Summary:  Sleep.h omission for atmega48/88/168 family

Original Submission:  To support the ATMega48/88/168 family, the sleep_mode() 
#define in sleep.h file needs to include a branch for "if SMCR defined".  The 
set_sleep_mode() function had this branch, but not sleep_mode().  The SE bit 
resides in the SMCR register on these devices.


#if defined(DOXYGEN)
extern void sleep_mode (void);
#else
# if defined (SMCR)
#  define sleep_mode() 
        {                                              
     SMCR |= _BV(SE);                          
         __asm__ __volatile__ ("sleep" "nt" :: ); 
         SMCR &= ~_BV(SE);                         
        }
# else
#  define sleep_mode() 
        {                                              
         MCUCR |= _BV(SE);                          
         __asm__ __volatile__ ("sleep" "nt" :: ); 
         MCUCR &= ~_BV(SE);                         
        }
# endif
#endif

Attached is a proposed fix. It is based on V1.6 of sleep.h, since I get the 
following compiler error at the lines where I call set_sleep_mode in 1.7 (and 
1.6.2.1):  

error: parse error before '}' token

during compilewhen it inserts the
