[avr-libc-dev] EEPROM.h Suggestion

Hi Guys, 

Just been porting ButtLoad's hacked-together EEPROM support over to the (now 
M169 compatible) AVRLibC version. Works fine, but I have a suggestion. 

Is it possible to add to the library a #ifdef so that the current EEPROM value 
is checked inside the write routine so that the value is only written if it 
differs? This would impose a speed penalty but it would preserve EEPROM life. I 
picture it as using a define (such as #define __EEPROM_CHECKPREV) before the 
inclusion of the EEPROM header to turn on the checking functionalty.
