Using mac command key as normal command key in emacs

[Gilbert Harman]

I am trying to figure out how to allow the mac command key to function as
the normal command key in the yesterday's CVS version,  (GNU Emacs 22.0.50.1
(powerpc-apple-darwin8.3.0) of 2005-11-18 on Gilbert-Harmans-Computer.local)

I have in my .emacs
  (setq mac-pass-command-to-system t)
  (setq mac-command-key-is-meta nil)
but it now seems that the variable "mac-command-key-is-meta" is no longer
recognized.  And the setting for "mac-pass-command-key-to-system" is being
ignored.

There is a variable "mac-command-variable" with the following
Documentation:
 Modifier key assumed when the Mac command key is pressed.
 The value can be `alt', `ctrl', `hyper', or `super' for the respective
 modifier. The default is `meta'.

But none of these allows the command key to function as the standard command
key.  (But something "killed" in emacs can still be "pasted" into another
mac program with command-V.)
