Thanks for the hints related to the (display-time) stuff. The
 initialization problem is solved now. However, I still get troubles
 with the X window. I 'am not able to run xemacs within X. Is there any
 variable that controls the display settings or anything similar? When
 started from within X, Xemacs automatically switches back to GUI
 without complains or error messages. Do you have any experience with
 Xemacs under cygwin? 
Try starting with -display yourhost:0.0 and see if that helps
