I don't really understand why this needs to be strongly documented --
it is standard behavior on all systems. The hosts requirements RFC
absolutely requires this behavior, and furthermore, this is the
behavior you would expect from a kernel that had not been compiled
with option GATEWAY (which should probably now be named option ROUTER)

Indeed, I actually think its a significant bug that there is no way to
compile the kernel with support for forwarding of source routed
packets off, which is a significant security hole, too...
