It looks like #603 might have broken the socket function (at least on WINE).

Haskell.nix uses iserv-proxy-interpreter.exe to run TH code under WINE. Since the release of network-3.2.8.0 this has been failing with:

iserv-proxy-interpreter.exe:Network.Socket.setSockOpt:failed(Badprotocolopt
ion(WSAENOPROTOOPT))
iserv-proxy: Network.Socket.connect: <socket: 11>: does not exist (Connection refused)

I think what is going on is that the socket function in iserv-proxy-interpreter (the part running under WINE) is failing and then the iserv-proxy connect function fails (since there is nothing to connect to.

I think the error is coming from this call https://github.com/haskell/network/pull/603/files#diff-32af11237764f85b335f809887f47a50b4ef46f94ba462283f8a9a80e669fa65R126

My guess is that this works ok on Windows (since the network GitHub tests are passing), but fails on WINE.
