	* defaults.h (FUNCTION_ARG_REG_LITTLE_ENDIAN): New.
	* calls.c (store_unaligned_arguments_into_pseudos): Check

	(move_block_from_reg): Ditto.
	(copy_blkmode_from_reg): Ditto.
	* stmt.c (expand_return): Ditto.
	* stor-layout.c (compute_record_mode): If

	MEMBER_TYPE_FORCES_BLK even if mode == VOIDmode.
	* config/ia64/hpux.h (MEMBER_TYPE_FORCES_BLK): Set to true
	so that Structures of one field are still treated as structures.
