Yeah, they left POSIX a long time ago, probably
due to neglect it seems :-(.


As it's only in test code and it's the only use
of this function left in our code you could
fix the build to not build the target 'resolvconftest'
be editing it out of libcli/dns/wscript_build.

We did use this elsewhere but replaced it (I
remember Volker fixed this). I'll have to look
back in the git logs to see how he did it.
