    * interface.c (count_types_test, generic_correspondence,
    gfc_compare_interfaces): Ignore PASS arguments.
    (check_interface1, compare_parameter): Pass NULL arguments to
    gfc_compare_interfaces.
    * gfortran.h (gfc_compare_interfaces): Modified prototype.
    * expr.c (gfc_check_pointer_assign): Pass NULL arguments to
    gfc_compare_interfaces.
    * resolve.c (resolve_structure_cons): Ditto.
    (check_generic_tbp_ambiguity): Determine PASS arguments and pass them
    to gfc_compare_interfaces.
