I have a similar question... is there a way to set c-offsets-alist on a
file-by-file basis
using the headline comments (or whatever they are called) like this:
/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*-

Here is an example .emacs I found at :

;; Here's a sample .emacs file that might help you along the way.  Just

;; change some of the actual values.

(defconst my-c-style
  '((c-tab-always-indent        . t)
    (c-comment-only-line-offset . 4)
    (c-hanging-braces-alist     . ((substatement-open after)
    (c-hanging-colons-alist     . ((member-init-intro before)
                                   (case-label after)
                                   (label after)
                                   (access-label after)))
    (c-cleanup-list             . (scope-operator
    (c-offsets-alist            . ((arglist-close . c-lineup-arglist)
                                   (substatement-open . 0)
                                   (case-label        . 4)
                                   (block-open        . 0)
                                   (knr-argdecl-intro . -)))
    (c-echo-syntactic-information-p . t)
  "My C Programming Style")

;; offset customizations not in my-c-style
(setq c-offsets-alist '((member-init-intro . ++)))

;; Customizations for all modes in CC Mode.
(defun my-c-mode-common-hook ()
  ;; add my personal style and set it for the current buffer
  (c-add-style "PERSONAL" my-c-style t)
  ;; other customizations
  (setq tab-width 8
        ;; this will make sure spaces are used instead of tabs
        indent-tabs-mode nil)
  ;; we like auto-newline and hungry-delete
  (c-toggle-auto-hungry-state 1)
  ;; keybindings for all supported languages.  We can put these in
  ;; c-mode-base-map because c-mode-map, c++-mode-map, objc-mode-map,
  ;; java-mode-map, idl-mode-map, and pike-mode-map inherit from it.
  (define-key c-mode-base-map "\C-m" 'c-context-line-break)

(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

I hope that helps...
