This patch helps a lot. I couldn't even get through an install before.
But please don't remove qemu-old yet: I'm using UDP multicast sockets to
build virtual networks, and they fail on 0.13.0:
$ sudo qemu -m 128 -no-fd-bootchk \
-hda virtual.img -boot n -nographic \
-net nic,vlan=0,model=rtl8139,macaddr=52:54:00:12:34:03 \

-net tap,vlan=1,script=no \
-net nic,vlan=3,model=rtl8139,macaddr=52:54:00:23:03:03 \
-net socket,vlan=3,mcast=230.0.0.1:10003
setsockopt(SOL_IP, IP_MULTICAST_LOOP): Invalid argument
qemu: -net socket,vlan=3,mcast=230.0.0.1:10003: Device 'socket' could not be
initialized
Works fine if I comment out the last two lines.
this should fix it. can you try it please?

Can you also check the rest of socket.c for the other uses of
setsockopt(), specifically
the SO_REUSEADDR cases?
