Using bash aliases with auctex

[Martin]

I'm having problems getting emacs to use my bash aliases. Specifically,
when running auctex's view command on a latex buffer, xdvi gets called
with default arguments, instead of my xdvi alias that all bash shells
use. I changed the TeX-shell variable to bash

(custom-set-variables '(TeX-shell "/bin/bash") ...

but that didn't change anything. Shouldn't that make emacs read all
that's in my .bashrc file?
