do you say so because you tend to non-recursive Makefiles?
(I lurk on this list for some time)

We use recursive Makefiles with good results (build time, scalability) 
here, but we have to use the "basic" auto-dependency for the reason above.

(Note to everyone: please, don't mention the "harmful" paper for the xth time
