Of course index and rindex are the OLD names and they should probably be
changed throughout the source anyway.  See the excerpt from 'man string'
below...

Actually, the easiest way to do this would be with preprocessor defines:

#define index   strchr
#define rindex  strrchr

Assuming, of course, that the words index and rindex don't occur anywhere
in the source other than in function calls which might be difficult, so
maybe the functions would still be better... :(

Here's the excerpt from 'man string':
...
 SYNOPSIS
      #include <string.h>
      #include <strings.h>
...
    Remarks:
      All functions except index() and rindex() are declared in both headers,
      so only one of the two headers needs to be included.

      The functions index() and rindex() are declared only in <strings.h>,
      and <strings.h>.  They are provided solely for portability of BSD
      applications, and are not recommended for new applications where
      portability is important.  For portable applications, use <string.h>,
      strchr(), and strrchr() instead.
