If the .el file was not changed Emacs will load the original .eln in 'native-lisp' without having to recompile it. If the .el was modified we will recompile it in 'eln-cache' and load it, when we do this we clean-up the stale .eln present in `comp-eln-load-path'. Unfortunatelly for this case we don't do this for the last directory in `comp-eln-load-path' (as this is tipically read-only when Emacs is installed). > Question #2: can we somehow remove the stale .eln file in these > situations? I guess we should make it work for non installed case. be22cda7be should do this. Thanks Andrea
