Thanks.  A few remarks.  Please try to ident as

         (setq gdb-source-window-list
               (cl-remove-duplicates
                (cl-remove-if-not
		(lambda (win)
		  (and (window-live-p win)
                        (equal (window-frame win)
                               (selected-frame))))
                 gdb-source-window-list)
                :test #'equal))

so we can safely change this later and easily stay within our line
length limits.  Also, tests like

                        (equal (window-frame win)
                               (selected-frame))))

should use "eq" instead of "equal" and ones like

                      ((member (selected-window) gdb-source-window-list) 'source)))

"memq" instead of "member".

Similarly to the above, writing

	 (window
	  (when buffer
	    (if (eq gud-minor-mode 'gdbmi)
                 (gdb-display-source-buffer buffer)
               ;; Gud still has the old behavior.
               (or (get-buffer-window buffer)
                   (display-buffer buffer '(nil (inhibit-same-window . t)))))))

permits us to stay within the 80 columns limit.

Finally, instead of "Also, we simply the logic ..." I'd write "Also,
simplify the logic ...".  And please provide a NEWS entry.

Thanks again for the work, martin
