For the following code, the indentation of the code isn't right for GNU
style (C-x h TAB after writing the code):

/* Output after default (auto)indentation in GNU Emacs (TAB is used sometimes) */
char *words[] = {
		 "good",
		 "better",
		 "best"
};

The GNU style is (as done by the program GNU indent):

/* They should be indented with 2 spaces (and not TABs)
char *words[] = {
  "good",
  "better",
  "best"
};

Tabs are also add for indentation when defining enums:

typedef enum {
	      GOOD,
	      BETTER,
	      BEST
} test;

The following might be better (2 spaces, and no TABs):

typedef enum {
  GOOD,
  BETTER,
  BEST
} test;
