You can get automated dependency scanning with GNU make, it just doesn't
come built-in.  But it's not hard to achieve, especially if you have a
relatively decent compiler (like GCC).  But even without one you can do
it pretty easily.  For example there are instructions at my web site
(see the .sig).

I don't know that there will ever be any kind of automated scanner
embedded in GNU make.  To me that seems the wrong way to go... make
would need to know too much about some specific kinds of targets.  The
only automated dependency scanner I ever thought might be appropriate to
be integrated into GNU make was a very cool one that used LD_PRELOAD to
provide generic dependency tracking for any kind of target.  But, that
only works on systems that support LD_PRELOAD of course.
