cp-tree.h: Declare flag_use_repository.

	* cp-tree.h: Declare flag_use_repository.
	* pt.c (do_decl_instantiation): Don't complain about duplicate
	instantiation with -frepo.
	(do_type_instantiation): Likewise.

	* pt.c (push_template_decl_real): Complain about everything
	that isn't a valid template.

	* decl2.c (import_export_decl): If -fnew-abi, class linkage doesn't
	affect inlines.
