[pkg-dhcp-devel] Bug#616290: Patches solving FTBFS of isc-dhcp for GNU/Hurd

Hello,

I've noticed a -17 version was uploaded, but unfortunately without
hurd patches.  For the record, here they are again, refreshed:

- fix_ftbfs4hurd.dpatch which is actually what is upstream changes to
  fix build on hurd, to be added before ldap backend fixes in 00list.
- patch which adds the above patch in 00list, and adds the
  inetutils-tools dependency on hurd-any to get inetutils-ifconfig.
- dhclient-script.hurd and dhclient-script.hurd.udeb, which I have
  refreshed against the latest Linux version, to be added in debian/

Could you please apply them?

Samuel
