        * trans-intrinsic.c (gfc_conv_intrinsic_transfer): Ditto.
        * decl.c (do_warn_intrinsic_shadow): Ditto. Renamed from
        warn_intrinsic_shadow.
        * frontend-passes.c (do_warn_function_elimination): Honor
        changed variable names. Renamed from do_warn_function_elimination.
        * invoke.texi (Wunderflow): Document that it is enabled by
        * default.
        * lang.opt (Waliasing, Walign-commons, Warray-temporaries,
