+        * net/tramp.el (tramp-convert-file-attributes): Call `eql' instead
+        of `=', because `tramp-get-remote-gid' might not always return an
+        integer when expected.
+        (tramp-register-file-name-handlers): `partial-completion-mode' is
+        unknown to XEmacs.
+        (tramp-time-diff): Don't use `floor', it might fail for large
+        differences.
+        (tramp-handle-make-auto-save-file-name): For Emacs 21, set
+        `tramp-auto-save-directory' if unset in order to guarantee unique
+        auto-save file names.
