+Upstream-Status: Backport
+
+Remove unused variables from the code to prevent -Werror causing a build
+failure on hosts with GCC 4.6.
+
+These changes are all upstream so should not be required once we've updated
+to elfutils 0.152 or later. Therefore this patch consolidates several
+changes from elfutils upstream by Roland McGrath into a single file so that
+it's easier to remove later once we upgrade.
+Links to upstream gitweb of the consolidated commits follow:
