Hi Hans, You are right, "YYSTYPE" is defined in .yacc.h as "%union" directive.

I haven't used that combination, but %union just implements YYSTYPE using a C/C++ 'union'. So from that point of view, I can see there are no problems. The pointer type YYSTYPE* is perhaps there, because C does not admit the C++ reference type YYSTYPE& in function arguments.
