      Fix c-tentative-buffer-changes to be nestable in c-save-buffer-state · 0662a2909c5e
      Alan Mackenzie authored
      * cc-defs.el (c-benign-error): Move earlier in the file for the benefit of
      c-tnt-chng-cleanup.
      (c-tentative-buffer-changes, c-tnt-chng-record-state, c-tnt-chng-cleanup):
      Enhance such that a buffer-undo-list of t is handled specially, so that a nil
      isn't consed onto it.  Thus garbage collection can't later remove the (nil
      . t) from the end of the buffer-undo-list, causing an infinite loop.

      CC Mode: Move the handling of keyword auto into type handling for C++. · 7b896f471f96
      Alan Mackenzie authored
      This should allow auto, const, static, ... to be in any order.
      
      * cc-engine.el (c-forward-type): New return value 'no-id for when auto
      precludes the parsing of a type identifier.  Adapt processing for this.
      (c-forward-decl-or-cast-1): Use the new facility from c-forward-type.
      
      * cc-langs.el (c-type-modifier-prefix-kwds): Insert the value of
      c-no-type-kwds into the value.
      (c-no-type-kwds, c-no-type-key): New lang consts/vars, basically "auto".
      (c-typeless-decl-kwds, c-modifier-kwds): Remove "auto" from the C++ value.

      C++ Mode: Modernize the fontification of "using" · 1eafa3102499
      Alan Mackenzie authored
      Since "using" is now used in three distinct ways in C++, write a special
      function to handle these rather than attempting to adapt the old regular
      expressions.
      
      * cc-fonts.el (c-font-lock-declarators): Amend to allow the argument TYPES to
      be a face.  This face is given to the declarator being processed.
      (c-font-lock-single-decl): Make an argument to c-font-lock-declarators nil or
      t, not merely nil or non-nil.
      (c-complex-decl-matchers): Include c-font-lock-c++-using in the C++ value of
      this variable.
      (c-font-lock-c++-using): New function.
      
      * cc-langs.el (c-using-kwds, c-using-key): New lang consts/vars.
