Hmm. Doesn't the sim need something like a "-msim" option (or a simulator 
linker script or a special specs file)? Does the simulator support the 
403? It may just be a generic insn set simulator.

Try "-msim". Try looking for a linker script (like sim.ld) in the install 
dir of the compiler. I'm sure one of these is needed.

If this fails, I suggest asking on gdb@sources.redhat.com about how to 
build and debug something on the PPC simulator. The real experts hang out 
there.
