SetAutoSubClass() has been deprecated in newer versions of Delphi. Can anyone tell me what to replace it with ? I cannot find it in the Delphi 2009 OLH, nor in the VCL source (Forms).

I've been able to find the D5 source code and saw that it was obsolete there too. The function implementation is empty. Does anybody have an idea where this function originated from ? Although I'm fairly sure I can remove the call, I would like to know what it was intended for.
