I made the same experience having more than half a dozen Emacsen  
(four major versions) ... (for fun!)

This is the cure:

        (if (not (string-match "XEmacs" mEV))
            (progn
	        (setq custom-file (format "~/.emacs-Abrichtung-%d.el" emacs- 
major-version))
                (load (format "~/.emacs-Abrichtung-%d.el" emacs-major-version))
        ;       (add-hook 'write-file-hooks 'time-stamp)
                (add-hook 'before-save-hook 'time-stamp)
        ))

The German word Abrichtung means something like training, training a  
horse, i.e. part of a "customisation." mEV is:

        (defconst mEV (emacs-version)
          "Keep the Emacs version string,
           that is needed a few times.")


Before you put this block into .emacs you should copy the  
recent .emacs file to the new files and remove all non-custom-set- 
variables and all non-custom-set-faces, i.e. remove from top to the  
first "(custom-" line. Then remove in .emacs all contents from the  
first "(custom-" line until the end. Then you'll have some  
opportunities to adapt the two "training" files' contents to what  
each version accepts ...
