+** Mule-UCS compilation problem.
+
+Emacs of old versions and XEmacs byte-compile the form `(progn progn
+...)' the same way as `(progn ...)', but Emacs of version 21.3 and the
+later process that form just as interpreter does, that is, as `progn'
+variable reference.  Apply the following patch to Mule-UCS 0.84 to
+make it compiled by the latest Emacs.
