bug#19625: 24.4.51; packages using eieio need recompilation when switching to emacs-25

[Thierry Volpiatto]

Hi,

packages using eieio when compiled with emacs-24.4 should not need a
recompilation when switching to emacs-25:

1) Switch to emacs-24

2) Install and compile helm from https://github.com/emacs-helm/helm
or melpa.

3) Run from helm directory ./emacs-helm.sh

4) Switch to emacs-25

5) Repeat 4) and you have an error:
Too many arguments to `defclass'.
