In case someone tries to do:
if (foo)
CLUTTER_NOTE(DOMAIN, "%s", blah);
CLUTTER_NOTE () should always be a statement
#else /* !CLUTTER_ENABLE_DEBUG */
-#define CLUTTER_NOTE(type,...)
-#define CLUTTER_MARK()
-#define CLUTTER_DBG(x)
-#define CLUTTER_GLERR()
-#define CLUTTER_TIMESTAMP(type,...)
+#define CLUTTER_NOTE(type,...) G_STMT_START { } G_STMT_END
+#define CLUTTER_MARK() G_STMT_START { } G_STMT_END

+#define CLUTTER_GLERR() G_STMT_START { } G_STMT_END

#endif /* CLUTTER_ENABLE_DEBUG */
