>Example from Win32:
>C:\Temp\iperf>iperf -s -u -B 239.0.0.1
>------------------------------------------------------------
>Server listening on UDP port 5001
>Binding to local address 172.23.100.254
>Receiving 1470 byte datagrams
>UDP buffer size: 8.0 KByte (default)
>------------------------------------------------------------

>I would expect it to bind to the multicast address and join the multicast 
>group like it does on Linux.  Please advise if there is a fix or 
>workaround.  Thank you.
