        * resolve.c (resolve_function): Add name after test for pureness.

        * iresolve.c (gfc_resolve_dot_product):  Remove any difference in
        treatment of logical types.

        must be referenced to include unreferenced symbols in an interface
        body.

        functions. (gfc_free_namespace): Call them.

        gfc_equiv_list and gfc_equiv_info.

        PR fortran/25395
        * trans-common.c (add_equivalences): Add a new flag that is set when
        an equivalence is seen that prevents more from being reset until the
        start of a new traversal of the list, thus ensuring completion of
        all the equivalences.

        (resolve_fl_variable): Remove code for the new function and call it.

        with non-constant shape, using is_non_constant_shape_array.

        * trans-expr.c (gfc_add_interface_mapping): Use the actual argument
        for character(*) arrays, rather than casting to the type and kind
        parameters of the formal argument.
