They were marked LEGACY in POSIX.1-2001, and removed altogether in POSIX.1-2008, with a recommendation to use strchr(3) and strrchr(3) instead. So systems that zealously follow the POSIX spec may not have those functions any longer, which is probably what you've encountered. Just out of curiosity, what system shows the problem?
