The warnings can be ignored, they do no harm.

This maillinglist drops attachments. You could send them directly to
me, but I don't have access to a real atmega128, so I cannot test them.

You may double check that you really use the usart0 port. When I got
my first atmega128 style controller board, I connected the usart1 and
programmed usart0. Took a few hours to find out and another one to roll
back the changes I made... :=(
