Are there more specific requests than "enable -Wall by default"? Are there requests to remove some options from -Wall? Are there requests to add some options to -Wall? Note that some of the above depend on optimization flag settings (and optimization happening). Those are not good candidates - I think good candidates are those that would still be fully operational with -fsyntax-only. Richard.
