This should fix #604.

I've added a flake.nix file in #606 that can be used to run the tests using cross compilation and wine on a x86_64-linux machine with nix installed. Just run nix flake check. I also included a .github/workflow/haskell-nix.yml file to run it (untested).

This PR does seem to fix the failures it has with socket, but there are some others as well.

Failures:

  .\System\IO\Temp.hs:114:3:
  1) Network.Socket.bind successfully binds to a unix socket
       uncaught exception: IOException of type OtherError
       Network.Socket.socket: failed (Address family not supported by protocol family (WSAEAFNOSUPPORT))

  To rerun use: --match "/Network.Socket/bind/successfully binds to a unix socket/" --seed 243449885

  tests\Network\SocketSpec.hs:135:15:
  2) Network.Socket, ifNameToIndex and ifIndexToName, convert a name to an index and back
       not expected: Nothing

  To rerun use: --match "/Network.Socket/ifNameToIndex and ifIndexToName/convert a name to an index and back/" --seed 243449885

  tests\Network\Socket\ByteStringSpec.hs:218:41:
  3) Network.Socket.ByteString.recvMsg receives truncated flag
       expected: MsgFlag {
                   fromMsgFlag = 256
                 }
        but got: MsgFlag {
                   fromMsgFlag = 0
                 }

  To rerun use: --match "/Network.Socket.ByteString/recvMsg/receives truncated flag/" --seed 243449885
