If that is really an issue, then I'd do either

(unless (fboundp 'buffer-substring-no-properties)
  (defalias 'buffer-substring-no-properties 'buffer-substring))

or if the semantics of buffer-substring in those versions cause
problems to software using buffer-substring-no-properties (I don't
think so)

(unless (fboundp 'buffer-substring-no-properties)
  (defun buffer-substring-no-properties (start end)
    use-whatever-those-old-versions-support-then))

...in the compatibility code.

However, I would be interested to know which versions you found not
to support buffer-substring-no-properties.  Concerning Emacs, 19.34
supports it so the only problem could be XEmacs and I don't have
access to old versions of XEmacs, so I can't check.
