PDP11 unixes use much older debug formats, and DEC operating systems are more primitive still (no debug symbols at all, of any kind). So for that case at least, supporting the target but without debug symbols would not be a crazy option. Of course, it would be neat to be able to debug PDP-11 code with GDB... paul
