Fix alignment of a SHORT variable

Browse source 
typedef struct _COORD {
  SHORT X;
  SHORT Y; // I wanted to take this...
} COORD, *PCOORD;

typedef struct _CONSOLE_SCREEN_BUFFER_INFO {
  COORD      dwSize;
  COORD      dwCursorPosition; // ...of this one
  WORD       wAttributes;      // But it's combined with first 2bytes of this
  SMALL_RECT srWindow;
  COORD      dwMaximumWindowSize;
} CONSOLE_SCREEN_BUFFER_INFO;

If wAttributes has non-zero value, the code breaks.
