First of all, I'm not sure it is the right thing that
global-auto-composition-mode depends on emacs-basic-display

languages/scripts, I've just install a change that makes
global-auto-composition-mode not depend on

For those who don't know what we are talking here, this is
relevant only to emacs-unicode-2 branch.
