I find it annoying because it means .elc files change on every compilation. Diffing two trees containing .elc files reports spurious differences for every single .elc file due to this (admittedly, you can avoid this by using diff -I). Is this timestamp useful in any way? ^ permalink raw reply [flat|nested] 5+ messages in thread

Please have only their hair cut. ;-) The full comment is like this: ;;; Compiled by user@host on Fri Mar 8 08:59:18 2013 ;;; from file /path/to/simple.el ;;; in Emacs version 24.3 ;;; with all optimizations. Gentoo has a script called emacs-updater [1] that uses the version information from the third line, by matching the following regexp: [Ee]macs version \([0-9].*\) It would be nice if this part of the comment could be preserved.
