IIRC, the OP's output showed the assembler step with -gstabs and the C 
compiler had -gdwarf-2. (I don't have the output handy at the moment to 
verify.) Perhaps this is the problem?

This is also complicated by the fact that GCC wants "-gdwarf-2" and gas 
wants "-gdwarf2" (minus the hyphen). So some hand-editing of the 
makefile I think would be necessary.

But I still don't know if changing that would be sufficient to solve the 
problem. It would be nice if somebody could experiment and find out if 
this is all that is needed to fix this.

Joerg, interestingly Colin tested using GDB with DWARF2 and so far 
everything seems to work (on C code for the AVR). FYI, I'm setting up 
the makefile template to default to DWARF2..... but we can discuss that 
off-list.
