I think the above statements mean that if immediate files are needed, they will be remade. Correct? I think it is the same as ordinary file. I think another meaning of above statements is ordinary file will be remade if they do not exist even if they are not needed. I can not imagine why they will be remade even if they are not needed? Could you show me an example please? :-) (If it is true, I think make program should be optimized by reducing the workload to remake unnecessary un-needed materials.) :-) while in the above situation, it means intermediate files will not be remade if they are not needed even if they do not exist.
