  On at least one version of Masscomp's UNIX I've used, index/rindex exist,
as well as strchr/strrchr.  The functions work identically, EXCEPT, that
index/rindex return -1 (cast to a pointer, I suppose), in case of no match,
rather than a null pointer.  Mind, this was some time ago, and I would imagine
it's been fixed by now, but verbum sap.
