	* objc-encoding.h (obstack.h): Do not include.
	(util_obstack, util_firstobj): Do not declare.
	(encode_field_decl): Updated prototype to return a tree and take a
	single tree argument.  Updated comments.
	* objc-encoding.c (util_obstack, util_firstobj): Made static.
	(objc_encoding_init): New.
	(encode_field_decl): Existing function renamed to encode_field and
	made static.  New encode_field_decl wrapper function added.
	(encode_aggregate_fields): Update call to encode_field_decl to
	call encode_field.
	* objc-next-runtime-abi-02.c (obstack.h): Do not include.
	(util_obstack, util_firstobj): Do not declare.
	(build_v2_ivar_list_initializer): Updated call to

	(util_obstack, util_firstobj): Do not declare.
	(build_ivar_list_initializer): Updated call to encode_field_decl.
	* objc-act.c (objc_init): Use objc_encoding_init.
