What is strdup() supposed to do? Does anyone have a copy?

I think Lars might have jumped the gun a bit here.  Maybe, just MAYBE, Jeff
mis-read Daniel's rewrite as

    sizeof(char) * strlen(foo) + 1

instead of (the correct)

    sizeof(char) * (strlen(foo) + 1)

If this were the case, his comment makes perfect sense.  Regardless, I'm
giving Jeff the benefit of the doubt and blaming his eye doctor! :^)
