Converting program from Delphi 3 to Delphi 4 errors

I'm in the process of converting my program from Delphi 3 to 4.  While trying to compile this program in Delphi 4, a few error messages occured.  The messages are :-
(error) Declaration of 'QueryInterface' differs from declaration in interface 'ISimpleFrameSite'.

(error) Declaration of 'QueryInterface' differs from declaration in interface 'IPropertyNotifySink'.

Please HELP. Thank you.
