The fact that it doesn't work out of the box might mean that he's
using the new completion system. In that case he needs to use the
_ignored completer, as in:

  zstyle ':completion:*' completer _complete _ignored


And if he's using the new completion system, this:

can be solved, too. One only needs to not set $fignore, but instead
use the ignored-patterns style, like so:

  zstyle ':completion:*:complete:*:(all-|)files' \
      '?*~' '?*.(o|log|aux|...)' '(|*/)CVS'
                 ^^^^^^^^^^^^^
                    whatever suffixes one wants to have ignored

And finally: the _ignored completer can also be customized, see the
manual/info or Peter's guide (from www.zsh.org).
