Yes, I was aware that VMLab is still using the COFF format. I've heard 
that they will probably be using it for some time. :-(
The OP didn't say whether he was using VMLab or AVR Studio as their 
debugger.

I can't remember offhand how to tell gas to generate DWARF2 debug info; 
there might be some information on the avr-gcc-list about it if you want 
to search the archives. It *may* be that there isn't currently a way, 
but like I said, I can't clearly remember.

And please don't send me personal replies (unless its something 
personal); please use "Reply All" in your email client and reply to the 
list as well. Thanks. I went ahead and sent this to the avr-gcc list too.
