*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> CLARSCL2 performs a reciprocal diagonal scaling on an vector:
*>   x <-- inv(D) * x
*> where the REAL diagonal matrix D is stored as a vector.
*>
*> Eventually to be replaced by BLAS_cge_diag_scale in the new BLAS
*> standard.
*> \endverbatim
*
*  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 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 COMPLEX 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 >= M.
