cast error in MP_OBJ_NEW_SMALL_INT(). This is necessary for FreeBSD, where st_ino is of different size - If MP_CLOCKS_PER_SEC is defined on the target host, simply define CLOCK_DIV as a fraction, regardless of the value of MP_CLOCKS_PER_SEC. FreeBSD uses a non-POSIX compliant value of 128 for CLOCKS_PER_SEC
