Subject: [PATCH 1/1] stdio: don't assume gets any more
Gnulib intentionally does not have a gets module, and now that C11
and glibc have dropped it, we should be more proactive about warning
any user on a platform that still has a declaration of this dangerous
interface.

However, we believe that sprintf can be used safely, and is more
efficient than snprintf in those safe cases; and as proof of our
belief, we use sprintf in several gnulib modules. So this header
