4408 * trans-expr.c (gfc_apply_interface_mapping_to_expr): Return
4409 int result that is non-zero if the expression is the function
4410 result. Only the characteristics of the result expression

4455 recalculated using gfc_get_character_type_len so that the
4456 result is correctly cast for character literals and substrings.
4457 Do not use gfc_typenode_for_spec for the final cast.

4484 (resolve_fntype): Remove special treatment for module
4485 derived type functions.
