Correct. lockfile-progs already selects the liblockfile package in its
Config.in file, but does not depend on it in its .mk file, which is
wrong. Your fix is correct.

No, that wouldn't work. By doing so, you wouldn't have the guarantee
that liblockfile is built before lockfile-progs, so the compilation of
the latter could still fail.

Yes, this issue hasn't been fixed in the latest version.

Do you want to send a proper patch so we can keep your attribution, or
do you want me to send a patch, mentioning your name ?
