The former uses the Carbon APIs, and the latter uses the earlier APIs.

So MAC_OS does not necessarily mean HAVE_CARBON.

In Emacs 23, removal of the whole Mac OS Classic (8 or 9) support is
much more likely to happen than that of the Carbon support.  Then this
distinction will become meaningless in that version.  Of course, the
documentation for cpp defines is still useful to read the Emacs 22
code.
