I understand. But aren't listed sources explicit dependencies?

I was trying to make a static dependencies automake style. IIRC += on
foo_DEPENDENCIES isn't support just yet (I have a test case to report
back to Akim on). So I was just trying to understand the logic from an
automake point of view.

I'm happy with --enable-dependency-tracking... but will all the end
users? I'm automaking squid, which while not the most popular package
around, is pretty heavily used in ISP circles.
