I haven't looked at the code yet (can't until I sup it), but why
didn't you just wrap the BPF function calls in if_ppp.c (or wherever)
with:

#include "bpf.h"
#if NBPF > 0
...
#endif

like all of the other network interface drivers?

I also think that kernel support for PPP-deflate, etc., should be
optional.  My ISP's Livingston Portmasters don't support PPP
compression (other than VJ header comp.), so I can't use it anyway.
