symbolic links overwritten in Emacs 21 for Mac OS X

[Mitchell L Model]

Symptoms:

I edit a file I referred to by a path that was a symbolic link, e.g. 
~/TEMP, when ~/TEMP is a symbolic link to ~/STUFF/TEMP.

I save the file.

~/TEMP is no longer a symbolic link; it contains the changes I made, but 
~/STUFF/TEMP does not.

___________

The real file should be edited and the symbolic link left alone.

This happens with the double-clickable Emacs 21 for Mac OS X on Mac OS 
10.2.3, but not for /usr/bin/Emacs -nw executed from the terminal, 
though both claim to be "21.3.50.6 of 2002-11-27 on Bluey.local" and 
configured --without-x and prefix=/usr.
