This may seem sill or I might be missing part of this conversation but
would it not be easier and just as portable to use a simpler 
implementation of retractall/retract_all rather than creating elaborate 
solutions to emulate compiler directives:
        
        myretractall(Term) :-
                retract(Term),
                fail.
        myretractall(_).

Appologies for any naivety resulting from my focus on PDC Prolog and 
restricted experience with other versions of Prolog.
