I didn't think getchar/putchar existed in the Atmel libc implementation..
I would suggest using a different function name and implement it differently
for either platform.
Also you'll want to be careful about the fact that the Atmel has 2 separate
address spaces (if it's an AVR anyway) which can cause problems because you
have to read from the right one.
