+From 18ac1e26f756dd47fef33f5f706b0ec8fa696216 Mon Sep 17 00:00:00 2001
+From: Thorsten Glaser <tg at mirbsd.de>
+Date: Thu, 31 Jul 2014 16:29:41 +0930
+Subject: __progname[] is provided by libc
+
+Rename local variable to tftpd_progname to avoid a clash with glibc
+global symbols and work around Debian bug #519006 (Closes: #564052).
+
+[ hpa: specifically, double-underscore symbols in C are reserved for
+  the implementation, i.e. compiler/libc. ]
