I still maintain that --enable-depend should be on by default. We're
absurdly optimizing towards saving a handful of cycles in scenarios
which are usually bottlenecked by other things (build boxes spend more
times on tests and such), rather than optimizing for developer time. I
don't know how many people failed setting --enable-depend by now, but it
definitely goes into several hundres of wasted ours territory.
