What storage is being done here?

If storing items, I would stay with defines, but for internal use, I would
think that enums provide a better style.

Granted, compilers don't enforce type checking on them, but, if a function
says it takes something of a certain type, or a switch statement is done
against a veriable of a certain type, then it's easier for the programmer
to remember what's going on.

Plus, just plain saving having to manually give the defines different,
monotonically increasing values.  And it just plain looks better, in my

#define REMOVE_KEY       269     /* 0x10D */ 
#define MOUSE_KEY        270     /* 0x10E */ 
#define DO_NOTHING       271     /* 0x10F */ 


typedef enum
  REMOVE_KEY = 269,
} event_type;

Of course, in a larger setting, the differences are much more striking.
