looks like the change would be very easy.  only comp_matched function
would need to be rewritten and prefix length would play no role in
comparison.

if someone later would like to have this option implemented, i'll
include new version of comp_matched function below for the records.

/*
 * Compare matched gateways based on priority, and randomized weight.

static int comp_matched(const void *m1, const void *m2)
{
    struct matched_gw_info *mi1 = (struct matched_gw_info *) m1;
    struct matched_gw_info *mi2 = (struct matched_gw_info *) m2;

	/* Sort by priority */
	if (mi1->priority < mi2->priority) return 1;
	if (mi1->priority == mi2->priority) {
	    /* Sort by randomized weigth */
	    if (mi1->weight > mi2->weight) return 1;
	    if (mi1->weight == mi2->weight) return 0;
	    return -1;
	}
	return -1;
