     - Make get_interface_address() function work properly again; stop
       guessing the wrong parts of our address as our address.
 
+  o Code simplifications and refactoring:
+    - Change our header file guard macros to be less likely to conflict
+      with system headers.  Adam Langley noticed that we were conflicting
+      with log.h on Android.
