[ENet-discuss] Linking enet/winsock under mingw32

[Lee Salzman]

There's no need for linking against wsock32. Also, trying supplying the linker flags in this order: -lenet -lws2_32 -lwinmm

Make will fail immediately if it couldn't find the libraries, so it can find them (and I verified they are in the path)...but it's still failing. I compiled enet in the same environment, so I don't think it has to do with enet using different library versions
