The old code was:

        int chars;
        char req_buf[CTL_MAX_DATA_LEN];

                req = req_buf;
                req_end = req_buf + sizeof(req_buf);
#define REQ_ROOM        (req_end - req)

                        chars = strlen(buf);
                        if (REQ_ROOM - chars < 1)
                                break;

The new code is:

        size_t chars;

                        if (REQ_ROOM <= chars)
                                break;

The old if didn't work after chars changed to size_t.
