Except you cannot make Winsock return X_ENOTCONN.
But we don't really care because we're in control of what gets stores
into errno after Winsock calls. So instead of:
errno = WSAGetLastError ();

I'm pretty sure that other GNU applications -- that have also been

Lynx uses this:
#define SOCKET_ERRNO errno
#ifdef WINDOWS
#undef

OK. So the whole thing with errno is only necessary when dealing with
Winsock errors. For errors from, say, fopen it's fine to use errno?
Yes.
There is another possible approach. We already #define read and write
to call Winsock stuff. We could add

Okay by me.

It returns WSAENOTCONN (def'ed to ENOTCONN in
