I have a very very simple parser and in 2.3 I could define some
additional functions using YYSTYPE just by including the generated
header because it defined:
#if ! defined YYSTYPE && ! defined YYSTYPE_IS_DECLARED
typedef int YYSTYPE;
# define yystype YYSTYPE /* obsolescent; will be withdrawn */
# define YYSTYPE_IS_DECLARED 1
# define YYSTYPE_IS_TRIVIAL 1
#endif
however, now in 2.4 this is what I get there:
#if ! defined YYSTYPE && ! defined YYSTYPE_IS_DECLARED
# define yystype YYSTYPE /* obsolescent; will be withdrawn */
# define YYSTYPE_IS_DECLARED 1
#endif
This strikes me as a bug, specially because you actually define
YYSTYPE_IS_DECLARED to 1 without defining YYSTYPE.
I also tried defining YYSTYPE in the .y itself but it had absolutely
no influence in the generated .y.
