Phil's 2 and 3 (returning port unreachable), like his 4 (protocol
unreachable) may not be bugs due to unclear specs, but are certainly not a
good idea.  A future spec for hosts (similar to rfc 1009 for gateways) being
written by a group in the IETF will probably specifiy that ICMP error
messages should not be sent due to IP broadcasts.  ICMP echo requests may
not be prohibited however, since they are not error messages.
