Tested against: rip-int build b24 on Solaris.

Summary:
When the custom marshaller, incorrectly leaves off data on the stream, while unmarshalling custom value types it throws an org.omg.CORBA.Marshal exception.
The ORB should be able to skip the extra data.

The attached tar file contains a test case that illustrates this problem. To run the tests:
1. untar the file
2. Point the Makefile to the right build locations (This requires changes to the "To be changed" section in the Makefile.
3. Type make at the prompt.

The second test case testOverWrites writes extra data onto the stream while marshalling. This data is left on the stream while unmarshalling. This should not cause an exception to be thrown. However, currently it throws an org.omg.CORBA.MARSHAL exception
