+      # /usr/include/stdio.h:351: error: previous declaration of ‘setlinebuf’ was here
+      #
+      # My patch fixes this by changing the declared return type of setlinebuf in
+      # gnushogi.h to int to match up with stdio.h's declaration
+      # It was returning void anyway, so unless something errantly relies on it not
+      # leaving something in the return register, this shouldn't break anything
