+
+    Fix some weird template/operator issues on OS X.
+    
+    I frankly don't understand at all what's going on here. These fixes
+    derive from:
+    
+    https://chromium.googlesource.com/chromiumos/third_party/dbus-cplusplus/+/c3f69f6be02e31521474dce7eadf6ba4f4a7ce94
+    https://chromium.googlesource.com/chromiumos/third_party/dbus-cplusplus/+/7104857773f790a549d399715482fa23d9b736cd
+    
+    Except I've dropped some changes that break the OS X build for me. Frankly, if
+    it compiles, that's good enough for me.
