It seems pretty unusual to me (for make). The only way I can think to do it is have a phony target that always runs, where the recipe is a small script that compares the elements in the source with the ones in the target and deletes anything in the target that doesn't exist in the source. -- ------------------------------------------------------------------------------- Paul D.
