You can "manually" split the procedure yyaction, which is too long,  
into two and call the procedures in dependence of the parameter  
yyruleno. example:

rename procedure yyaction to procedure yyaction1

add the split at 100:

   99 : begin

          if not stripinfo then
          writeln(outfile,'(* Warning : default value for ',yyv 
[yysp-2]^.p,' ignored *)');
          hp:=new(presobject,init_one(t_default_value,yyv[yysp-0]));
          yyval:=new(presobject,init_three(t_dec,nil,yyv[yysp-2],hp));

        end;
   end;
end(*yyaction1*);

procedure yyaction2 ( yyruleno : Integer );
   (* local definitions: *)
begin
   (* actions: *)
   case yyruleno of
  100 : begin

and replace the call of yyaction(-yyn) (somewhere around line 8500 ) by:

   if -yyn < 100 then
       yyaction1(-yyn)
   else
     yyaction2(-yyn);

Probably not. It is a "Jonas Maebe class of problem" and he is  
working on it.
