Brad, I think there is a problem with these changes.
Consider next use case:

    struct const_item{ const int values[10]; };
    void test_const_item( const_item x = const_item() );
    struct const_container{ const const_item items[10]; };
    void test_const_container( const_container x = const_container() );

This code compiles fine with gccxml, but const_container class
description doesn't contain artificial default constructor. At the
same time, it contains default copy constructor.

I am not C++ expert, but I think the class should have default constructor.
