see also "man rindex" =>
INDEX(3)                   Linux Programmer’s Manual                  INDEX(3)
SYNOPSIS
       char *index(const char *s, int c);
       char *rindex(const char *s, int c);
CONFORMING TO
       4.3BSD; marked as LEGACY in POSIX.1-2001.

rindex is BSD-style and not "linuxish" while Linux borrows from BSD *and* SysV.
As I asked before: POSIX 2001 marks many traditional calls as legacy,
obsolescent or deprecated. Which standard is/will toybox conforming to?
The list "C-Lib, cc C99 and OS-API POSIX.1-2001(SUSv3)" would be a nice
simple requirement list - hopefully simple enough for Rob. ;-)
stop joking - IMHO it does not make any sense using/requesting old
standards like POSIX 1996. Another question would be a Open Group standard
but IMHO UNIX03 is not widely used / recognized. And if embedded systems
are a target then 2004 or 2008 standards would IMHO not fit.
