If you just want to silence your warning remove all -W from your CFLAGS and
take your revenge back to your compiler. Introducing bugs to just silent warning
is not gona help any one.

This use a custom implementation of l2ping to ping known device and do
proper action when they go away. I don't recommend to use the auto unlonck,
but it is there if someone need it.
