  *
  * A novel approach was used here to keep the look and feel of the
  * FORTRAN version.  Altering the FORTRAN-based array indices,
  * starting at element 1, to start at element 0 for C, would require
  * numerous changes, including decrementing the variable indices by 1.
  * Instead, the array E1[] was declared 1 element larger in C.  This
  * allows the FORTRAN index range to function without any literal or
  * variable indices changes.  The array element E1[0] is simply never
  * used and does not alter the benchmark results.
  *
  * The major FORTRAN comment blocks were retained to minimize
  * differences between versions.  Modules N5 and N12, like in the
  * FORTRAN version, have been eliminated here.
  *
  * An optional command-line argument has been provided [-c] to
  * offer continuous repetition of the entire benchmark.
  * An optional argument for setting an alternate LOOP count is also
  * provided.  Define PRINTOUT to cause the POUT() function to print
  * outputs at various stages.  Final timing measurements should be
  * made with the PRINTOUT undefined.
