Statement from http://www.netlib.org/lapack/revisions.info.3.1

    ***

The interfaces to primary computational routines are fixed and
will not be changed by minor LAPACK versions (e.g. 3.x).
Primary routines are those prefixed by a precision and matrix
type like SGERFS, CUNMQR, ZHEGV, etc., and these interfaces
will remain the same for all LAPACK version 3 versions.
