The only two uses in coreutils are in who.c and pinky.c, so that wouldn't cause much trouble. But if some library code uses canon_host, such a change wouldn't go down as well. I suppose the question is whether any library-like code (that would not welcome the output to stderr) uses canon_host. Personally, I don't mind if you add the code to emit warnings now, as long as you agree to adjust the API later, (e.g., to add a new enum parameter describing the error) if anyone complains. Of course, it'd be better to keep it library-safe. _______________________________________________ bug-gnulib mailing list bug-gnulib@gnu.org http://lists.gnu.org/mailman/listinfo/bug-gnulib
