Use "enum" for integral constants.

Browse Source 
This is just nicer to read, I observed no speedup.

	* data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
	(yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
	(yyuser_token_number_max_, yyundef_token_): Move into...
	(yytranslate_): here.
