  *  Purpose\n\
  *  =======\n\
  *\n\
  *  CUNMR2 overwrites the general complex m-by-n matrix C with\n\
  *\n\
  *        Q * C  if SIDE = 'L' and TRANS = 'N', or\n\
  *\n\
  *        Q'* C  if SIDE = 'L' and TRANS = 'C', or\n\
  *\n\
  *        C * Q  if SIDE = 'R' and TRANS = 'N', or\n\
  *\n\
  *        C * Q' if SIDE = 'R' and TRANS = 'C',\n\
  *\n\
  *  where Q is a complex unitary matrix defined as the product of k\n\
  *  elementary reflectors\n\
  *\n\
  *        Q = H(1)' H(2)' . . . H(k)'\n\
  *\n\
  *  as returned by CGERQF. Q is of order m if SIDE = 'L' and of order n\n\
  *  if SIDE = 'R'.\n\
  *\n\n\
  *  Arguments\n\
  *  =========\n\
  *\n\
  *  SIDE    (input) CHARACTER*1\n\
  *          = 'L': apply Q or Q' from the Left\n\
  *          = 'R': apply Q or Q' from the Right\n\
  *\n\
  *  TRANS   (input) CHARACTER*1\n\
  *          = 'N': apply Q  (No transpose)\n\
  *          = 'C': apply Q' (Conjugate transpose)\n\
  *\n\
  *  M       (input) INTEGER\n\
  *          The number of rows of the matrix C. M >= 0.\n\
  *\n\
  *  N       (input) INTEGER\n\
  *          The number of columns of the matrix C. N >= 0.\n\
  *\n\
  *  K       (input) INTEGER\n\
  *          The number of elementary reflectors whose product defines\n\
  *          the matrix Q.\n\
  *          If SIDE = 'L', M >= K >= 0;\n\

  *                               (LDA,N) if SIDE = 'R'\n\
  *          The i-th row must contain the vector which defines the\n\
  *          elementary reflector H(i), for i = 1,2,...,k, as returned by\n\
  *          CGERQF in the last k rows of its array argument A.\n\
  *          A is modified by the routine but restored on exit.\n\
  *\n\
  *  LDA     (input) INTEGER\n\
  *          The leading dimension of the array A. LDA >= max(1,K).\n\
  *\n\
  *  TAU     (input) COMPLEX array, dimension (K)\n\
  *          TAU(i) must contain the scalar factor of the elementary\n\
  *          reflector H(i), as returned by CGERQF.\n\
  *\n\
  *  C       (input/output) COMPLEX array, dimension (LDC,N)\n\
  *          On entry, the m-by-n matrix C.\n\
  *          On exit, C is overwritten by Q*C or Q'*C or C*Q' or C*Q.\n\
  *\n\
  *  LDC     (input) INTEGER\n\
  *          The leading dimension of the array C. LDC >= max(1,M).\n\
