* cp-tree.h (CPTI_CLEANUP_TYPE): New macro.

	* cp-tree.h (CPTI_CLEANUP_TYPE): New macro.
	(cleanup_type): Likewise.
	(search_tree): Change prototype.
	* decl.c (local_variable_p): Adjust for new interface to
	search_tree.
	(check_default_argument): Likewise.
	* error.c (dump_expr): Handle INIT_EXPR.
	* except.c (expand_throw): Don't make cleanup_type a local static.
	* expr.c (cplus_expand_expr): Don't handle NEW_EXPR.
	* init.c (build_new): Call build_new_1 directly, rather than
	building a NEW_EXPR.
	(build_new_1): Tidy.  Don't build a VEC_INIT_EXPR except when
	processing file-scope initializers.

	* tree.c: Include splay-tree.h
	(no_linkage_helper): Adjust for new interface to search_tree.
	(search_tree): Pass around pointers to tree nodes, rather than the
	nodes themselves.  Handle VEC_INIT_EXPR.

	(mapcar): Handle VEC_INIT_EXPR.
	(target_remap): New variable.
	(bot_manip): Use it.
	(bot_replace): New function.

	function and presented with an INIT_EXPR assignment
	* Makefile.in (tree.o): Depend on splay-tree.h.
