I built the pretest 23.0.91 under my home directory on
machine A, and ran it on machibe B which mounts the same
home direcotory, but Emacs starts up normally.  The value of
the variable data-directory is
"/home/handa/emacs-23.0.91/etc/".

Next, I moved etc/charsets to etc/charsets.tmp and ran Emacs
on machine A and B.  In both cases, this message was shown.

Error: charsets directory (/home/handa/emacs-23.0.91/etc/charsets) does not exist.
Emacs will not function correctly without the character map files.
Please check your installation!

So, the shown directory is the correct place.

I fixed it.  Now even if Emacs can't find etc/charsets,
Emacs can be used at least for handling ASCII text.
