OK - now it looks as follow:

,----
|   /* Attempt to hunt down bug#16028.  */
|   SET_FRAME_GARBAGED (f);
| 
|   /* Added by rkrug */
|   f->fonts_changed = true;
|   
|   recompute_basic_faces (f);
| 
|   do_pending_window_change (0);

OK.

I'll leave the session open till Monday - so let me know if you need
some further information.

On Monday, I will re-compile and start again as I did this time.

Thanks,

Rainer
