The removed preprocessor macro's refer to types that are not defined in the file anymore; the only other place where shared_guard is defined is in winobj.h, which also defines the same macro's. Therefore, this change is safe. (Side note is that these macro's weren't used at all anyway, but that is orthogonal to the issue.)
