+Subject: [PATCH] Do not warn for header-hygiene.
+
+QtDeclarative is consciously leaking the namespace QtQml.
+Therefore clang would warn about header hygiene.
+Unfortunately this cannot be fixed in QtDeclarative,
+unless we accept not to be able to use QtQuick1 and QtQuick2
+in the same application.
