This is of course the right answer. I'll just amplify a bit:

`rand' is a LCRNG. `random' is significantly more complicated. I'm no expert
of numerical analysis, and in fact I don't understand `random' at all. (Not
that I've tried very hard :)

The appropriate source files, once you've unpacked the DJLSR package, are:

`rand': src/libc/ansi/stdlib/rand.c
`random': src/libc/compat/stdlib/random.c
