Problem with parsing in 11.55

Hi all,

I have a problem with parsing (or using the parsed information) of my
TeX documents with auchtex 11.55. It worked fine with 10.0g. Emacs used
is 21.3.

The situation:

I use "\usepackage{...,a4}" in my documents. This should give me a "View
command" like "xdvi -paper a4 ..." according to the rexexp in TeX-view-style
in tex.el. But I only get "xdvi  test.dvi" as view commend.

"TeX-parse-self" and "TeX-auto-save" are set. The "auto/test.el"
file shows that the "a4" string was parsed correctly:
   (TeX-add-style-hook "ttt"
    (lambda ()
       (TeX-run-style-hooks
        "a4"
        ...

Do you have any idea what I have done wrong? Do you need more information?

Thanks a lot for your help
