Move the token type and YYSTYPE in the parser class. * data/lalr1.cc (stack.hh, location.hh): Include earlier. (parser::token): New, from the moved free definition of tokens. (parser::semantic_value): Now a full definition instead of an indirection to YYSTYPE. (b4_post_prologue): No longer included in the header file, but in the implementation file. * doc/bison.texi (C+ Language Interface): Update. * src/parse-gram.y: Support unary %define. * tests/actions.at: Define global_tokens_and_yystype for backward compatibility until we update the tests. * tests/calc.at: Idem. (first_line, first_column, last_line, last_column): Define for lalr1.cc to simplify the code.
