On a UNIX system, you would first start a native GDB, and then use it
to run and debug the child GDB.

        $ gdb /usr/local/bin/powerpc-motorola-elf-gdb
        GDB is free software and you are ...
        (gdb)

At this point, I typically install breakpoints where I think there the
problem lies.  The .gdbinit file distributed with GDB sets breakpoints
and sets directory paths, etc.; thus creating an initial environment
that are likely to be useful debugging GDB.

Then run your child GDB.

        (gdb) run --command=C:/rti/bin/rtidbug.ini C:/examples/dll/main.exe

I don't have experience with NT to know whether this will work there.
