FWIW, this is what Bookmark+ uses, based on some input from Michael:

(defun bmkp-same-file-p (file1 file2)
  "Return non-nil if FILE1 and FILE2 name the same file.
If either name is not absolute, then it is expanded relative to
`default-directory' for the test."
  (and (equal (file-remote-p file1) (file-remote-p file2))
       (string= (file-truename (expand-file-name file1))
                (file-truename (expand-file-name file2)))))
