No, not at all.

This behavior looks natural to me.

Thanks for your help, anyway.

The Message buffer even contains these lines (without me doing C-c C-n):
--------------------------------------------------------------------------
Applying style hooks...
Loading c:/Documents and Settings/jcsantos/My 
documents/temp/auto/test.el (source)...done
Loading c:/Program Files/Emacs/site-lisp/auctex/style/amsmath.elc...done
Loading c:/Program Files/Emacs/site-lisp/auctex/style/amstext.elc...done

Loading c:/Program Files/Emacs/site-lisp/auctex/style/article.elc...done
Applying style hooks... done
--------------------------------------------------------------------------

Therefore Emacs loads the test.el file and then the style files related
to amstex. It's rather strange why it does not work.
