Surprisingly, I don't think anybody answered your question correctly
yet. So here's my lame attempt ....

Anyways, it's incompatible now due to changes in 23.1. You'll have to
compile with 22, I suppose, which will still work with 23.

(quoting from NEWS):

"During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files.
As a result, byte-compiled files containing non-ASCII characters can't
be read by earlier versions of Emacs.  Files compiled by Emacs 20, 21,
or 22 are loaded correctly as `emacs-mule' (whether or not they
contain multibyte characters).  This takes somewhat more time, so it
may be worth recompiling existing .elc files which don't need to be
shared with older Emacsen."
