It should be safe to remove the offending lines, but there will probably be other issues after that. AC uses #if !UNITY_5 in other parts of the code as well, so I guess you'll have to deal with that t

#if UNITY_5 { }

#if UNITY_5_4_OR_NEWER

#if UNITY_EDITOR

#if UNITY_EDITOR

ShowGUI() needs to be inside a #if UNITY_EDITOR block, as it's only available when running in the editor, not in final builds.

The ShowGUI() function requires UnityEditor's namespace, but the Action class itself cannot live in an Editor folder - meaning any reference to UnityEditor and it's API must live inside #if UNITY_EDIT

#if UNITY_EDITOR

#if UNITY_EDITOR                shouldShowCursor = true;#endif
