It's questionable whether the elfcoff patch will continue. Eventually we 
would like for it to go away. AVR Studio, for GCC, is moving towards 
using ELF and DWARF2. AVR GDB apparently can use DWARF2. I know of one 
commercial simulator that has just written in support for DWARF2, and 
another commercial simulator that is planning for DWARF2 support. Yet, 
it's somewhat troubling that there are these bug reports for DWARF2 
support in AVR GCC.

Perhaps Atmel can comment on whether they think it would be prudent to 
continue the ELFCOFF convertor in the toolset until these problems can 
get worked out?

No. Last I checked, Joerg said he doesn't have the time to update it. I 
might have some time later on, but it's questionable.
