Unless there are some *extremely* broken systems out there (this is
always a possibility), there are no systems on which index() and rindex()
return an int.

index and rindex, wherever present, should be EXACTLY identical to
strchr and strrchr, so that, e.g.,

	#define index strchr
	#define strrchr rindex

should work (if you have both in your C library).
