You're compiling it wrong. A simple "cc program.c" builds for me.
Note, however, that h_addr_list isn't a set of strings; it's a set of
actual addresses, in network byte order. You'll need to iterate
through those bytes, printing each one separately (the h_length field
tells you how long they are).
