That's from a normal shell prompt though, right? It must be set in the
environment of the CGI script that's forked from the lighttpd. Try a
simple CGI that just runs "printenv" and see if it's set there. The
reason it seems to come up in CGI scripts is that often the environment
is cleansed of all but certain permitted variables, and it seems that
SYSTEMROOT is the casualty of this. It's a situation particular to
Cygwin, as win32 native code would know not to remove it, whereas its
meaningless to stuff written for posix/unix.

I've never heard of the CYGWIN_ROOT variable before.
I think the problem is that when you go to use a socket function,
eventually the win32 winsock functions get called, and they depend on
having SYSTEMROOT set in the environment.
