No idea as to what is going wrong.

The plan is that cygwin starts X11 on startup (-c startx) in the cygwin
dos-box; then X11 opens a xterm when it starts; and that xterm launches
grass. The '-n "$DISPLAY"' part should protect against it trying to start
grass from the cygwin dos-box outside of X11. What does:
  echo $DISPLAY
say from the cygwin dos-box prompt (not the xterm).
