+Fix compilation with glibc-2.16.

+Patch backported from gnulib upstream:

+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.
