I reckon this discussion is descending into silly degrees of pedantry...
Four-engined should specifically mean propulsion, so no APUs and auxiliary strap-on rockets shouldn't count. Including the He 177 is purely academic anyway as it would have come dead last given its tendency to throw itself apart in the air owing to overstressing of the airframe in vigorous manoeuvres.
Geez guys, be serious...
