I don't see that in my copy.  Perhaps I edited it but I don't recall 
doing so.

The definitions for the vectors of the second UART are contained in 
the "else" part of a conditional where the initial test is for the 
mega644 (non-P version).  Consequently, they will be present when 
compiling for the mega324P and mega644P.

#if defined(__AVR_ATmega644__)

# define _VECTORS_SIZE 112

#else /* !defined(__AVR_ATmega644__) */

/* USART1, Rx Complete */
/* USART1 RX complete */
#define USART1_RX_vect			_VECTOR(28)
#define SIG_USART1_RECV			_VECTOR(28)

/* USART1 Data register Empty */
/* USART1 Data Register Empty */
#define USART1_UDRE_vect		_VECTOR(29)
#define SIG_USART1_DATA			_VECTOR(29)

/* USART1, Tx Complete */
/* USART1 TX complete */
#define USART1_TX_vect			_VECTOR(30)
#define SIG_USART1_TRANS		_VECTOR(30)

# define _VECTORS_SIZE 124

#endif /* defined(__AVR_ATmega644__) */
