Use ck_warner() more
Replace trivial uses of if(ckWARN(WARN_FOO)) warner(packWARN(WARN_FOO), ...); with ck_warner(packWARN(WARN_FOO), ...); This does mean that the format string arguments get evaluated even if the warning category isn't enabled, but the most expensive thing I could see was Strerror(), which I woudn't worry about.
