I'm not sure what you mean by a forward referencing error.  Since all
pointers are the same size, the compiler shouldn't care if it doesn't
yet know the object that is being pointed to.  The following program
compiles fine on my machine (a VAX running 4.3BSD) --

struct a {
    struct b *bp;		/* forward reference */
    struct c *cp;		/* ditto */
    int other_stuff;
};

struct b {
    struct a *ap;
    struct c *cp;		/* forward reference */
    int other_stuff;
};

struct c {
    struct a *ap;
    struct b *bp;
    int other_stuff;
};

main ( )
{
}
