In DJGPP (and other ANSI systems), the function to seed the random number
generator is `srand'. I think this was inadvertently omitted from the
documentation in DJGPP 2.01, but what it does is to seed the RNG with its
argument. If you want actual random numbers, you need to use some value that
changes; `time(NULL)' is a good bet.

If you want to use `random' instead (a better RNG, but a less portable
interface), the corresponding function is `srandom'.
