Is "/usr/X11R6/bin" in your PATH? It isn't there by default, and it
needs to be added manually.

This message shouldn't prevent you from using X. I had warnings about
the .Xauthority file, but X still worked.

I experienced this problem when trying to run "xdm". I didn't find a
solution, but then I didn't look very hard. It *might* work if you log
into windows as "root". AFAICT, Cygwin uses your Windows username.

In any case, I have managed to get GRASS working with Cygwin and
XFree86 on Win98. However, I've only done the most minimal testing (I
use Linux almost exclusively; the Windows partition exists for games
and, occasionally, testing GRASS on Cygwin).
