Tony,

If all you want is to insert a tab character at the beginning of a 
line when you type the tab key, try adding this to your .emacs file:

(add-hook 'c-mode-hook
	(function (lambda ()
		(substitute-key-definition
		'c-indent-command 'self-insert-command c-mode-map))))

(add-hook 'c++-mode-hook
	(function (lambda ()
		(substitute-key-definition
		'c-indent-command 'self-insert-command c++-mode-map))))

If, while you are at it, you also want to define the size of a tab 
as, say, 3 spaces, make it:

(add-hook 'c-mode-hook
	(function (lambda ()
		(substitute-key-definition
		'c-indent-command 'self-insert-command c-mode-map)
		(setq tab-width 3))))
