--- Comment #7 from uecker at gcc dot gnu.org --- Created attachment 59568 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59568&action=edit patch for pre-C23 Use C23 TYPE_CANONICAL logic also for earlier language modes. There a couple of checking errors (which I think all related to known bugs)
