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.)
