Why aren't you using the %union declaration.

If I do this 

.y


------------------------------

%{

/* C includes and globals */

%}

%union{
     double dval;
}
%token name

%%

list : name

-----------------------------

and compile with -d I get this

.h

---------------------------

typedef union {
   double dval;
} YYSTYPE;
#define name 258

extern YYSTYPE yylval

----------------------------
