Yes, that's true.  I'm going to need gdbserver to work in the

slip past 5.1 (and at this stage it seems inevitable).  Especially
since no one seems to be concerned with gdbserver having broken.

I didn't mean something sent over the wire; I meant a source file that
could be linked into both gdb and gdbserver.
