:Bad news: we can't implement r_rand() via random() algorithm because
:r_rand() keeps its state in extenal unsigned variable (not in big table
:needed for random()). So, I suggest again to use my patch since it _is_
:r_rand() compatible.

Ach, your right. The best we can hope for with rand() is to have
it produce a reasonable pseudo-random sequence.
