Compilando Ares <Error>

[Mav]

Sigo tratando de resolver los múltiples errores de compilación que me da el Ares,
estoy parado aquí ahora....no lo encuentro..????

Código Delphi [-]
function estrai_path_da_lnk(filen:widestring):widestring;
var
  AnObj: IUnknown;
  ShLink: IShellLinkW;
  PFile: IPersistFile;
  Data: TWin32FindData;
  Buffer: array [0..255] of widechar;
begin
result:='';
try
  AnObj := CreateComObject(CLSID_ShellLink);
  ShLink := AnObj as IShellLinkW;
  PFile := AnObj as IPersistFile;

  PFile.Load(PWChar(FileN), STGM_READ);


  ShLink.GetPath(Buffer, Sizeof(Buffer), Data, SLGP_UNCPRIORITY);
  result := Buffer;

 except
 end;
end;

En esta linea es donde dá el siguiente error:
ShLink.GetPath(Buffer, Sizeof(Buffer), Data, SLGP_UNCPRIORITY);

[DCC Error] helper_urls.pas(153): E2033 Types of actual and formal var parameters must be identical

En ShlObj.pas:

Código Delphi [-]
IShellLinkW = interface(IUnknown) { sl }
    [SID_IShellLinkW]
    function GetPath(pszFile: PWideChar; cchMaxPath: Integer;
      var pfd: TWin32FindDataW; fFlags: DWORD): HResult; stdcall;

De la "Guia de Referencia de Delphi":

(E2033)Types of actual and formal var parameters must be identical:
For a variable parameter, the actual argument must be of the exact type of the formal parameter.

Código Delphi [-]
program Produce;
procedure SwapBytes(var B1, B2: Byte);
var
Temp: Byte;
begin
Temp := B1; B1 := B2; B2 := Temp;
end;
var
C1, C2: 0..255; (*Similar to a byte, but NOT identical*)
begin
SwapBytes(C1,C2); (*<-- Error message here*)
end.

Arguments C1 and C2 are not acceptable to SwapBytes, although they have the exact memory representation and range that a
Byte has.

Código Delphi [-]
program Solve;
procedure SwapBytes(var B1, B2: Byte);
var
Temp: Byte;
begin
Temp := B1; B1 := B2; B2 := Temp;
end;
var
C1, C2: Byte;
begin
SwapBytes(C1,C2); (*<-- No error message here*)
end.

So you actually have to declare C1 and C2 as Bytes to make this example compile.
He realizado varias pruebas, pero, no lo pillo....
¿Alguna idea? Por supuesto gracias de antemano...
