While this is fine for sparc64, and I think is OK for all architectures
NetBSD supports, it is not correct C; converting to i6addr_t * may lose
information, which of course cannot be recovered by casting back to
some other type.

Why cast to i6addr_t * at all, when IP6_NEQ casts immediately anyway?
