        * decl.c (add_hidden_procptr_result): Copy the typespec to the hidden
        result.
        * expr.c (gfc_check_pointer_assign): Enable interface check for
        procedure pointer assignments where the rhs is a function returning a
        procedure pointer.
        * resolve.c (resolve_symbol): If an external procedure with unspecified
        return type can not be implicitly typed, it must be a subroutine.
