Dummy argument names and interface bodies

Ifort complains that the name `node` inside the interface body for `two` isn't a type.  I think it is getting confused by the use of `node` as a dummy argument in the previous interface body.

MODULE m
  IMPLICIT NONE

  TYPE :: Node
  END TYPE Node

  INTERFACE
    MODULE SUBROUTINE one(node)
      INTEGER :: node
    END SUBROUTINE one

    MODULE SUBROUTINE two(arg)
      TYPE(Node) :: arg
    END SUBROUTINE two
  END INTERFACE
END MODULE m
