[lazarus] mwEdit issues

[Shane Miller]

Question. 
In mwCustomEdit, in the class definition for TMWEditList, it defines a procedure  (protected) called PUT that has an override declaration.  
In Delphi, this compiles fine, but under Linux, I get:
Erro: There is no method in an ancestor class to be overridded: TMWEDITLIST.PUT

TMWEditList is derived from TStringList and TStringList does NOT contain a PUT method. 

Why does it work in Delphi, but not in Linux.  Why does it work in Delphi at all?
