You can find these original utilities at

You are braver than I. When I look at my old code, I tend to almost cringe myself to death. XD

The strcasecmp() function is a SUSv4 function but not an ANSI C function.

At 12:50, you didn't need to specify int as it was the default return type of c functions... Pure heresy but today's standards! :D
