The rogue clone uses the 4.2 bsd pseudo-random-number generator, random().
The old familiar rand() does not suffice, for example:

	for (;;) {
		printf("%d, ", rand() % 4);
	}

will generate:  0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, . . .

This is not good enough, to say the least.  This may cause the rogue
clone to get into an infinite loop when digging a maze as it tries
random directions (an integer between 0 and 3), attempting to locate
a room.  Anyone running this code without the new UNIX random() routine
will have to come up with a replacement for random() that works.
