Hi all,

on a self-compiled one-week old GNU/Emacs (commit 808f69bf), I see
the following:

  $ cd $HOME; emacs --batch --execute "(print native-comp-eln-load-path)"

  ("/home/lele/.emacs.d/eln-cache/" "/home/native-lisp/")

  $ cd /tmp; emacs --batch --execute "(print native-comp-eln-load-path)"

  ("/home/lele/.emacs.d/eln-cache/" "/native-lisp/")

Indeed, that variable is defined in src/comp.c as

  /* Temporary value in use for bootstrap.  We can't do better as
     `invocation-directory' is still unset, will be fixed up during
     dump reload.  */
  Vnative_comp_eln_load_path = Fcons (build_string ("../native-lisp/"), Qnil);

What is the purpose of that relative "native-lisp" entry?

I guess nobody has a roommate with that name, that could play dirty tricks
putting casual .eln files in his home dir, but who knows? :-)

Thanks and bye, lele.
