Yes, these warnings "if you care about internationalization" produce many false alarms, both in Gnulib itself and in application code. The reason is that for _some_ arguments of, say, strchr, there is no problem, whereas for other sets of arguments there is a problem. Any ideas (maybe using some tools from the clang ecosystem?) for reducing the false alarms? Just introducing several classes of warnings would not solve the problem, IMO, since no GNU package is supposed to malfunction in some locales. Bruno
