Problem in client_find() in CVS head

[Nicolas Baradakis]

I get errors "Ignoring request from unknown client ..." when using the
CVS head version. I think there is a problem in the IPv4 addresses
comparison in client_find().

The following patch solved the problem for me, but perhaps there is a
better solution. If I get approval, I can commit it to the CVS.
