+        decltype(_VSTD::declval<_Alloc>().construct(_VSTD::declval<_Pointer>(),
+                                                    _VSTD::declval<_Args>())),
+        void
----------------
I think you should replace this `)))` with `)), void())` for absolute correctness (e.g. `construct` might plausibly return a pointer to the constructed object, and I think C++03 is okay with that).
Otherwise, awesome, this looks like what I'd expect. :)
