Bison H file generation

[Yair Grosu]

Hi,

I have been using Bison with the -d option to generate a header file to be used by flex.

I have defined the '#define YYSTYPE double' in the grammar file, but the output ignores this and the header file only contains the type as int as follows:

#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# define yystype YYSTYPE /* obsolescent; will be withdrawn */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

extern YYSTYPE yylval;

This goes for the Gnuwin32 from SourceFourge and the Cygwin version.

Thanks

Yair Grosu
