>Description:

	scanf/sscanf doesn't understand %lld, %qd works ok.

>How-To-Repeat:

	cdn3[64]> cat tp.c
	#include <stdio.h>
	#include <sys/types.h>

	main() {
    	u_int64_t q = 0;
    	sscanf("4354736128", "%lld", &q);
    	printf("%lld\n", q);
	}
	cdn3[65]> cc -O -o tp tp.c
	cdn3[66]> ./tp
	59768832
	cdn3[67]> 

>Fix:

pull up rev 1.14 of lib/libc/stdio/vfscanf.c from NetBSD CVS repository.
It would be great if this could be fixed in the 4.x stable branch too.
