I have gdb-6.0 here and dont see how it does work, although
I would be really glad if baktrace would work. Compiling stuff

it would be -O2 if at all.
For m68k-linux it has the additional side effect of enforcing
a stricter interpretaion of our slightly unusual a0/d0/fp0 abi
so it wont be so good to have this as default.
