Start Emacs like this:

1. emacs -Q --eval "(require 'ediff)"
2. emacsclient -c
3. C-h v ediff-window-setup-function
=> ediff-setup-windows-multiframe

Now start Emacs like this:

1. emacs -Q --daemon --eval "(require 'ediff)"
2. emacsclient -c
3. C-h v ediff-window-setup-function
=> ediff-setup-windows-plain

I haven't tried debugging this, but my first guess is that
ediff-setup-windows-multiframe requires non-nil window-system but (still
guessing) when there is no frame window-system evaluates to nil.
