Some more cases where a warning is desired

or the current behavior is inconsistent:



  real(8) :: a = 0.1_8

  real(4) :: b = 0.2

  print *, 0.1_8 ** 0.2            ! No Warning

  print *, exp (0.2 * log (0.1_8)) ! No Warning

  print *,     a ** b              ! No Warning

  print *, exp (b   * log (a))     ! Warning

end
