-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>.
