Possible, yes, but I don't think it is practical. Even though the
general steps to compile and install elisp are the same for GNU Emacs
and XEmacs, there are also a lot of finicky little implementation
details that are different. There would not be a lot of joined code, I
think.

While looking for some examples I found that not many eclasses currently
do this, so perhaps this is good advice for others as well? Petteri's
own java-utils-2.eclass does support this, obviously, and so will the
xemacs eclass.

Kind regards,
