Under FPC 2.4.2 I have been using RBTree unit that uses generics. With
2.6.0 it fails to compile. I know that there have been changes for 2.6.0
but I have checked the syntax in the 2.6.0 Language Reference and cannot
see why the error is occurring. I have also looked in Mantis but don't
know if anything there relates to my problem. I have excerpted the code
below and attached the complete unit.
==================
unit FOS_REDBLACKTREE_GEN;
// (c) Copyright FirmOS Business Solutions GmbH
// Author Helmut Hartl, Franz Schober
}
//{$MODE OBJFPC}
{$MODE DELPHI}
{$H+}
interface
type
TRB_NodeColor=(R,B);
{ TGFOS_RBTree }
{$B-}
generic TGFOS_RBTree<_TKey,_TStore> = class(TInterfacedObject)
*** The error occurs at the line above.

TGUndefinedKey = function :_TKey;
TGFOS_RB_OnItem = procedure (const Item:_TStore) of object;
TGFOS_RB_OnItemN = procedure (const Item:_TStore);
==================
Thanks for any help.
