+  o Minor fixes (threads, comments):
+    - Silence unused variable warnings in find_cipher_by_id
+      Unused variable warnings were still generated under some versions
+      of OpenSSL. Instead, make sure all variables are used under all
+      versions of OpenSSL.
+      Patch by "teor".
+      Fix on 496df21c89d1, not in any released version of tor.
