaps we should make an alternative Windows binary
available without ATLAS just for those having problems with ATLAS?
