in Windows platform couldn't check remote was closed

/* On UDP, a connreset simply means the previous send failed.
* So we try again.
* On TCP, it means our socket is now useless, so the error passes.
* (We will loop again, exiting because the same error will happen) */

as this in wsocket.c line 256 try again but may it missing continue ? prev still IO_DONE
in if (err != WSAECONNRESET || prev == WSAECONNRESET) return err;

int socket_recv(p_socket ps, char *data, size_t count, size_t *got, 
        p_timeout tm) 
{
    int err, prev = IO_DONE;
    *got = 0;
    if (*ps == SOCKET_INVALID) return IO_CLOSED;
    for ( ;; ) {
        int taken = recv(*ps, data, (int) count, 0);
        if (taken > 0) {
            *got = taken;
            return IO_DONE;
        }
        if (taken == 0) return IO_CLOSED;
        err = WSAGetLastError();
        /* On UDP, a connreset simply means the previous send failed.

        if (err != WSAEWOULDBLOCK) {
                        if (err != WSAECONNRESET || prev == WSAECONNRESET) return err;
                        prev = err;
			//change by  2017-1-7 01:59:38 darklost.me
			//settimeout(0) is always return IO_TIMEOUT when remote server is closed!
			//maybe missing continue here?
			continue;
        }
        if ((err = socket_waitfd(ps, WAITFD_R, tm)) != IO_DONE) return err;
    }
}

in function int socket_recvfrom(p_socket ps, char *data, size_t count, size_t *got, SA *addr, socklen_t *len, p_timeout tm) the same as above

may be missing continue ?

Is it possible that this just recently got fixed with the merger of #81? Can you confirm this with the scm version?

Pretty sure this is a duplicate of #174, and the comment about possibly being fixed still applies. In any case lets track it in one issue.
