I reported this to the webkit-gtk mailing list and Michael Catanzaro said they were probably ok, but either the warning should be disabled or suppressed for these files, see https://lists.webkit.org/archives/list/webkit-gtk@lists.webkit.org/message/2GUR4GPWCV3XIBHWLT6L3JAED5AT6X23/ and to report a bug.
