	byacc
	
>Description:

	when ports/lang/objc compiled
	This reults into a compiler error:

byacc -d yacc.ym
byacc: 6 shift/reduce conflicts
byacc: 48 reduce/reduce conflicts
cp -p y.tab.h yacc.h
cp -p y.tab.c yacc.m
/data/image/usr/ports/current/objc/work/bin/objc -c -DNDEBUG -O2 -I. -noI -I../../include/objcrt -I../../include/objpak 
-I../oclib yacc.m
yacc.m:6: fatal: syntax error "static"
Portable Object Compiler 3.1.33 (c) 1997, 98, 99, 2000, 01, 02.
Distributed under the terms of the GNU LGPL.
*** Error code 1

	byacc generates some incorectd lines:

#include <stdlib.h>
#ifndef lint
#ifdef __unused
__unused
#endif
static char const
yyrcsid[] = "$FreeBSD: src/usr.bin/yacc/skeleton.c,v 1.37 2003/02/12 18:03:55 davidc Exp $";
#endif


>How-To-Repeat:

	build ports/lang/objc

>Fix:

	Please check and see why byacc generates "__unused"

Workaround:
	CFLAGS += -Dlint to avoid the lines generated.
