+Subject: [PATCH 1/1] Fix format-security warnings.
+
+Newer versions of GCC have the ability to warn you (or throw errors)
+about insecure format strings. Generally this is due to an omitted
+format string in the printf family of functions, and a few of those
+issues existed in the code base. They were all fixed by adding a
+trivial "%s" format string. The project now builds with
+-Werror=format-security.
