*  Purpose
*  =======
*
*  CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A.
*
*  Note that while it is possible to overflow while converting
*  from double to single, it is not possible to overflow when
*  converting from single to double.
*
*  This is an auxiliary routine so there is no argument checking.
*
*  Arguments
*  =========
*
*  M       (input) INTEGER
*          The number of lines of the matrix A.  M >= 0.
*
*  N       (input) INTEGER
*          The number of columns of the matrix A.  N >= 0.
*
*  SA      (input) COMPLEX array, dimension (LDSA,N)
*          On entry, the M-by-N coefficient matrix SA.
*
*  LDSA    (input) INTEGER
*          The leading dimension of the array SA.  LDSA >= max(1,M).
*
*  A       (output) COMPLEX*16 array, dimension (LDA,N)
*          On exit, the M-by-N coefficient matrix A.
*
*  LDA     (input) INTEGER
*          The leading dimension of the array A.  LDA >= max(1,M).
*
*  INFO    (output) INTEGER
*          = 0:  successful exit
