There was this mail from Microsoft, offering support in case Windows 10 
would raise console problems with cygwin:
https://cygwin.com/ml/cygwin/2015-04/msg00623.html
While this was particularly about the console, maybe this offer could be 
used for a request to provide official documentation of that system 
call, so it could then be used?
