    Fix LyX server on Windows
    
    On some recent Windows versions, GetLastError() may also return
    NO_ERROR instead of ERROR_IO_PENDING during an overlapped write
    operation to a pipe. This was confusing the state machine in
    Server.cpp so that replies to commands were scheduled but were
    never actually output.
