+       Add the switch statement to AWK Mode.
+
+       * progmodes/cc-awk (awk-font-lock-keywords): Add "switch", "case",
+       "default" to the keywords regexp.
+
+       * progmodes/cc-langs (c-label-kwds): Let AWK take the same
+       expression as the rest.
+       (c-nonlabel-token-key): Allow string literals for AWK.  Refactor
+       for the other modes.
+
        Large brace-block initialisation makes CC Mode slow: Fix.
        Tidy up and accelerate c-in-literal, etc. by using the
        c-parse-state
