Snort 2.1.3RC1 includes an ability to trigger more than one alert on a 
single packet, which is great in my opinion, but this also introduces an 
interesting side effect.  For example a regular IPC$ access will trigger 
the correct 538 alert (NETBIOS SMB IPC$ share unicode access) and now also 
the 2470 alert (NETBIOS SMB C$ share unicode access), because after seeing 
IPC$, it'll also see the last two letters of that, C$,  in the packet.  So 
that one needs to be rewritten with pcre. I'll take a stab at it as soon 
as I get some time.
