+. Added support for GNU G++ 4.0.  The x.4.5 beta takes advantage of
+  g++ 4.0's symbol visibility.  This feature is conceptually similar
+  to MS Windows "__declspec(dllexport)" DLL functionality.  Using this
+  new g++ feature results in substantially improved ACE/TAO/CIAO
+  shared library binaries.  A subset of the improvements include the
+  following:
+
+      * The number of unnecessarily exported DSO/DLL symbols is
+        greatly reduced, resulting in faster program start times.
+      * Smaller footprint.
+      * Improved performance since run-time indirection of internal
+        symbols is no longer needed.
+
+  No changes to the ACE/TAO sources were necessary to support this
+  feature since the required visibility attributes were hidden behind
+  the various "*_Export" macros (formerly only useful for MS Windows
+  DLLs) used throughout ACE/TAO.
