can't do `make-frame' with emacs 22.1 under Leopard

Why can't I `make-frame' with emacs 22.1 under Leopard?  The error  
must lie in `make-terminal-frame', which says:

error: "Not running on a Macintosh screen; cannot make a new Macintosh  
frame"

I'm running ordinary emacs 22.1 in Terminal -- the one that came  
installed with Leopard.  Never had this problem until I upgraded to  
Leopard.

I love your work.  Please advise.

This is due to the following part in the implementation of
`make-terminal-frame' in frame.c:

#ifdef MAC_OS
  if (sf->output_method != output_mac)
    error ("Not running on a Macintosh screen; cannot make a new Macintosh frame");
#else

It was added in 1999 and seems to be intended for Mac OS 8 and 9.
I've changed the above condition to #ifdef MAC_OS8, so the bug will be
fixed in Emacs 22.2.
