-Wall is for warnings with a great usefulness vs. amount of false positives tradeoff. -W is for those warnings that are still quite useful, but where the tradeoff tilts more the other way, "warnings that are more noisy". It is a judgment call no matter what, none of the attributes here can really be measured (or even defined). Most of the time it is pretty clear though. You'll need to try it out on a pretty big (and varied) corpus of code before you can really be sure, of course. In the end you'll need to make a decision whilst you have only partial data. If it turns out you balanced not so super well, you can always correct that later ;-) Segher
