That's the first thing a gnulib net/if.h replacement header should
provide then, since I believe the net/if.h header needs to be
self-contained according to POSIX.

It would be interesting to see if the self tests works even if you make
the above modification, though.  Also try running it with a command line
parameter and check that it prints all the host interfaces on your
machine.
