[AUCTeX] Missing latex macros

[Brian Elmegaard]

Hi

I have GNU Emacs 23.2.1 (i386-mingw-nt5.1.2600) of 2010-05-08 on G41R2F1 
obtained from http://ftp.gnu.org/gnu/emacs/windows/ and auctex for 
windows auctex-11.86-e23.2-msw.zip from 
http://www.gnu.org/software/auctex/download-for-windows.html.

I have unpacked emacs to c:\Program Files\emacs23.2 and copied the 
contents of auctex to this directory.

I can open tex-files and compile, so it seems to work.

However, I cannot get it to do auto-completion when I insert \usepackage.

I cannot figure out what I need.

Regards,
Brian
