Its purpose is to tell you that Emacs loads a .elc file that is older than the corresponding .el file. See load-prefer-newer. > Why am I told this specifically, and why for > just certain files, not every one I edit? It depends on the order of byte-compilation. > Has it to do with files being `require'd before > compilation has gotten that far?
