New patch attached. OK for mainline? Tested by looking at the

	* stor-layout.c (start_record_layout): Initialize  
remaining_in_alignment.
	(debug_rli): Output value for remaining_in_alignment.
	(update_alignment_for_field): Unconditionalize
	ms_bitfield_layout_p code. Handle non-bitfield fields. Remove
	extra alignment code.
	(place_field): Don't realign if ms_bitfield_layout_p. Unconditionalize
	ms_bitfield_layout_p code. Rewrite handling of structure fields.
	* tree.h (record_layout_info_s): Remove prev_packed.
	* doc/extend.texi (ms_struct): Add documentation of format.
