1st question: (BISON)
-------------

I am looking for the equivalent of yacc++ on the PC.
I have already the gnu compiler and the bison tool.
But as i read the documentation i couldn't find anything about an 
option to switch to bison++ or something like that.
I know that with flex you can use the \-+ option to specify flex 
to generate a C++ scanner class.

Is there anybody aware about such an option for bison, or is 
there another tool for such a thing.



2nd question: (FLEX)
-------------

Another question, what do you mean exactly by a C++ scanner 
class. My problem to be precise is that i redefine the YYSTYPE 
macro. Normally by default it is defined as an int. But when i 
will compile i want to redefine this macro such as:

	#define YYSTYPE cYaccStackElem

With:
class cYaccStackElem
{
 public:
  CString ystr;
  CcType ytype;
  cYaccStackElem ()(ytype=VOID_TYPE;);
  CString ystrAdd;
};

So my second question is to know if this C++ scanner class allows 
me to write my source code as above.
