[Bug fortran/39850] New: Too strict checking for procedures as actual argument

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Issue came up when testing/rewiewing proc pointers, cf.
http://gcc.gnu.org/ml/fortran/2009-04/msg00214.html

The following program is believed to be correct and it runs with g95, NAG f95,
sunf95, openf95, and ifort, but not with gfortran:
  Error: Type/rank mismatch in argument 'a'

real function func()
 func = 42.0
end function func

program test
  external func  ! subroutine or implicitly typed real function
  call sub(func) ! Error: Type/rank mismatch in argument 'a'
contains
  subroutine sub(a)
   real, external :: a
   print *, a(0.4)
  end subroutine sub
end
