Subject: [PATCH] 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.
