The following syntax file parse.y:
=====================================
%defines
%define api.value.type union
%token <int> NUM
%%
input: NUM
{ printf("%d\n", $1); }
;
%%
====================================
causes NUM to be defined multiple times.
Excerpt from parse.tab.h:
====================================
union YYSTYPE
{
#line 59 "parse.tab.h" /* yacc.c:1909 */
/* NUM */
int NUM;
/* NUM */
int NUM;
};
================================
This causes a compile error.
Operating system: Windows 7-64
Using cygwin-32
