Is this code correct?

Hello,

I am trying to get pump working on Fedora Core 2 Test 1 and I happened
to notice this code snippet in the dhcp.c handleTransaction function:

	switch (pumpUptime() & 4) {
		case 0: if (nextTimeout >= 2) nextTimeout--; break;
		case 1: nextTimeout++; break;
	}

it seems to me that case 1: could never occur because you are anding it
with 4?  Or am I missing something?

Thanks
