C-c C-a should do it.

Sorry, I'm running Emacs 22 here.  Have a look at the cc-mode
manual.  I'm pretty sure the feature exists on Emacs 22 too.

c-toggle-auto-newline is a command, not a variable.  You need to call
(c-toggle-auto-newline 1) in an appropriate hook, probably
c-mode-common-hook.

C++ mode.

[K Hollingworth]

According to emacs I have 

GNU Emacs 20.7.1 (i386-redhat-linux-gnu, X toolkit) of Fri Mar 16 2001 on
porky.devel.redhat.com

I would like to customise c++ mode so that lines starting std::cerr are
marked in a different red as most of them are for debugging and it
would be nice to be able to spot them easily.  Is this possible?  It
would be acceptable to mark everything in the std namespace in red.

I'm a bit of a newbie with emacs so apologies as I don't know all the
terminology yet!

Look at the font-lock function in the manual. See below for an example from
my .emacs file.

M-x highlight-phrase RET std:cerr RET

In the buffer when you need it would be what I would do.

Do I need to load another package to get that?   Emacs says "no match"
when I try that command and if I try matching "highlight" I only get the
following completions:

highlight-changes-mode		   highlight-changes-next-change
highlight-changes-previous-change  highlight-changes-remove-highlight
highlight-changes-rotate-faces	   highlight-compare-with-file

Sorry about that, this function is new in Emacs 21 I hadn't noticed. 
Look for hi-lock.el if you can't use Emacs 21.  I can't find it
elsewhere I'm afraid.  You probably could adapt C++ mode, but I don't
know how.
