These two (and similar ones):

#define IXDR_GET_INT32(buf)           ((int32_t)ntohl((uint32_t)*(buf)++))
#define IXDR_PUT_INT32(buf, v)        (*(buf)++ = (int32_t)htonl((uint32_t)(v)))

The first one is used as e.g.:

oa->oa_length = IXDR_GET_INT32 (buf);

All changes I did resulted in different assembler code...
