Most warnings are just warnings. A warning like "implicit cast from pointer to integer" is a red flag (I got bit by this one). I think there are a few others that are always worth taking a look at.
I like your idea of marking warnings. Warnings should be treated like the messages from any static analysis tool. A lot of times they are worth at least looking at but you should be able to mark them as "not a problem" if you think you know better. That way you will always look at new warnings and not end up ignoring all warnings because there are too many that are irrelevant.
