+  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.
