Details:

because atmega48 E2END is 0xff in IO.h E2END < 0x100 will 

define # if E2END > 0 

# define EEAR _SFR_IO8(0x1E) 

# endif 



so complier result EEAR is _SFR_IO8(0x1E) 



but atmega48 EEAR is SFR_IO16(0x21) true not  _SFR_IO8(0x1E).

So i add  && !defined(__COMPILING_AVR_LIBC__) && !defined in io.h. 





//add && !defined(__AVR_ATmega48__) by tom.zhang 2005.1.23 

#if E2END < 0x100 && !defined(__COMPILING_AVR_LIBC__) &&
!defined(__AVR_ATmega48__) 

# undef EEAR 

# if E2END > 0 

# define EEAR _SFR_IO8(0x1E) 

# endif 

# undef EEARH 

#endif
