	* decl.c (redeclaration_error_message): Complain when redeclaring
	a friend function with default template arguments (C++0x mode only).
	* cp-tree.h (check_default_tmpl_args): Declare.
	* pt.c (check_default_tmpl_args): In C++0x mode, permit default
	template arguments in function templates. Add support for checking
	the default template arguments of friend templates.
	(push_template_decl_real): Fix call to check_default_tmpl_args.
	(type_unification_real): If a template parameter has not been
	deduced but provides a default template argument, substitute into
	that default template argument.
	* parser.c (cp_parser_init_declarator): When declaring (but not
	defining!) a function template in C++0x mode, check for default
	template arguments.
