I often read on the mailing list people saying "who cares about W=2 builds anyway?". At least I do. Not that I want to fix all of them, but on some occasions, such as new driver submissions, I have often found a couple valid diagnostics in the W=2 output.
That said, the annoying thing is that W=2 is heavily polluted by one warning: -Wtype-limits. Try a gcc W=2 build on any file and see the results for yourself. I suspect this to be the reason why so few people are using W=2. This series removes gcc's -Wtype-limits in an attempt to make W=2 more useful. Those who do not use W=2 can continue to not use it if they want. Those who, like me, use it form time to time will get an improved experience from the reduced spam. Extra details on statistics, past attempts and -Wtype-limits alternatives are given in the first patch description.
