    CC Mode: Set parse-sexp-lookup-properties for every mode
    
    This fixes a bug reported and diagnosed by Campbell Barton
    <[email protected]> on the emacs-devel list.
    
    * lisp/progmodes/cc-mode.el (c-basic-common-init): Set
    parse-sexp-lookup-properties or (for XEmacs) lookup-syntax-properties
    for every CC Mode mode.
