	Fix 980628-*.f:
	* bld.h: New `pad' field and accessor macros for
	ACCTER, ARRTER, and CONTER ops.
	* bld.c (ffebld_new_accter, ffebld_new_arrter,
	ffebld_new_conter_with_orig): Initialize `pad' field
	to zero.
	* com.c (ffecom_transform_common_): Include initial
	padding (aka modulo aka offset) in size calculation.
	Copy initial padding value into FFE initialization expression
	so the GBE transformation of that expression includes it.
	Make array low bound 0 instead of 1, for consistency.
	(ffecom_transform_equiv_): Include initial
	padding (aka modulo aka offset) in size calculation.
	Copy initial padding value into FFE initialization expression
	so the GBE transformation of that expression includes it.
	Make array low bound 0 instead of 1, for consistency.
	(ffecom_expr_, case FFEBLD_opACCTER): Delete unused `size'
	variable.
	Track destination offset separately, allowing for
	initial padding.
	Don't bother setting initial PURPOSE offset if zero.
	Include initial padding in size calculation.
	(ffecom_expr_, case FFEBLD_opARRTER): Allow for
	initial padding.
	Include initial padding in size calculation.
	Make array low bound 0 instead of 1, for consistency.
	(ffecom_finish_global_): Make array low bound 0 instead
	of 1, for consistency.
	(ffecom_notify_init_storage): Copy `pad' field from old
	ACCTER to new ARRTER.
	(ffecom_notify_init_symbol): Ditto.
	* data.c (ffedata_gather_): Initialize `pad' field in new
	ARRTER to 0.
	(ffedata_value_): Ditto.
	* equiv.c (ffeequiv_layout_local_): When lowering start
	of equiv area, extend lowering to maintain needed alignment.
	* target.c (ffetarget_align): Handle negative offset correctly.
	* global.c (ffeglobal_pad_common): Warn about non-zero
	padding only the first time its seen.
	If new padding larger than old, update old.
	(ffeglobal_save_common): Use correct type for size throughout.
	* global.h: Use correct type for size throughout.
	(ffeglobal_common_pad): New macro.
	(ffeglobal_pad): Delete this unused and broken macro.
