[fpc-pascal] Unexpected duplicate identifiers

[Mark Morgan Lloyd]

I've got a class that looks in part like this:

TTextStore= CLASS(TStringList)
             PRIVATE
               PROCEDURE NeverSort(sort: BOOLEAN);
             PUBLIC
               FUNCTION HereDocument(CONST name: STRING; VAR strings: 
TStringList): BOOLEAN;
               PROCEDURE Sort; OVERRIDE;

FPC 2.2.0 is giving me duplicate identifier errors for "sort" and 
"strings" above.

I've got nothing against going through the comparatively small amount of 
code affected but I'm a little mystified as to why this is happening: 
the rather elderly version of Delphi I'm using doesn't object, and I 
don't see why there should be a conflict between the class procedure and 
procedure parameter names.
