you might get a situation where unnecessary make-runs or builds are done, just 
to satisfy the new dependency chains you create, *if* make knows how to build 
dependency files in the first place.
Paul's 'advanced' method builds upon the concept of dependency files being something make 
need not "know anything about" IIRC, in order not to do too much.
Greg's suggestion is the way to go if your users may delete dependency files
