Sorry for butting in. I have a macros.tex file where I collect all commonly 
used \usepackages, \newcommands and so forth. Based on advice received via this 
mailing list, I inserted the following at the beginning of the file:

---------------------------------------------------------------------------
% Following workaround required in order to get auctex to parse this file
% and update auto/macros.el properly.
\iffalse
\documentclass{article}
\begin{document}
\fi
---------------------------------------------------------------------------

There's a matching \iffalse \end{document} \fi at the end of the file.

I don't know if this workaround is still required, but I suspect it will no 
longer work once AUCTeX starts interpreting conditionals, so I have selfish 
motives for hoping a little that things will remain as they are.
