--- Comment #6 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- A format attribute for syslog is bug 15338. (A fully general system for extensible format checking is hard, as I think it would be a bad idea for it effectively to turn the internals of the format checking implementation into a public API that needs to remain stable. More specific new features, such as an attribute for syslog or more accurate descriptions of what system printf supports on different systems, are easier.)
