+	* tao/CDR.cpp: 
+	* tao/GIOP.cpp: 
+	  I was able to remove a memory allocation on the client side by
+	  playing some tricks with the underlying Data_Block.
+
+	* tests/CDR/basic_types.cpp: 
+	  The ORB was destroyed before the test was run, hence all the
+	  Typecodes were invalid.
+
+	* tests/Param_Test/tests.cpp: 
+	  Disabled several DII tests because they will not compile.
