I have no better idea but I think it can be handled by 'catch exception', but I don't think guile/clisp/emacs have same procedure named 'catch' or else. > This function should return let's say 0 for guile, 1 for clisp and 2 for > emacs.

The best way is prepossess which is portable. Maybe there's better idea I didn't know? Thanks!
