I would hope not, stacking multiple case values together is a common technique that almost never indicates a coding accident. The fall- through warning should only get triggered when there is executable code without a break between the various case values. Good: case 1: case 2: code(); break; Warning: case 1: code(); case 2: morecode(); break; -- Ian _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
