Ported to libprelude-1.0.0 from gnulib commit:

Subject: [PATCH] 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.
