In xemacs-packages/ess/lisp/essl-omg.el, there are a bunch of
modify-syntax-entry calls, including this one:
(modify-syntax-entry ?// "<" S-syntax-table) ; open comment
which is wrong because it is trying to specify two characters in
sequence as the first argument. This is causing the byte compiler to
complain. I don't know how to fix it.
