# Apparently Linux 2.6.27.7 has an "include dependency" problem
# preventing netfilter from being detected by configure (this may
# very well be a configure problem).
#
# This patch works around the problem by replacing the relevant
# references to linux/netfilter_ipv[46].h with references to
# linux_netfilter_ipv[46].h. These two files are created by the
# patch and simply include some extra header before the original one.
#
# For this to work, the C(XX)FLAGS variables gain an extra "-I"
# option on configure time.
