If you're using the emacs D mode, you may have noticed that indentation of "else static if" clauses isn't handled properly.
There's a quick fix if you have access to the cc-mode files that come with your emacs installation.
This was tested with CC-mode 5.31.4. (see M-x c-version to get your version).
So to the main emacs lisp directory. And find lisp/progmodes/cc-engine.el. Open it and search for this comment:
Add an 'or' clause to that block of code that checks for 'static' following else. Should now look basically like this:
Now M-x byte-compile-file the file, and restart emacs.
Should be fixed now.
