The index() and rindex() functions were marked LEGACY in the 2001 revision of POSIX and were subsequently removed from the 2008 revision. The strchr() and strrchr() functions are part of the C standard. This makes the source code a lot more consistent, as most of these C files also call into other str*() routines. In fact, about a dozen already perform strchr() calls.
