commit 479fb8e5aca35c757f234dc646fb0358509cb786
Author: Enrico Scholz <enrico.scholz@informatik.tu-chemnitz.de>
Date:   Tue Dec 14 21:41:02 2010 +0100

    set SO_REUSEADDR for client sockets
    
    This allows to run dhcp-forwarder and a dhcp server like dnsmasq (with
    'bind-interfaces' option) on the same host.
    
    Patch was provided by Stefan Keller <sk@open.ch>.
