/contrib/ports/win32 already includes a netif driver using packet.lib, it seems you are using a different netif driver? Unless there's a specific need to do so, I'd suggest to use the existing driver, as it does work.
The contrib/win32 pcap related code cannot be compiled with the latest pcap.
The pcap code I use is not the problem.

There's no goto code in '/contrib/ports/win32/sys_arch.c'!
sys_timeouts_mbox_fetch() is in core/timres.c. I user cvs-1.8
It has a "goto again".
This is where timeouts are processed and mail-box is read.

Please try the complete (and up-to-date!) win32 port instead of using only parts of it and being suprised it doesn't just work.
The contrib pcap code cannot be compiled with latest pcap.
The problem was the "crude" ethernetif.c as in comes in cvs.
I had to add a low-level reader thread (as in older code):
...
/* Do whatever else is needed to initialize interface. */
/* EHTERNET_THREAD_PRIO is set to 0. */
sys_thread_new("ether_input", ethernetif_input, netif, 0, 0);
} /* end low_level_init() */
....
Than add a loop in the reader ethernetif_input():
/* move received packet into a new pbuf */
while (1)
{
p = low_level_input(netif);
/* no packet could be read, silently ignore this */
if (p == NULL)
/*return;*/
continue;
/* points to packet payload, which starts with an Ethernet header */
ethhdr = p->payload;
switch (htons(ethhdr->type)) {
/* IP or ARP packet? */
case ETHTYPE_IP:
case ETHTYPE_ARP:
#if PPPOE_SUPPORT
/* PPPoE packet? */
case ETHTYPE_PPPOEDISC:
case ETHTYPE_PPPOE:
#endif /* PPPOE_SUPPORT */
/* full packet send to tcpip_thread to process */
if (netif->input(p, netif)!=ERR_OK)
{ LWIP_DEBUGF(NETIF_DEBUG, ("ethernetif_input: IP input error\n"));
pbuf_free(p);
p = NULL;
}
break;
default:
pbuf_free(p);
p = NULL;
break;
} /* switch ther type */
} /* while true */
