I'm sorry to say that you have made a few incorrect assumptions about
Cygwin and apparently gone to some effort to implement something which
didn't need to be implemented.
1) Cygwin has a functioning socketpair which can be used in select().
It is not implemented using _pipe and, AFAIK, has never been implemented
using _pipe since _pipe in Cygwin isn't really intended to be used
that way.
2) Pipes can be used in select() in Cygwin, anyway.
3) All of the discussion about "win32" isn't really appropriate for
cygwin.
4) See http://cygwin.com/contrib.html for a description of how to
contribute to the Cygwin code base. I wish it was as easy as just
pointing to a web page and say "take it" but it isn't.
So, thanks for thinking of us, but this isn't anything that we can
use.
