I've tried a fresh ~/.emacs file with copy-paste the above instructions. 
Carbon Emacs outputs the following error in the buffer *Messages*:

"Symbol's value as variable is void: TeX-expand-list"

and, of course, the command simpdftex doesn't go into the Command menu.
I use simpdftex by adding the command to AUCTeX via the Carbon Emacs's 
menu. A drawback is that after saving the setting, .emacs gets the 
full list of all commands '(TeX-command-list ... ).
Your method is better by adding in .emacs only the additional 
commands by the TeX-expand-list.

I wonder what might be causing the error in C.Emacs.
