--- Comment #3 from Michele Caini <michele.caini at gmail dot com> --- (In reply to Jakub Jelinek from comment #1) > Shall we remove that altogether, or just pedwarn on it? I suspect it should be rejected, unless it is an intended extension of the compiler (for which I've not been able to find the docs - in this case, a pedwarn should be emitted at least).
