	* sem_prag.adb (Analyze_Pragma, case Elaborate): Forbid pragma
	Elaborate in SPARK mode.

2014-11-20  Bob Duff  <duff@adacore.com>

	* s-taskin.adb, s-tassta.adb (Initialize_ATCB): If Domain
	is null, then initialize T.Common.Domain to that of the
	activating task (not the parent task!), as required by RM-D.16.1.
	T.Common.Domain should never be null; so Assert. Remove similar
	code from Create_Task in s-tassta.adb.
	* s-mudido-affinity.adb: Remove checks for Domain = null,
	because it can't be null.
	* s-taskin.ads, s-taspri-dummy.ads, s-taspri-mingw.ads,
	s-taspri-posix.ads, s-taspri-posix-noaltstack.ads,
	s-taspri-solaris.ads, s-taspri-vxworks.ads: Mark limited types as
	explicitly limited for clarity.
