ENABLE_DASHBOARD_SUPPORT does not need to be a FEATURE_DEFINE I made i one as part of various Platform.h cleanup in: http://trac.webkit.org/changeset/36074 Mark fixed it to actually work in: http://trac.webkit.org/changeset/36076 http://trac.webkit.org/changeset/36078 It doesn't need to be a FEATURE_DEFINE, since it only works for Mac. it can still be a separate ifdef though, but Platform.h can just turn it on for Apple-Mac only (once we have a way to distinguish Apple's Mac port from any other Mac port).
After r36074 we have ENABLE_DASHBOARD_SUPPORT sprinkled over many files. It's not a "feature" like the other items listed in FEATURE_DEFINES, so it should be removed from there ASAP.
Fixed in r36102.
