Looks good to me, only a few stylish comments:

+      // Calculate Aligned Size
+      // Returns a size that is larger than or equal to __size and divided by
+      // __alignment, where __alignment is required to be the power of 2.
+      size_t _Aligned_size(size_t __size, size_t __alignment)
+      { return ((__size - 1)|(__alignment - 1)) + 1; }

static size_t
_S_aligned_size...

+      bool _M_supported (size_t __x)
+      { return ((__x != 0) && (__x != 0) && !(__x & (__x - 1))); }

Documentation? Also make it static.

+  // Global memory resources
+  inline std::atomic<memory_resource*>&
+  _S_get_default_resource()

__get_default_resource.
