["struct a <---> struct b"] - lampman@heurikon.UUCP (Ray Lampman):
} What is the best way to declare three different structures,
} each containing a pointer to the other two?
} I keep running into a forward referencing error.
} I'm looking for a solution without typedef's, I'll add those later.
} aTdHvAaNnKcSe, Ray.

}                                         - Ray Lampman (lampman@heurikon.UUCP)

Try:
	struct a;
	struct b;
	struct c;
	struct a { struct b *bp; struct c *cp; };
	struct b { struct a *ap; struct c *cp; };
	struct c { struct a *ap; struct b *bp; };
