branch: master
commit 78923c5f4e26d3cb9fbaf0dbf2d04c523482e52c
Author: Alan Mackenzie <acm@muc.de>
Commit: Alan Mackenzie <acm@muc.de>

    C++ Mode - Fontify "class Foo {\n  ~Foo() noexcept;" correctly
    
    This fixes bug #49787.
    
    * lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): (In `if' form just
    before CASE 8) Remove the (not ...) around the (looking-at
    c-after-suffixed-type-maybe-decl-key).
    
    * lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Add
    `c-not-decl' to the values of c-type which are erased at the start of a
    fontification.
