I think I understand why that is. > I don't have a handle on your new scheme yet. Adding the above dependency means that witness-emacs will be recreated everytime a C source file is changed, so every change to a C source file will cause 2 dumps: one to `bootstrap-emacs' (via witness-emacs) and another to `emacs'. So it defeats the whole idea behind `witness-emacs'. I don't have a better answer yet, tho, Stefan
