>Description:
	Compiling netbsd-2 source fails in lib/libc/string/wcschr.c,
revision 1.2.8.1 (pull-up of 1.3):

/usr/src/lib/libc/string/wcschr.c: In function `wcschr':
/usr/src/lib/libc/string/wcschr.c:47: warning: implicit declaration of function `__UNCONST'
/usr/src/lib/libc/string/wcschr.c:47: warning: return makes pointer from integer without a cast

*** Failed target:  wcschr.o

>How-To-Repeat:
	cd /usr/src	# netbsd-2 as of 2005-06-01
	./build.sh -U distribution
>Fix:
	Declaring __UNCONST as in lib/libc/stdio/vfprintf.c solves the
problem for me:
