Byte-compiling your .emacs is pretty much a waste of time (you've
probably already invested more time in it than it might ever save you).
Worry about warnings while doing so is really a waste of time; but the 
standard method of suppressing free variable warnings is

(defvar TeX-auto-save)
(setq TeX-auto-save t)
