System: NetBSD this 1.6K NetBSD 1.6K (THAT) #147: Fri Jan 10 18:49:06 EST 2003     andrew@this:/usr/src/sys/arch/i386/compile/THAT i386

>Description:

	the printf(3) man page describes the z modifier for integer
	types that are size_t and ssize_t.  try to use them and gcc
	warns you that it has no idea what they are.

>How-To-Repeat:

	% cat > size_t.c << EOF
	#include <sys/types.h>
	main() {
		size_t s = 437;
		printf("%zu\n", s);
	}
	EOF
	% cc -Wformat size_t.c
	size_t.c: In function `main':
	size_t.c:2: warning: unknown conversion type character `z' in format
	% 

>Fix:

	tweak gcc (src/gnu/dist/toolchain/gcc/c-common.c, around line
	1635) to shut up about it?  import a new gcc?
