1 new commit in cc-mode: https://bitbucket.org/xemacs/cc-mode/commits/a8a9fbb96c60/ Changeset: a8a9fbb96c60 User: acm Date: 2017-09-15 15:40:14+00:00 Summary: Cope better with C++ and Objective-C protection keywords in class declarations This fix fixes the fontification of method inside a class at the time it is typed, when there is a protection keyword clause preceding it. * cc-engine.el (c-forward-keyword-clause): Handle protection keywords. (c-looking-at-decl-block): Avoid scanning forward over protection keyword clauses too eagerly. * cc-langs.el (c-protection-key c-post-protection-token): New lang defconsts and defvars. * cc-mode.el (c-fl-decl-start): When we encounter a protection keyword following a semicolon or brace, move forward over it before attempting to parse a type.
