I admit I don't even _really_ care that much about allowing the feature. More that it might not be worth trying to crack down on it so aggressively, and just letting it get picked up by review (or if it slips through, letting the poor souls stuck on HP/UX complain). (And I say "worth" because now the use of gcc 4.8 as the checking tool has demonstrably cost a bunch of human time, so it comes with a cost). -Peff
