</div></div>Can you put this in a more specific warning group, and make it<br>
DefaultError?  Since only very new gcc versions accept this, we really<br>
want to discourage anyone from using it.</blockquote><div> </div><div>Sure thing. Do you want it in a subgroup of -Wgnu, or do you want for -Wno-gnu to leave this enabled?</div></div>
