I'm not sure about that.  Remember, our DWARF-2 support is still
"accidental" (or incidental), it's only a by-product of other GCC
platforms moving to DWARF-2, e.g. avr-as' support of --gdwarf-2 is
disfunctional, and AVR-GDB cannot usefully handle DWARF-2 at all.

The stabs support in AVR-GDB to decode stack frames has once been
written by Ted Roth.  I don't know whether he also had to
tune/enable/tweak anything in GCC for this to work.
