which version can work with XEmacs ?

[KIRIYAMA Kazuhiko]

Hi list,

I'm still using XEmacs because many additional non-official
packages that I made were installed. Now I'm makeing slime
package but failed compiling on lib/ert-x.el (full log in [1]):

  # bind (error-info)

  # (unwind-protect ...)

I know that slime does not work on XEmacs stable
version. What I want to know is which slime version could be
run on xemacs-21.4.24. My compiling environments are as
follows:
