A defvar with no initvalue just suppresses a byte-compiler warning about
said variable being undefined. It doesn't actually define the variable,
so I think that line should stay there, to stop the compiler complaining
about an undefined variable in

  (set-syntax-table awk-mode-syntax-table)

(So by the way I think this means cc-bytecomp-defvar is no longer
needed. Also cc-bytecomp-defun can be replaced by declare-function.)

I saw from the ChangeLog that cc-fonts was the most recent part of
cc-mode to be changed, so I tried reverting that commit. To make it take
effect, I deleted the old cc-fonts.elc rather than recompiling it.
