Maybe because poe.el's code seems to provide better compatibility with
ancient Emacs and XEmacs.  For example, in the Emacs definition of
make-temp-file, I see MUSTBENEW arg of write-region is used, which is
missing in XEmacs 21.4.

Right.  I think we could get rid of such a eval-and-compile from several
places.
