Firts test with Tatsuro's 3.6.0 and OpenBLAS MultiArch
(number of threads controlled with GOTO_NUM_THREADS)

Threads    Linux 64 bit/ATLAS      Win7 32bit/OpenBLAS
1               19.3                            21.3
2               NA                              11.8
4               8.3                              7.5

dual core atom (HT) all numbers in seconds.
With the example A=randn(n); B=randn(n);tic; C=A*B; t=toc,

This also shows a significant speedup for the multithreading (scales
even better than ATLAS).

I failed so far to install the 3.6.1 (somehow the download files seem to
be corrupt) and to test the other BLAS libs, will try this another day.
