The deprecated_interactive_hook is currently setup to point to an
empty function.  Removing this will allow a small clean up in GDB.
The empty function used by deprecated_interactive_hook currently looks
like this:

    /* Come here during long calculations to check for GUI events.  Usually invoked
       via the QUIT macro.  */

    void
    gdbtk_interactive (void)
    {
      /* Tk_DoOneEvent (TK_DONT_WAIT|TK_IDLE_EVENTS); */
    }

As far as I can tell this function has been empty for years.  If in
the future we do ever want or need to implement something like
gdbtk_interactive, then we would be better off adding a new observable
to GDB, but I don't see a reason to add one at this point just so that
gdbtk can call an empty function.

ChangeLog:

	* gdbtk/generic/gdbtk-hooks.c (gdbtk_add_hooks): Don't setup
	deprecated_interactive_hook.
	* gdbtk/generic/gdbtk.c (gdbtk_interactive): Delete.
	* gdbtk/generic/gdbtk.h (gdbtk_interactive): Delete declaration.

Wowser, how time flies when you're working on a release!

I would approve this, but it appears that Patrick has already adjusted the code
based on the related patch getting into gdb:

commit d8772263cdb55564e93528cf16248d3479d23346 (HEAD -> master, origin/master, origin/HEAD)
Author: Patrick Monnerat <patrick@monnerat.net>
Date:   Thu Jun 20 14:58:09 2019 +0200

    Upgrade submodule, sync code.
    
    deprecated_interactive hook has disappeared: remove its (noop) use.
    
    * gdbtk/generic/gdbtk-hooks.c (gdbtk_add_hooks): remove setting of
      deprecated_interactive_hook.
    * gdbtk/generic/gdbtk.[ch] (gdbtk_interactive): remove.

I appreciate that you took the time to take a look, and, of course, thanks for
the patch.

Keith
