	only ever using the Project field.

2009-04-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Do not set
	Body_Required on the generated compilation node. The new node is linked
	to its body, but both share the same file, so we do not set this flag
	on the new unit so as not to create a spurious dependency on a
	non-existent body in the ali file for the instance.

	* prj.adb, prj.ads, prj-nmsc.adb (Check_File, Record_Ada_Source,
	Add_Source): merge some code between those. In particular change where
	file normalization is done to avoid a few extra calls to
	Canonicalize_File_Name. This also removes the need for passing
	Current_Dir in a number of subprograms.

	* lib-load.adb (Make_Instance_Unit): In the case where In_Main is
	False, assign the correct unit to the Cunit field of the new table
	entry. We want the spec unit, not the body unit.

	* rtsfind.adb (Make_Unit_Name, Maybe_Add_With): Simplify calling
	interface for these.
	(Maybe_Add_With): Check whether we're trying to a with on the current
	unit, and avoid creating such directly self-referential with clauses.
	(Text_IO_Kludge): Add implicit with's for the generic pseudo-children of
	[[Wide_]Wide_]Text_IO. These are needed for Walk_Library_Items,
	and matches existing comments in the spec.

	* sem.adb (Walk_Library_Items): Add various special cases to make the

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Use Body_Cunit
	instead of Parent (N), for uniformity.

	* prj-proc.adb, prj-nmsc.adb (Find_Ada_Sources,
	Get_Path_Name_And_Record_Ada_Sources): merged, since these were
	basically doing the same work (for explicit or implicit sources).
	(Find_Explicit_Sources): renamed to Find_Sources to better reflect its
	role. Rewritten to share some code (testing that all explicit sources
	have been found) between ada_only and multi_language modes.

2009-04-24  Jerome Lambourg  <lambourg@adacore.com>

	* sem_prag.adb (Check_Form_Of_Interface_Name): Allow space in Ext_Name

	clean.adb, prj-nmsc.adb, prj-env.adb, prj-env.ads (Project_Data.Seen):
	field removed. This is not a property of the
	project, just a boolean used to traverse the project tree, and storing
	it in the structure prevents doing multiple traversal in parallel.
	(Project_Data.Checked): also removed, since it was playing the same role
	as Seen when we had two nested loops, and this is no longer necessary
	(For_All_Imported_Projects): removed, since in fact there was already
	the equivalent in For_Every_Project_Imported. The latter was rewritten
	to use a local hash table instead of Project_Data.Seen
	Various loops were rewritten to use For_Every_Project_Imported, thus
	removing the need for Project_Data.Seen. This avoids a lot of code
	duplication

2009-04-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Actuals): Do not create blocks around code
	statements, even though the actual of the call is a concatenation,
	because the argument is static, and we want to preserve warning
	messages  about sequences of code statements that are not marked
	volatile.

	* sem_warn.adb: remove obsolete comment about warning being obsolete

	* s-tasren.adb (Task_Do_Or_Queue): If a timed entry call is being
	requeued and the delay has expired while within the accept statement
	that executes the requeue, do not perform the requeue and indicate that
	the timed call has been aborted.

	a table. This makes the list somewhat more obvious, but more importantly
	removes the need to pass a pointer to the project_tree_data in a few
