[Pkg-utopia-maintainers] Bug#558975: avahi: FTBFS on hurd-i386: wrong network interface backend used

Package: avahi
Version: 0.6.25-1
Severity: important

Hi,

currently[1] avahi does not compile on GNU/Hurd.

The scenario is the following: in avahi-core, three different network
interface backends,
- iface-linux.c (compiled if linux/netlink.h is found)
- iface-pfroute.c (compiled if net/route.h is found)
- iface-none.c (compiled in the remaining cases)
on Hurd, it finds net/route.h so it tries to compile the pfroute backend; the
problem is that the backend uses net/if_dl.h and the rt_* network stuff,
unavailable on the Hurd.
The proposed patch extends the configure check for net/route.h by adding
net/if_dl.h among the includes needed for the check, so it will pass if both
net/route.h and net/if_dl.h are available.

Although the pfroute backend is used by *freebsd-*, the change shouldn't
affect it.
