Details:

Hi,

I'm building the default branch on macOS 10.12.3
using maports for dependencies and openblas for
blas/lapack.

The build fails at the linking stage with the error


Undefined symbols for architecture x86_64:   "_cggsvd_"


Looking at openblas sources, it appears that cggsvd is
deprecated and replaced by cggsvd3.

The attached patch solves the build problem for me but fails
at runtime with error:


** On entry to SGGSVD31PrecisionSafe Minimum parameter number 24 had an
illegal value
