class.c (make_local_function_alias): New function.

2004-08-18  Bryce McKinlay  <mckinlay@redhat.com>

	* class.c (make_local_function_alias): New function. Create local
	alias for public method DECL.
	(make_method_value): Use make_local_function_alias.
	* parse.y (craft_constructor): Don't special-case anonymous classes.
	Always set ctor_name to init_identifier_node.
	(lookup_method_invoke): Call layout_class_method when creating
	anonymous class constructor.
