It was discussed to do:
W=1 - the most usefull warnings
W=2 - the less usefull warnings
W=3 - the noise

Or somthing like that.
But no-one stepped up doing the classification then.
Should be simple to do.

My gcc (4.3.2) barfed over -Wno-unused-but-set-variable.
So your patch needs to check if the option is supported.
