/* The use of getprotobyname() is disabled since it isn't thread-safe on
numerous systems. On these getprotobyname_r() should be used instead, but
that exists in at least one 4 arg version and one 5 arg version, and
since the proto number rarely changes anyway we now just use the hard
coded number. The "proper" fix would need a configure check for the
correct function much in the same style the gethostbyname_r versions are
detected. */
