Summary: swig tries to call private constructor

Initial Comment:
In this test case, SWIG will generate a setter for Three::m called _wrap_Three_m_set, which tries to call Two's copy constructor (which is private).  If you change "Two m;" to "One m;" SWIG behaves correctly and doesn't generate the setter -- that extra level of inheritance seems to confuse it.  Tested with SWIG 1.3.38 & Python.

%module test;

%inline {
	struct nocopy
	{
			nocopy() {}
			
		private:
			nocopy(const nocopy&);
			nocopy& operator=(const nocopy&);
	};
	
	struct One: public nocopy {};
	struct Two: public One {};
	struct Three { Two m; };
}
