+	* data/bison.simple (yyparse): Correct error handling to conform to
+	POSIX and yacc.  Specifically, after syntax error is discovered,
+	do not reduce further before shifting the error token.
+	Clean up the code a bit by removing the labels yyerrdefault,
+	yyerrhandle, yyerrpop.
+	* NEWS: Document the above.
