+Subject: [PATCH] gets() no longer exists in (e)glibc >= 2.16
+
+gnutls has already updated gnulib upstream in more recent versions
+(3.x) but apparently not in the 2.x branch that we are using.
+
+This patch comes from OpenEmbedded, and has originally been written by
+Khem Raj <raj.khem@gmail.com>.
