  /* > identify machines with a large exponent range, such as the Crays, and */
  /* > redefine the underflow and overflow limits to be the square roots of */
  /* > the values computed by SLAMCH. This subroutine is needed because */
  /* > SLAMCH does not compensate for poor arithmetic in the upper half of */
