+
+       * tex-buf.el (TeX-next-error): Do not pass `reparse' argument to
+       `next-error' in XEmacs as it is not supported.
+       (TeX-error-overview-frame, TeX-error-overview-buffer-name): Move
+       before their first use in order to prevent a runtime error in
+       XEmacs and GNU Emacs 21.  Reported by Ikumi Keita.
+       (TeX-parse-TeX): Manually set `item' to nil when
+       `TeX-error-last-visited' is negative.
+       (TeX-error-description-error, TeX-error-description-warning)
+       (TeX-error-description-tex-said): Set to nil in XEmacs and GNU
+       Emacs 21.  Reported by Ikumi Keita.
+
+2014-07-13  Mos� Giordano  <address@hidden>
+
+       * latex.el (TeX-latex-mode): Add second argument to
+       `local-variable-p', mandatory in XEmacs.  Suggested by Ikumi
+       Keita.
+
+       * preview/preview.el (preview-dump-state): Ditto.
+
+       * style/biblatex.el ("biblatex"): Ditto.
+
+       * tex.el (TeX-how-many): Make the function return a number also in
+       XEmacs and Emacs 21.  Suggested by Ikumi Keita.
+
+2014-07-12  Mos� Giordano  <address@hidden>
+
+       * tex-buf.el (TeX-error-description-error): Do not use the
+       `default' display, not supported by GNU Emacs 21 and XEmacs 21.4.
+       (TeX-error-description-warning): Ditto.
+
+2014-07-11  Mos� Giordano  <address@hidden>
+
+       * tex-buf.el (TeX-error-description-error): Make face definition
+       XEmacs compatible.
+       (TeX-error-description-tex-said): Ditto.
+       (TeX-error-description-help): Ditto.
+
+       * tex.el (nil): Handle the case of a non-available crm.el with a
+       `condition-case', instead of using the third argument of
+       `require', not recognized by XEmacs 21.4.
+       (and): Check whether dbus support is available before requiring
+       dbus.el.
