in my today's opinion two issues need to be fixed and one should be fixed with 
the patch I had posted a couple of days ago:

1) I should have considered that ram read accesses could have side effects for 
the avr architecture (auto-increment issue recognized thank's to Dimitry K.), 
2) the case of compile-time known block size of "0" has been handled 
incorrectly, and
3) I should probably have used double underscores for the library define 
symbols and function entry labels instead of a single underscore.

Open question for issue 1) was if adiw may be safely used in the library for 
all of the devices. Since the present state of eeprom functions makes use of 
adiw in the eeprom_read_word, I'd simply assume that the present library 
implementation is correct and I could use adiw for replacing the ld x+ .

Changes for issue 2) would simply involve adding a 

and 3) are straight forward. I'll try my very best to post a patch with above 
corrections until tomorrow morning, say 10 `o clock German time.?

Yours,
