[avr-libc-dev] can't define my own __do_copy_data() for atmega128

Hi List.

I'm able to define __do_copy_data() as an empty function when compiling for an atmega64: it's useful when chasing the last available bytes in a bootloader when you have nothing in .data. Now I can't do the same thing with the atmega128: the linker complains that the function is already defined in gcrt1.S.

I use avr-gcc 3.4.4 and avr-libc 1.4.0

Any hint welcome.
