feel free to test my Atlas 3.10.0 package source package
http://matzeri.altervista.org/cygwin-1.7/atlas/

also openblas
http://matzeri.altervista.org/cygwin-1.7/openblas/

I guess your CPU is different from mine
Intel(R) Core(TM) i5 CPU M 520
so you will need to rebuild the binaries.
ATLAS will take long time, openBLAS is shorter.

For your Octave testing, I suggest to build versus reference LAPACK/BLAS
and just install the ATLAS / OPENBLAS dlls.

I tweaked those at:
