Ok, I have to understand a thing (as you might have guessed I am still
using 11.53), how is auctex supposed to be loaded:

    -  It is automatically loaded nothing has to be done auctex
       replaces the standard Latex mode. This is what you say below right.

    -  If so what would cause (require 'tex-site) in the init file?

Ok my fault.

Ok the el file is basically empty the elc file not:

auto-loads.elc

That seems to me a good idea :)

It seems reasonable to me, that is as I understand I should NOT
include the tex-site file? 
What happens to people who upgrade from 11.53 to 11.84 and have their 
(require 'tex-site) in their init file. Do they get a warning?

To summarise. It seems that I should exclude tex-site?
