	* 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
