Subject: [lftp] [PATCH] Fix building against GNU libc 2.16 (gets undefined)
X-Mailer: Claws Mail 3.8.1 (GTK+ 2.24.10; i686-pc-linux-gnu)

Martin Jansa reported[1] a bug compiling lftp against GNU libc 2.16. The
code assumes gets is defined when in 2.16 it is not. The attached
patch adds the necessary check.
