I guess it is IP Filter's definition of offsetof(),

% grep '^#define[[:space:]]\+offsetof(' ../../dist/ipf/netinet/*
../../dist/ipf/netinet/ip_fil.h:#define offsetof(t,m)   (int)((&((t *)0L)->m))

Maybe if you add lines such as this somewhere at the top of ip_fil.h
or ip_compat.h?

/* For offsetof() */
#if defined(_KERNEL) || defined(_STANDALONE)
#include <sys/systm.h>
#else
#include <stddef.h>
#endif
