bug#249: Minibuffer-only frame with bold default font is not bold

[Stefan Monnier]

[ This bug was introduced by the old font-backend but seems not to
  be fixed by the new code. ]

I use a minibuffer-only frame and have the following setting for it:

  (setq minibuffer-frame-alist
        `((minibuffer . only)
          (top . -1) (left . 0) (user-position . t)
          (height . 1) (width . 256) (user-size . t)
          (vertical-scroll-bars . nil)
          (menu-bar-lines . 0)
          (tool-bar-lines . 0)
          ,(case window-system
             (mac '(font . "-apple-monaco-bold-*-*--12-*-*-*-*-*-*-*"))
             (t '(font . "-misc-fixed-bold-r-normal-*-13-*-*-*-*-*-*-*")))
          (background-color . "grey75")
          (name . "emacs-minibuffer")))


With the new unicode code, the default font is not bold any more, making
it much more difficult to find and read.
Could someone give me a hint where the problem might be?

PS: This same problem showed up during the Emacs-22 development and was
fixed before the 22.1 release, see
