ATLAS is also "BLAS-only" (i.e. if you download the ATLAS source
tarball and build, all you will get are ATLAS's tuned implementations
of the Basic Linear Algebra Subroutines, LAPACK must be downloaded
separately). LAPACK routines rely on BLAS, The difference is that I
think ATLAS has support for building an (optimized?) LAPACK. I think
it may also do some auto-tuning of LAPACK compiler flags or something.
I'm afraid I have no clue about building on Windows, sorry. If you get
it working, document your steps so we can put it on the website (I'm
pretty sure the version on the wiki/in SVN now are out of date).
