Yes, this is for dealing with Astudio 4.10...

I looked at the GCC output for compiling a C module to asm and it appears
the C compiler puts lots and lots of debug info into the assembly to support
dwarf-2.  So it appears I am outta luck.  I'll need to wrap my assembly
stuff in C...  which means I'll need to re-read the section on clobbers and
temps, etc.  Sigh.

Maybe coff wasn't so bad.  At least the assembler could deal with it via

Which debugger? I'm assuming you mean AVR Studio? Because AFAIK, AVR
Studio 4.10 requires DWARF2 debugging information, but the AVR port of
GDB requires stabs. And AFAIK, the avr-libc docs won't have anything
about DWARF2 because of GDB, and because this is a recent change. Have
you checked the binutils/gcc docs?
