+*  =============
+*>
+*> \verbatim
+*>
+*> SLASCL2 performs a diagonal scaling on a vector:
+*>   x <-- D * x
+*> where the diagonal matrix D is stored as a vector.
+*>
+*> Eventually to be replaced by BLAS_sge_diag_scale in the new BLAS
+*> standard.

+*
+*  Arguments:
+*  ==========
+*
+*> \param[in] M
+*> \verbatim
+*>          M is INTEGER
+*>     The number of rows of D and X. M >= 0.
+*> \endverbatim
+*>
+*> \param[in] N
+*> \verbatim
+*>          N is INTEGER
+*>     The number of columns of D and X. N >= 0.
+*> \endverbatim
+*>
+*> \param[in] D
+*> \verbatim
+*>          D is REAL array, length M
+*>     Diagonal matrix D, stored as a vector of length M.
+*> \endverbatim
+*>
+*> \param[in,out] X
+*> \verbatim
+*>          X is REAL array, dimension (LDX,N)
+*>     On entry, the vector X to be scaled by D.
+*>     On exit, the scaled vector.
+*> \endverbatim
+*>
+*> \param[in] LDX
+*> \verbatim
+*>          LDX is INTEGER
+*>     The leading dimension of the vector X. LDX >= 0.
