>Description:
	The CVS version of GCC accepts redefinition of default
	arguments.  This is illegal C++ and generates an error on
	SGI Irix C++ and Compaq C++.  It should be rejected on gcc as
	well.
>How-To-Repeat:
	Compile the following code.  It should generate an error, but
	gcc accept.

		class T {
		public:
		  T(int i = 0);
		private:
		  int m_i;
		};

		T::T(int i = 0) // This line is illegal
		  : m_i(i)
		{
		}

	It is only legal to specify default parameters in the prototype.
