When used, the macro still overrides it, which might cause confusion if one 
happens to use both (like the old definition happens to linger). That is,
  %define api.value.type {a_type}
produces in .hh parser class:
  #ifndef YYSTYPE
    /// Symbol semantic values.
    typedef a_type semantic_type;
  #else
    typedef YYSTYPE semantic_type;
  #endif
