auc-tex and C-c C-c with Makefiles

Hi

Lately I have started to use a Makefile with each LaTeX document and 
divide them into many smaller subdocuments, which are 
compiled/preprocessed etc by make.

I am using emacs and AUCTeX so I wonder if I can somehow change emacs 
to start make when I press C-c C-c instead of latex. My "make" command 
defaults to making dvi and pdf, and then displaying the pdf on screen.

Finally, I am using Mac OS X, and when I use C-c C-c "Other" and "make" 
it compiles the LaTeX, but the "open" command which executes preview 
(in the Makefile this is) does _not_ open up a new window. It _does_ 
open a new window when run from command-line with "make" or "make show" 
with my Makefile, however, so I wonder what makes it not work under 
emacs (restricted shell??)

Thanks for any advise!
