> What about the (num == -1) case? Does it cope with EINTR and EAGAIN?

Yeah, that's already handled a bit further down, just out reach of the context.
 The entire block of code (compacted to save space) is:

                if (num == 0)
                        goto err;       /* descriptor closed */
                else if (num > 0)
                    numbytes += num;
                else {
                    switch (errno) {
#ifdef EINTR
                        case EINTR:
#endif
#ifdef EAGAIN
                        case EAGAIN:
#endif
                            /* No error, try again */
                            break;
                        default:
                            ret = -1;
                            goto err;   /* failure */
                        }
