I have tested full test on the development branch source (changeset 
14388:b5b49f400f9b) using the latest OpenBLAS (alpha2.5 9dcea60).
(Octave and related dependency was linked with Reference BLAS. The libblas.dll 
is replaced with that generated OpenBLAS.)

The OpenBLAS gives only one additional failure (Test in svds.m) for MinGW build.
