Note that GCC commonly uses custom iteration macros, e.g.:

  FOR_EACH_BB_FN(bb, fn)
    {
      do_stuff;
    }

and cinoptions that get the braces-in-switch case wrong should get constructs
like the above right.

(to get gnu-style autoindent in Vim, I've been using
http://www.vim.org/scripts/script.php?script_id=575 and would adjust braces in
switch by hand if need arose; the script is probably very close to one of
approaches posted in this thread, but I haven't checked)
