An error has occurred while loading `/home/kirina/.emacs':

Symbol's function definition is void: gdb-many-windows

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
