Endian does matter and you have to compensate for every machine you  
target. Look for macros for "network byte order", these are big- 
endian and when used on a big-endian machine the data falls thru and  
nothing is done, but on a little-endian machine the bytes get re- 
ordered.

Just off hand I don't find any endian macros in avr-gcc.
