[collectd] [PATCH] libiptc: Included a copy of xtables.h and libxtc.h.
Sebastian Harl
sh at tokkee.org
Thu Oct 2 15:02:18 CEST 2008
The shipped copy of "xtables.h" is now used instead of the one possibly
available on the system. This avoids possible inconsistencies between the
shipped version of libiptc and the one available on the system. Also, it
removes the dependency on the iptables development files.
