From 405c98a4e3e0a6c0d9380852e2e82dbeca7edf56 Mon Sep 17 00:00:00 2001
From: Alan Modra <amodra@gmail.com>

Subject: 	* rcparse.y: Remove newcmd rule.  Move rcparse_discard_strings
 	call to rules that need no lookahead.  Check for no lookahead.

	* rclex.l (get_string): Correct "strings" list handling.
	* resrc.c (read_rc_file): Discard strings.
