Test case:



module m

private

contains

 subroutine s1

 contains

   subroutine s2

   end subroutine

 end subroutine

end module



program test

contains

  subroutine s3

  end subroutine

end





With -Wunused-function, gfortran currently only warns for s1, but not for s2

and s3. (With 4.7, no warning is thrown at all.)
