Sounds like a good idea. Cygwin just recently completely changed their
X11 libraries, upgrading(?) to current xorg standards. So, lots of
things presumably broke. I'm no longer running Windows, so I don't keep
up with cygwin any more.

I'd go ahead and just commit removing -DSYSV; it might be that people
that haven't yet upgraded to the new cygwin stuff will find problems.
If so, Scott can fix them :-) More likely, we'll just require an
up-to-date cygwin.

[One idea: if /usr/X11R6/lib exists, we are probably in the old R6-land;
if not, libraries are probably in /usr/lib.]
