[Bug-AUCTeX] minor annoyance when opening tex file in carbon emacs

[Artemio Gonzalez Lopez]

I am experiencing a minor annoyance when opening tex files in carbon  
emacs 21.1.1 (he one provided by Apple with Mac OS X 10.5 "Leopard").  
Namely, immediately after the file is opened it is marked as "not  
saved", so that if I close it without making any changes I am asked if  
I would like to save it, etc. I think this is an auctex thing, since  
it does not happen when I open other text files, or if I don't load  
auctex. Is there any setting I have unknowingly activated which is  
responsible for this strange behavior? Any help would be appreciated!

Cheers,

Artemio
