Windows change?

Hi,

I'm trying to install auc-tex on XP and my old init files (that work on 
several other computers running XP) don't work.  I get: "File mode 
specification error: (void-variable TeX-auto-global".  This seems to be 
a result of calling (autoload 'tex-mode "tex" no-doc t) in tex-site.el. 
  I tried commenting that out, which gives no error, but C-c C-c doesn't 
work in any case.  Did something change?  I saw a complicated looking 
install thing at "Installation under MS Windows", but I don't see a 
date, so I don't know if that's new or old.  Plus doing seems complicated.

Thanks,

Sean
