Re: [Emacs-diffs] Changes to emacs/lisp/ChangeLog

[Richard Stallman]

    I think that Eli's idea of renaming play-sound (now in C) to
    play-sound-internal and just adding

      (unless (fboundp 'play-sound-internal)
         (error "This Emacs binary lacks sound support."))

    at the beginning of real play-sound (which can be in Lisp after that) is
    also good solution. What do you think?

Either way.

I won't argue strenuously against it.
