targparm.ads, [...] (Targparm_Tags): Add PAS value corresponding to the Preallocated_Stacks flags in System. 

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

	* targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
	corresponding to the Preallocated_Stacks flags in System.
	(Get_Target_Parameters): Including the processing for
	Preallocated_Stacks.

	* system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
	system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,
	system-freebsd-x86.ads, system-lynxos-ppc.ads, system-lynxos-x86.ads,

	system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
	system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
	used to signal whether the compiler creates the required stacks and
	descriptors for the different tasks (when True) or it is done by the
	underlying operating system at run time (when False).
	It is initially set to False in all targets.

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
	if it is supported by the target.
	(Make_Task_Create_Call): Pass the stack address if it has been
	previously created. Otherwise pass a Null_Address.

	* snames.adb: Add _stack.

	* snames.ads: Add Name_uStack. Required to allow the expander to
	statically allocated task stacks.

	* s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
	Stack_Address argument.
	Check that its value is equal to Null_Address because this target does
	not support the static stack allocation.
