How do you use GDB to debug GDB

[Stephen Smith]

I have a gdb debugger configured to for a remote target (host i686-pc-cygwin target=powerpc-motorola-elf).  normally I
run gdb as:

     powerpc-motorola-elf-gdb --command=C:/rti/bin/rtidbug.ini C:/examples/dll/main.exe

Now I want to run the gdb against the above process.  Since I am running this in a Windows NT command shell I can't use
    gdb   /usr/local/bin/powerpc-motorola-elf-gdb  some_process_id

Can someone help
