(defadvice gdb (before debug-visited-file activate)
  "When called interactively, provide the visited file name as a default 
argument."
  (interactive (list (gud-query-cmdline 'gdb
                                        (if buffer-file-name
                                            (file-name-nondirectory
                                             buffer-file-name))))))

(let ((gud-buffer-name-regexp "\\*gud-.*\\*\\(\\|<[0-9]+>\\)"))
 (setq special-display-buffer-regexps
       (cons gud-buffer-name-regexp special-display-buffer-regexps))
 (setq same-window-regexps
       (delete gud-buffer-name-regexp same-window-regexps)))

That's a bad idea, because C-x is a prefix character.

Try customizing the gud-key-prefix variable.
