It's a common perception and one that's wrong. a b c: d foo is a shorthand for a: d foo b: d foo c: d foo Since most make variants only look at the timestamp one can avoid building a, b, and c thrice by enforcing an ordering. Make variants like clearmake may not be tricked that easily, because they keep track of much more. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
