Follow-up Comment #2, bug #30552 (project avr-libc):

For device ATTiny43U: 
the patch given for bug30569 defines ADC and ADCW to 0x04 (using _SFR_MEM16
macro) while datasheet clearly says that address of ADCL is 0x24 and that of
ADCH is 0x25.

The  following diff uses _SFR_IO16 instead of _SFR_MEM16. _SFR_IO16 adds an
offset of 0x20. I think this is appropriate.
