+
+        Set of changes so that "obtrusive" syntactic elements in a
+        C/C++/ObjC preprocessor line (e.g. an unbalanced string quote or
+        unmatched paren) don't interact syntactically with stuff outside
+        the CPP line.
+
+        * progmodes/cc-awk.el (c-awk-beyond-logical-line, c-awk-old-ByLL):
+        Replace c-awk-end-of-logical-line and c-awk-old-EoLL to solve an
+        off-by-one bug.
+        (c-awk-record-region-clear-NL): Replaces c-awk-before-change, with
+        a bit of refactoring.
+        (c-awk-extend-and-syntax-tablify-region): Takes some of the
+        functionality of c-awk-advise-fl-for-awk-region, which has been
+        refactored away.
+
+        * progmodes/cc-defs.el (c-clear-char-property-with-value-function)
+        (c-clear-char-property-with-value): New function and macro which
+        remove text-properties `equal' to a supplied value.
+
+        * progmodes/cc-engine.el: Comment about text properties amended.
+
+        * progmodes/cc-fonts.el (c-cpp-matchers): Make it put regexp
+        parens around "error\\|warning".
+
+        * progmodes/cc-langs.el (c-get-state-before-change-function)
+        (c-before-font-lock-function, c-anchored-cpp-prefix): new language
+        variables.
+        (c-cpp-message-directives): Handle "#warning" in C, C++ and ObjC.
+
+        * progmodes/cc-mode.el (c-basic-common-init): C and ObjC now use
+        syntax-table text properties.
+        (c-common-init): Call language specific before/after-change
+        functions at mode initialisation.
+        (c-new-BEG, c-new-END, c-old-BOM, c-old-EOM): new variables.
+        (c-extend-region-for-CPP, c-neutralize-CPP-line)
+        (c-neutralize-syntax-in-CPP): new functions.
+        (c-before-change, c-after-change): call the new language specific
+        change functions defined in cc-langs.el.
+        (c-advise-fl-for-region): new macro.
+        (awk-mode): Remove AWK specific stuff which has been refactored
+        into language independent stuff.
