One of the more common cases where you use identifiers only different in case 
is for union fields inside structures, e.g.:

struct abc {
  int a, b, c;
  union {
    char Array[4];
    long Whole;
    } wa_union;
  };

#define array wa_union.Array
#define whole wa_union.Whole

which allows you to rerefence the union fields in your program without
having to supply the union name, i.e.  abcvar.array[2]  in stead of 
abcvar.wa_union.Array[2].
