Even if I eliminate the cast from

#define FUNCTION_ARG_SIZE(MODE, TYPE)   \
  ((((MODE) != BLKmode \
     ? (HOST_WIDE_INT) GET_MODE_SIZE (MODE) \
     : int_size_in_bytes (TYPE)) + UNITS_PER_WORD - 1) / UNITS_PER_WORD)

There is no 'operator/' for the poly_int.

Problem doesn't affect 64-bit hpux and linux.
