So to go back to the initial discussion point how do you propose to solve
the following?

christos

#define	syscallarg(x)								\
		union {								\
			register_t pad;						\
			struct { x datum; } le;					\
			struct {						\
				int8_t pad[ (sizeof (register_t) < sizeof (x))	\
					? 0					\
					: sizeof (register_t) - sizeof (x)];	\
				x datum;					\
			} be;							\
		}
