You do have a point that it can be bad, but what if when you try to use RAND_MAX, your
compiler gives you a really hard time?? Don't remember exactly what happened when I
tried it, it was a while back. I was trying to seed a randgen that needs 3 seeds. The
easiest way was to seed the regular randgen, and then take the first 3 numbers. I
eventually had to use the mod method, because nothing else could be made to work.
