If this does need to be deprecated (and it's a feature for which I hope someone will step forward to fix or reimplement it, since we know people have used it to find integer overflow bugs in their code, despite its known limitations), it should give a deprecation warning on all compilations using the option, not just be deprecated in documentation. -- Joseph S.
