Re: iconify-frame and make-frame-visible messages in echo area

[Richard Stallman]

    Yes, now I remember I'd also seen these messages before when using
    speedbar, which I also have from the cedet package.  The messages are
    caused by dframe-handle-make-frame-visible and
    dframe-handle-iconify-frame in speedbar/dframe.el.  Comment out the
    message lines in those functions and the messages are gone, also when
    php-mode is loaded.

There is no subdirectory called speedbar in Emacs, and no file called
dframe.el.  Is this code in Emacs?
