+        <strong><blink>WARNING:</blink></strong> The default behavior of
+        the ACE Makefiles is to add <code>-fno-exceptions</code> to egcs
+        (and g++ starting with version 2.8.0) invocations.  This disables
+        exception handling support.  On Solaris/sparc and Linux/alpha, it
+        results in a 25 percent reduction in the size of libACE.so.  To enable

+        <code>make</code> command line invocation, or to your
+        <code>$ACE_ROOT/include/makeinclude/platform_macros.GNU</code>.

         <LI>With g++ 2.8.0, an internal compiler error is raised when
         trying to compile ACE_Map_Manager instantiations.  One workaround
         is to disable optimization.  The easiest way to do that is:
