[PATCH] socklen_t needs to be defined and libssl to be linked on old Mac OS X

On older Mac OS X (10.2.8), no socklen_t is defined, and therefore
daemon.c does not compile. However, Mac OS X 10.4 seems to define
socklen_t differently.

Also, linking fails due to some symbols defined in libssl (not just
libcrypto).

[jc: I am tentatively dropping the socklen_t part of the patch
because I am waiting for confirmation on the server side IPV6
patch from Yoshifuji-san]
