OK. I see that works, now why? I'm assuming that the difference
between bar: and bar: ; is that GNU Make thinks that it's updated bar in
the latter case, but in the former it does not.
What I'm not sure about is why $? contains bar if I do bar: How does
that come about? Is that because bar: is a 'FORCE' target and hence GNU
Make is pretending it's up to date and hence it gets put into $?
