  *  Purpose\n\
  *  =======\n\
  *\n\
  *  IZMAX1 finds the index of the element whose real part has maximum\n\
  *  absolute value.\n\
  *\n\
  *  Based on IZAMAX from Level 1 BLAS.\n\
  *  The change is to use the 'genuine' absolute value.\n\
  *\n\
  *  Contributed by Nick Higham for use with ZLACON.\n\
  *\n\n\
  *  Arguments\n\
  *  =========\n\
  *\n\
  *  N       (input) INTEGER\n\
  *          The number of elements in the vector CX.\n\
  *\n\
  *  CX      (input) COMPLEX*16 array, dimension (N)\n\
  *          The vector whose elements will be summed.\n\
  *\n\
  *  INCX    (input) INTEGER\n\
  *          The spacing between successive values of CX.  INCX >= 1.\n\
