	* frame.c (get_frame_id): If the frame's ID isn't valid, get it.

-	this is faster.
-
-Sun Oct  4 22:35:47 1998  Martin M. Hunt  <hunt@cygnus.com>
-

-
-	* Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &

-	result_ptr structure.  See the comments in gdbtk.h for more
-	details.

-	shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c

-	(gdbtk_test): New function called by main when the --tclcommand
-	option is used.

-        (gdb_get_trace_frame_num): new function to get the

-        (struct wrapped_call_objs): Change the `func' member to
-        be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector

-        since that's what all the users of this structure seem to expect.
-        (call_obj_wrapper): Cast clientData properly before storing it in

-
-	* gdbtk.c (struct wrapped_call_objs): Change the `func' member to
- 	be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector

- 	since that's what all the users of this structure seem to expect.
-	(call_obj_wrapper): Cast clientData properly before storing it in
-	the wrapped_args structure.
