Apologies, I got the filenames wrong in the above changelog entry.  I've
committed the following patch to fix them.

Once again, sorry for the mistake.

It looks like deprecated_command_loop_hook is used in gdbtk just like
it's used in the MI code.  I've submitted a patch to gdbtk that removes
the use:
  http://sourceware.org/ml/insight/2013-q3/msg00029.html

Thanks,
Andrew

FYI, this hook is essential to gdbtk, which uses it to connect into its
main command loop.  It's not obvious to me whether it would be easy or
hard to rewrite gdbtk to not need it.
