Hmm, so I was close.  Should I error out ifndef(PFIL_HOOKS), or is the
preferred tack to build anyway and just let the system crash if an
interface is removed out from under an srt (or pppoe or etc), or what?
It appears to me that the stuff in pfil.c doesn't exist without
PFIL_HOOKS (or ipf or pf, which I definitely do not want to depend on).
