I reverted the changes by Michael and changed the parameters of those functions to constref instead. However that doesn't mean that there won't be breaking changes: there are some interfaces that take REFIID (or TGuid parameters that are generally used with interface IIDs) and those will need to be changed as well. Most will be interface which have implementations provided by e.g. Windows, but in some cases those might be implemented by users and thus will lead to compilation failures (but at least those will be easy to spot :) ).
