I tested compiling and linking for the following targets:

10 and 100 Mbit Ethernuts using WinAVR-20030913
10 and 100 Mbit Ethernuts using ICCAVR 6.30
ATmega103 using WinAVR-20030913
GameBoy Advance using GNUARM (arm-elf-gcc 3.4.3)

No errors, great!

I agree.

My old ICC version is from Dec. 2003. No AT90CAN128...I'll have to upgrade.

Your clean-ups will make future porting much easier.

Many thanks,
