It is only for compinit itself that I can get problems with that to
occur. It seems to be a little sensitive about the contents of $fpath
but the following works for me: 

  zcompile -z -U comp /usr/local/share/zsh/4.2.0/functions/Completion/**/*(.)
  zsh -f
  fpath=( ~/comp.zwc $fpath )
  setopt kshautoload
  autoload compinit
  compinit

compinit ought to be able to look inside the .zwc file so you don't
even need the functions to be there.

It'd be better if we can get it to just work.

I'd prefer if we can avoid adding to _comp_options.

This is one option and if we took it, we'd want to go with (4) so
user's can add their own entry point functions. It is just adding more
complexity though. Also, looking at the list of entry points, there are
functions I never use, making autoload +X a waste of time and memory.

Is there any reason why the -z and -k options to autoload can only be
used with +X. It would seem to me that the best would be if compinit
could use `autoload -U -z' with functions being setup to look like this:

  _autoload () {
          # undefined
          builtin autoload -XUz
  }

Would that be a possibilty?
