+	(endtoken, accept): these.
+	* src/reader.c (reader): Set endtoken's default tag to "$end".

+
+	* src/reader.h, src/reader.c (gram_error): ... can't get
+	yycontrol without making too strong assumptions on the parser
+	itself.
+	* src/output.c (prepare_tokens): Use the real 0th value of
+	token_translations instead of `0'.
+	* src/parse-gram.y (yyerror): Don't rely on yycontrol being
+	visible here.
+	* data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
+	for the time being: %locations ought to provide it to yyerror.
