./:
	* dse.c (struct store_info): Rename bitmap field to bmap.  Change
	all uses.

	* c-decl.c (in_struct, struct_types): Remove.
	(struct c_binding): Add in_struct field.
	(c_binding_ptr): Define type, along with VEC.
	(struct c_struct_parse_info): Define.
	(struct_parse_info): New static variable.
	(bind): Initialize in_struct field.
	(start_struct): Remove enclosing_in_struct and
	enclosing_struct_types parameters.  Add
	enclosing_struct_parse_info parameter.  Change all callers.  Set
	struct_parse_info rather than in_struct and struct_types.
	(grokfield): If -Wc++-compat and there is a symbol binding for the
	field name, set the in_struct flag and push it on the
	struct_parse_info->fields vector.
	(warn_cxx_compat_finish_struct): New static function.
	(finish_struct): Remove enclosing_in_struct and
	enclosing_struct_types parameters.  Add
	enclosing_struct_parse_info parameter.  Change all callers.  Don't
	set C_TYPE_DEFINED_IN_STRUCT here.  Call
	warn_cxx_compat_finish_struct.  Free struct_parse_info and set to
	parameter.  Only push on struct_types if warn_cxx_compat.
	(finish_enum): Only push on struct_types if warn_cxx_compat.
	(declspecs_add_type): Add loc parameter.  Change all callers.
	Change all error calls to error_at.  Pass loc, not input_location,
	to pedwarn calls.  Warn if -Wc++-compat and a typedef name is
	defined in a struct.  If -Wc++-compat and parsing a struct, record
	that a typedef name was used.
	* c-parser.c (c_parser_declspecs): Get location to pass to
	declspecs_add_type.
	(c_parser_struct_or_union_specifier): Update calls to start_struct
	and finish_struct.
	* c-tree.h (struct c_struct_parse_info): Declare.
	(finish_struct, start_struct): Update declarations.
	(declspecs_add_type): Update declaration.
objc/:
	* objc-act.c (objc_in_struct, objc_struct_types): Remove.
	(objc_struct_info): New static variable.
	(objc_start_struct): Pass &objc_struct_info, not &objc_in_struct
	and &objc_struct_types, to start_struct.
	(objc_finish_struct): Likewise for finish_struct.
objcp/:
	* objcp-decl.h (start_struct): Remove in_struct and struct_types
	parameters.  Add struct_info parameter.
	(finish_struct): Likewise.
testsuite/:
	* gcc.dg/Wcxx-compat-15.c: New testcase.
