Removing sign bit like this:

int msecs(int from) { return int((GetTickCount() - (dword)from) & 0x7fffffff); }
                                                                ^^^^^^^^^^^^^^^^

is not a good idea. There are some places in upp that rely on sign bit (e.g. httcli):

if(msecs(end_time) >= 0) {
^^^^^^^^^^^^^^^^^^^^^^^^^^
	error = NFormat("Timeout reading footer block (%d B).", body.GetLength());
	break;
}

While in other places msecs is used incorrectly (httpcli again):

while(msecs() < end_time) {

Someone forgot that ticks wrap every ~50 days (or ~25 days if sign bit is masked).
