I first wrote :

					for (aux = rt_hash_table[i].chain ; ; aux = aux->u.dst.rt_next) {
						if (aux == rth) {
							length += ONE;
							break;
						}
						if (compare_hash_inputs(&aux->fl, &rth->fl))
							break;
					}

but had to split the too long line, so ended in the form in the patch :)


Thank you
