Ian Dowse c8bb99e577 Certain ICMP error replies cause ping to perform a reverse DNS ... lookup on an IP address from the packet (such as the IP that sent a TTL exceeded error). If the DNS lookup takes a long time, ^C will appear to be ineffective since the SIGINT handler just sets a flag and returns. Work around this by exiting immediately on receipt of a second SIGINT when DNS lookups are enabled. PR: bin/4696 MFC after: 1 week		2004-02-08 21:59:17 +00:00
