Please confirm the fix? I don't have a Windows machine.

Just pulled and built. Unfortunately, I am still getting the same error. I tried GHCi like this:

Prelude> :m + Network.Socket
Prelude Network.Socket> :i SockAddr
data SockAddr
  = SockAddrInet PortNumber HostAddress
  | SockAddrInet6 PortNumber FlowInfo HostAddress6 ScopeID
        -- Defined in `network-2.6.0.2:Network.Socket.Types'
instance Eq SockAddr
  -- Defined in `network-2.6.0.2:Network.Socket.Types'
instance Ord SockAddr
  -- Defined in `network-2.6.0.2:Network.Socket.Types'
instance Show SockAddr -- Defined in `Network.Socket'

As you can see, the SockAddrUnix is simply undefined on Windows!!! Weird that Haddocks do not mention anything about it.

I tried building using both MSYS and PowerShell.

I think the answer to this SO question will help.

So, I added the following to the library section:

library
   if os(windows)
    cpp-options:       -DWINDOWS
  hs-source-dirs:    src
...

and the previous error does not appear anymore (the ifndef WINDOWS worked). However, now I am getting another error:

cbits\byteorder.c:5:23:
     fatal error: arpa/inet.h: No such file or directory
compilation terminated.

See another SO answer - on Windows, one must use winsock2.h instead of inet.h.

See network's HsNet.h for inspiration.

Just send a pull request? I'd need you to verify any fix anyways.
