disable format security warnings
We pass strings to printf directly a lot. Some distros enable some flags in their gcc by default like -Wformat-security. With these two things, we end up with a lot of build warnings like so: loginutils/chpasswd.c:42:3: warning: format not a string literal and no format arguments [-Wformat-security] But we don't care. Our focus is first and foremost on size, so adding a lot of dummy calls like: - printf(some_constant_string); + printf("%s", some_constant_string); is pointless bloat. Disable this warning flag if the compiler supports it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
