My *guess* would be that it doesn't, as I think current versions of  
WinPcap support x86-64, so the code is at least 64-bit clean.  I think  
it has a compiler that translates the BPF filter program to machine  
code; that compiler supports 32-bit x86 (and there's an x86-64 version  
originally done for FreeBSD, which WinPcap might have picked up), but  
there isn't one for Itanium, so, if there's no #ifdef, you might have  
to disable that.  (BPF still works, it just runs interpretively.)

No, because WinPcap includes kernel-mode code (because it requires it,  
in order to tap into the networking stack).
