+qemu for windows fails to use multicast socket as netdev
+
+My host OS is Windows 7 x64 SP1. I installed qemu for windows from https://qemu.weilnetz.de/w64/.The version is 2.10.1, qemu-w64-setup-20171006.exe. I run qemu with the following command:
+
+qemu-system-x86_64.exe -net nic -net socket,mcast=234.5.5.5:6000 disk1.qcow2
+
+It stopped with error:
+bind: Unknown error
+qemu-system-x86_64.exe: -net socket,mcast=234.5.5.5:6000: Device 'socket' could not be initialized
+
+Using the -netdev option has the same problem:
+qemu-system-x86_64.exe -netdev socket,id=hostnet0,mcast=234.5.5.5:6000 -device e1000,netdev=hostnet0 disk1.qcow2
+
+I tried many versions from https://qemu.weilnetz.de/w64/, but none of them could work.
+
+When I checked the source code, I think the problem is that on Microsoft Windows bind() can not use a multicast address.
+
+MSDN bind() reference
+https://msdn.microsoft.com/en-us/library/windows/desktop/ms737550(v=vs.85).aspx
+seems to have indicated the point.
+
+I changed the net_socket_mcast_create() in net/socket.c, make it bind to htonl(INADDR_ANY). After compiling, it seems to work correctly.
+
+Have you ever tried to suggest your change as a patch to the qemu-devel mailing list? See:
