--- Comment #9 from Harald Anlauf <anlauf at gmx dot de> 2012-12-23 21:54:54 UTC ---
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
