Where are there both yytokentype and the corresponding macro definitions?

[Peng Yu]

Hi,

I see both yytokentype and the corresponding macro definitions in
y.tab.h. It sounds like just one of them will be sufficient. Why are
there both of them?

/* Token type.  */
#ifndef YYTOKENTYPE
# define YYTOKENTYPE
  enum yytokentype
  {
    IF = 258,

/* Tokens.  */
#define IF 258
