Let's try to compare two .elc files to see if they are different.

$ diff -a *.elc
2,4c2,4
< ;;; Compiled by jidanni <at> jidanni1.jidanni.org on Sat Jul 25 03:33:07 2009

Well, what would really help is if along with mentioning which .el file
the .elc file was compiled from, would be adding checksum and some ls -l
information about the .el file. Else it is really hard figuring out if
the .elcs are really derived from the .els currently nearby. (And no,
nobody wants to compile again just to see.)
