	* a-taside.ads, a-taside.adb:
	Remove some dependencies, to make it easier to make this unit truly
	Preelaborate.
	Rewrite some code to be conformant with Preelaborate rules.

	* g-os_lib.adb: Remove non-preelaborate code so that this unit can be
	marked Preelaborate in the future.

	* s-proinf.ads, g-string.ads, s-auxdec.ads, s-auxdec-vms_64.ads: Make
	these units Preelaborate.

	* s-exctab.adb: Update use of Except.Id.Full_Name.

	* s-soflin.ads, s-soflin.adb: Mark this unit Preelaborate_05.
	(Set_Exc_Stack_Addr_Soft, Get_Exc_Stack_Addr_NT, Set_Exc_Stack_Addr_NT,

	Remove reference to *Machine_State_Addr*, no longer needed.

	* s-stalib.ads: Mark this unit as Preelaborate[_05].

	obey Preelaborate rules.

	* s-tassta.adb (Finalize_Global_Tasks): Remove Get/Set_Exc_Stack_Addr
	soft links, no longer used.

	* s-traces.ads, s-traent.ads: Add pragma Preelaborate, since these
	packages are suitable for this categorization.

	* s-solita.adb: Replace use of Ada.Exception by raise xxx with "..."
	since we compile run-time sources in Ada 2005 mode.
	(Timed_Delay_T): Call Abort_Defer/Undefer around Timed_Delay, to
	avoid having s-taprop*.adb depend on s-soflin and to avoid code
	duplication.
