I think the general idea this is hinting at is a dependency on the full build rules and on the dependency tree itself. IIRC Solaris make has a related feature, and there have been proposals for this for GNU make (maybe a SoC one?), but AFAIK no code yet. Anyway such an approach would sound like a more useful idea to me. Cheers, Ralf
