+
+--  This is the HP version of this package
+
+--  This package defines some system dependent parameters for GNAT. These
+--  are values that are referenced by the runtime library and are therefore
+--  relevant to the target machine.
+
+--  The parameters whose value is defined in the spec are not generally
+--  expected to be changed. If they are changed, it will be necessary to
+--  recompile the run-time library.
+
+--  The parameters which are defined by functions can be changed by modifying
+--  the body of System.Parameters in file s-parame.adb. A change to this body
+--  requires only rebinding and relinking of the application.
+
+--  Note: do not introduce any pragma Inline statements into this unit, since
+--  otherwise the relinking and rebinding capability would be deactivated.

+   -- Tasking Profile --
+   ---------------------
+
+   --  In the following sections, constant parameters are defined to
+   --  allow some optimizations and fine tuning within the tasking run time
+   --  based on restrictions on the tasking features.
+
+   ----------------------
+   -- Locking Strategy --
+   ----------------------
+
+   Single_Lock : constant Boolean := False;
+   --  Indicates whether a single lock should be used within the tasking
+   --  run-time to protect internal structures. If True, a single lock
+   --  will be used, meaning less locking/unlocking operations, but also
+   --  more global contention. In general, Single_Lock should be set to
+   --  True on single processor machines, and to False to multi-processor
+   --  systems, but this can vary from application to application and also
+   --  depends on the scheduling policy.
+
+   -------------------
+   -- Task Abortion --
+   -------------------
+
+   No_Abort : constant Boolean := False;
+   --  This constant indicates whether abort statements and asynchronous
+   --  transfer of control (ATC) are disallowed. If set to True, it is
+   --  assumed that neither construct is used, and the run time does not
+   --  need to defer/undefer abort and check for pending actions at
+   --  completion points. A value of True for No_Abort corresponds to:
+   --  pragma Restrictions (No_Abort_Statements);
+   --  pragma Restrictions (Max_Asynchronous_Select_Nesting => 0);
+
+   ---------------------
+   -- Task Attributes --
+   ---------------------
+
+   Max_Attribute_Count : constant := 32;
+   --  Number of task attributes stored in the task control block
+
+   -----------------------
+   -- Task Image Length --
+   -----------------------
+
+   Max_Task_Image_Length : constant := 256;
+   --  This constant specifies the maximum length of a task's image
+
+   ------------------------------
+   -- Exception Message Length --
+   ------------------------------
+
+   Default_Exception_Msg_Max_Length : constant := 200;
+   --  This constant specifies the default number of characters to allow
+   --  in an exception message (200 is minimum required by RM 11.4.1(18)).
