+--  This package contains the definitions and routines associated with the
+--  implementation and use of the Task_Info pragma. It is specialized
+--  appropriately for targets that make use of this pragma.
+
+--  Note: the compiler generates direct calls to this interface, via Rtsfind.
+--  Any changes to this interface may require corresponding compiler changes.
+
+--  The functionality in this unit is now provided by the predefined package
+--  System.Multiprocessors and the CPU aspect. This package is obsolescent.
+
+--  This is the Windows (native) version of this module
+
+with System.Win32;
+
+package System.Task_Info is
+   pragma Obsolescent (Task_Info, "use System.Multiprocessors and CPU aspect");
+   pragma Preelaborate;
+   pragma Elaborate_Body;
+   --  To ensure that a body is allowed
+
+   use type System.Win32.ProcessorId;
+
+   --  Windows provides a way to define the ideal processor to use for a given
+   --  thread. The ideal processor is not necessarily the one that will be used
+   --  by the OS but the OS will always try to schedule this thread to the
+   --  specified processor if it is available.
+
+   --  The Task_Info pragma:
+
+   --    pragma Task_Info (EXPRESSION);
+
+   --  allows the specification on a task by task basis of a value of type
+   --  System.Task_Info.Task_Info_Type to be passed to a task when it is
+   --  created. The specification of this type, and the effect on the task
+   --  that is created is target dependent.
+
+   --  The Task_Info pragma appears within a task definition (compare the
+   --  definition and implementation of pragma Priority). If no such pragma
+   --  appears, then the value Unspecified_Task_Info is passed. If a pragma
+   --  is present, then it supplies an alternative value. If the argument of
+   --  the pragma is a discriminant reference, then the value can be set on
+   --  a task by task basis by supplying the appropriate discriminant value.
+
+   --  Note that this means that the type used for Task_Info_Type must be
+   --  suitable for use as a discriminant (i.e. a scalar or access type).
