How to make tab to indent by 4 spaces (be it spaces or true tabs like in makefiles). By default my emacs inserts 2 spaces in C files and tabs indent by 8 in makefiles.

Thanks.

    I have this in my emacs config file to set tab width to 4 globally:

    ; Turn on tabs                                                                                                       
(setq indent-tabs-mode t)                                                                                             
(setq-default indent-tabs-mode t)                                                                                     

;; Bind the TAB key                                                                                                   
(global-set-key (kbd "TAB") 'self-insert-command)                                                                     

;; Set the tab width                                                                                                  
(setq default-tab-width 4)                                                                                            
(setq tab-width 4)                                                                                                    
(setq c-basic-indent 4)
