dnl Even if <net/bpf.h> were, on all OSes that support BPF, fixed to
dnl include <sys/ioccom.h>, and we were to drop support for older
dnl releases without that fix, so that pcap-bpf.c doesn't need to
dnl include <sys/ioccom.h>, the test program in "AC_LBL_FIXINCLUDES"
dnl in "aclocal.m4" uses it, so we would still have to test for it
