Nicholas Marriott e8567098a4 Add support for Cgywin, apparently it is enough just to open the tty again in 
the server and fd passing is not necessary. Needs some ifdefs unfortunately but
no way around that and some of them can go next time we're willing to do a
protocol bump. Patch from J Raynor jxraynor at gmail dot com.
