It's not a "system call" in the sense that it calls the kernel, but it is a
routine in the C library.  It actually predates BSD; AT&T changed the name of
this routine from "index" to "strchr" at one point, so "strchr" is the (exact)
equivalent.  (Similarly, "rindex" was renamed to "strrchr".)

I'm somewhat surprised that this occurred; programs as widely distributed and
used "pathalias" often have #ifdefs or some trick such as that to ensure that
"index" and "rindex" get aliased to "strchr" and "strrchr", or vice versa, when
building on systems with the name not used in the code.  You might want to make
sure you're building it correctly....
