	* gnatcmd.adb (Get_Closure): Do not crash when it is not possible to
	delete or close the file when the call to gnatmake was successful.

2011-08-05  Yannick Moy  <moy@adacore.com>

	* gnat1drv.adb (Adjust_Global_Switches): in ALFA mode, set
	Global_Discard_Names.

2011-08-05  Ed Schonberg  <schonberg@adacore.com>

	* sinfo.ads: comments on use of entity field for aspect specifications.

2011-08-05  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Reset_Entity): If the entity field of the associated
	node is not itself an entity but a selected component, it is a
	rewritten parameterless call to an en enclosing synchronized operation,
	and this expansion will be performed again in the instance, so there is
	no global information to preserve.
