Hi,

I am using the current version of the Win32 binary avr-gcc on 
www.avrfreaks.net to compile code for the ATMega128. I had to 
assemble a correct version of gcrt1.s for the ATMega128. I then 
had to modify the ATMega103 linker script to correctly define the 
ATMega128 memory areas. I also modified the iomacros.h file to 
update the inp and outp macros, so that they work correctly on the 
ATMega128.
With this setup I have succefully generated code for the 
ATMega128. I have run the code on an actual ATMega128 - Not 
just simulated it.

If you need more detail, or copies of the modified files then I can 
email them.

Regards
