	* tree-data-ref.h (SUB_CONFLICTS_IN_A): Wrap SUB argument in brackets.
	(SUB_CONFLICTS_IN_B, SUB_LAST_CONFLICT, SUB_DISTANCE): Likewise.
	(DDR_A): Wrap DDR argument in brackets.
	(DDR_B, DDR_AFFINE_P, DDR_ARE_DEPENDENT, DDR_SUBSCRIPTS): Likewise.
	(DDR_LOOP_NEST, DDR_INNER_LOOP, DDR_SELF_REFERENCE): Likewise.
	(DDR_REVERSED_P): Likewise.
