  Version of daytime_client.cpp is indeed 0.3.8.

 Quite strange that struct sockaddr_storage doesn't have any member
"ss_family", instead address family is represented by "__ss_family".

 socket applications can be compiled with COMPAT_43 defined. This will
make the sockaddr structure BSD 4.3 compatible.
