wtime_test():
  FORTRAN77 version.
  Test wtime().
 
TEST03
  Time the unvectorized loops:
 
    do i = 1, n
      y(i) =        x(i)  
      y(i) = PI *   x(i) )
      y(i) = sqrt ( x(i) )
      y(i) = exp  ( x(i) )
    end do
 
  Data vectors will be of minimum size         4096
  Data vectors will be of maximum size      4194304
  Number of repetitions of the operation:            5
