But `make' doesn't have such a concept of a dependency > that "needs to exist, but doesn't need to be older". I think (info "(make)Prerequisite Types") provides just that. (And the Features section at least doesn't explicitly say that this is unique for GNU make.) I.e. something like: %.elc: %.el | bootstrap-emacs cp $< $@ Apologies if I'm missing the point; I just wanted to point out this rarely-used make feature. Magnus
