[fpc-pascal] Forward type not resolved

[Leonardo M. Ramé]

Hi, I'm trying to create a forward declaration for a class, as I use to do in Delphi, but I'm getting "Forward type not resolved". How can I troubleshoot this?.

Here's the code:

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils; 

type
  TQuote = class; // forward declaration.

  TOnSqueeze = procedure (AQuote: TQuote); of object;

  { TQuote }

  TQuote = class(TCollectionItem)
  private
    FAdjClose: Double;
    FBBand_Diff: Double;
  ...

And, this is the error I'm getting:

quote.pas(11,12) Error: Forward type not resolved "TQuote"
