Log message:
	* store-layout.c (finish_record_layout): Add free_p parameter.
	(layout_type): Pass it.
	* tree.h (finish_record_layout): Update prototype.
	
	* class.c (walk_subobject_offsets): Correct the calculation of
	offsets for virtual bases.  Correct the counting of array
	elements.
	(layout_nonempty_base_or_field): Simplify.  Correct the
	calculation of offsets to be propagated through the binfo
	hierarchy.
	(build_base_field): Avoid creating a FIELD_DECL for empty bases.
	Add the FIELD_DECL to TYPE_FIELDS.
	(build_base_fields): Adjust accordingly.
	(layout_virtual_bases): Use build_base_field.
	(end_of_class): Return a tree, not an integer.
	(warn_about_ambiguous_direct_bases): Rename to ...
	(warn_about_ambiguous_bases): ... this.
	(include_empty_classes): New function.
	(layout_class_type): Create an alternative version of the type to
	be used when as a base class type.  Do not call
	finish_record_layout until we are done laying out the class.
	* cp-tree.h (lang_type_class): Remove size, size_unit.  Add
	as_base.
	(CLASSTYPE_SIZE): Reimplement.
	(CLASSTYPE_SIZE_UNIT): Likewise.
	(CLASSTYPE_ALIGN): Likweise.
	(CLASSTYPE_USER_ALIGN): Likewise.
	(CLASSTYPE_AS_BASE): New macro.
	(DECL_INITIALIZED_P): Likewise.
	(extract_init): Remove prototype.
	(build_forced_zero_init): Rename to ...
	(build_zero_init): ... this.
	(force_store_init_value): Remove.
	* decl.c (obscure_complex_init): Remove.
	(duplicate_decls): Copy DECL_INITIALIZED_P.
	(check_initializer): Do not leave junk in DECL_INITIAL.
	(cp_finish_decl): Handle zero-initialization of entities with
	static storage duration.
	* expr.c (extract_init): Remove.
	* init.c (build_forced_zero_init): Remove.
	(build_zero_init): New function.
	(build_default_init): Use it.
	(build_field_list): Skip FIELD_DECLs for base subobjects.
	(push_base_cleanups): Likewise.
	* method.c (do_build_assign_ref): Likewise.
	(synthesize_exception_spec): Likewise.
	* pt.c (tsubst_decl): Clear DECL_INITIALIZED_P.
	(regenerate_decl_from_template): To not set DECL_INITIAL for a
	static data member whose initialization took place in its class.
	(instantiate_decl): Do not pass an initializer to cp_finish_decl
	in that situation.
	* search.c (dfs_push_decls): Skip FIELD_DECLs for base subobjects.
	(dfs_unuse_fields): Likewise.
	* tree.c (pod_type_p): Handle error_mark_node.
	(zero_init_p): Likewise.
	* typeck.c (lookup_anon_field): Skip FIELD_DECLs for base
	subobjects.
	* typeck2.c (store_init_value): Remove #if 0'd code.
	(force_store_init_value): Remove.
	(process_init_constructor): Use build_zero_init.
	
	* g++.dg/abi/empty7.C: New test.
	* g++.dg/init/pm2.C: Likewise.
