Bug in gellmu.el under Emacs 21 (13 Nov 2001) This is essential for use of "gellmu.el" after upgrading to GNU Emacs 21, which was released on 28 Oct 2001. It is not needed with prior versions of GNU Emacs. This bug fix applies to version (0.7.3) of "gellmu.el" that is found in the tarball gellmu-074.tgz posted to CTAN on 2001/07/26. (The tarball will probably not be updated before January 2002.) At line 2632: REPLACE: (setq jre (concat "#" jslot)) WITH: (setq jre (concat "#" (number-to-string jslot))) After making this change to "gellmu.el" the byte-compiled file "gellmu.elc" must be rebuilt. That may be done inside emacs after saving the change by running the command "byte-compile-file", i.e., M-x byte-compile-file.
