Uhm.  All the other things work great here, but if I modify
display-completion-list to add a with-suppressed-warnings (whether it
has an effect or not; in the example below it's suppressing a warning
that won't be output), I get a severe compilation error.

diff --git a/lisp/minibuffer.el b/lisp/minibuffer.el
index ed610c16ee..f3182d31c0 100644
--- a/lisp/minibuffer.el

        (princ (buffer-string)))

Here's the error:

make[1]: Entering directory 
  ELC      minibuffer.elc

In display-completion-list:

    arguments, but accepts only 1

Uhm...  anybody want to hazard a guess at why it fails or where I should
poke around to see what I've messed up?
