Hi Stuart,
thanks for the hint, I made one further step.

You must use libbind's headers, too: -I/usr/local/include/libbind
Just for the record, it is not -I/usr/local/include/libbind but
-I/usr/local/include/bind
This works fine with my example test program, but my full program I want
to port fails miserably:

The error however seems to come from libbind itself, inside __res_init.
I wonder however why the small example works, which was extracted.
res_init() has no parametrers.
It would probably make sense to apply the diff suggested in that thread
though, as it fixes this case and I don't see a downside (it isn't enough
for some programs which grovel deeper in struct _res, e.g. mtr, but it
seems it fixes enough common cases to be useful).
Here's a complete diff including tedu's suggestion.
I suppose you intend to patch libc to handle this simple case without
resorting to libbind?
