One of the reasons why I started using /* fallthrough */ is because it kept Coverity happy. If the conversion from /* fallthrough */ to the __fallthrough__ attribute means that we start gethting a lot of Coverity warnings, that would be unfortunate. OTOH, if this is getting standardized, maybe we can get Coverity to understand this attribute? - Ted
