+ Put back the old socket code; if on a machine that does not properly
+ support the getaddrinfo API, then use it. This is probably much
+ simpler than reimplementing it. This might get us working again on
+ RedHat 5 and similar systems. Although the Kame patch seems like a
+ good idea, in fact it is a much broader interface than the
+ relatively narrow "open by name", "accept and log" interface that
+ rsync uses internally, and it has the disadvantage of clashing with
+ half-arsed implementations of the API.
