+Cody made this look more like the original entry by restoring the `#define` of
+`define`. It's not used but it now looks closer to the original.
+
+Also because `index(3)` is deprecated and in some systems requires the inclusion
+of `strings.h` and because it's identical in use to `strchr(3)` (and we noted
+that for System V we had to do this) Cody added to the Makefile

 Cody made this safer by using `fgets()` instead of `gets()`. This prevents an
