downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective

+	which limits the number of system calls in some cases.
+	* osint.ads, prj.ads (Source_Data): do not store directly the timestamp,
+	but the file attributes since we also need access to the size of the
+	ALI file to parse it. This gives an opportunity for saving system calls
+	on Unix systems.

+
+	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): When creating a

+	the implicit with clause for List_Controller occurs on the package spec.
+
+	* rtsfind.adb (Text_IO_Kludge): Fine tune the creation of implicit

+	particular, avoid cycles, such as Ada.Wide_Text_IO.Integer_IO and
+	Ada.Text_IO.Integer_IO both with-ing each other.
+
+	* sem.adb (Walk_Library_Items): Suppress assertion failure in certain
+	oddball cases when pragma Extend_System is used.
+
+	* sem_ch12.adb (Get_Associated_Node): Prevent direct 'with' cycles in
+	the case where a package spec instantiates a generic whose body with's
+	this package, so Walk_Library_Items won't complain about cyclic with's.

+	(Project_Id): now a real pointer to Project_Data, instead of an index

+
+2009-04-29  Nicolas Setton  <setton@adacore.com>

+
+2009-04-24  Ed Schonberg  <schonberg@adacore.com>
+
+	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Do not set

+	on the new unit so as not to create a spurious dependency on a

+	Current_Dir in a number of subprograms.
+
+2009-04-24  Bob Duff  <duff@adacore.com>
+
+	* lib-load.adb (Make_Instance_Unit): In the case where In_Main is

+
+	* rtsfind.adb (Make_Unit_Name, Maybe_Add_With): Simplify calling

+	(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

+
+	* prj-proc.adb, prj-nmsc.adb (Find_Ada_Sources,

+	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>
+

+

+	field removed. This is not a property of the
+	project, just a boolean used to traverse the project tree, and storing

+	(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

+
+2009-04-24  Ed Schonberg  <schonberg@adacore.com>
+
+	* sem_res.adb (Resolve_Actuals): Do not create blocks around code

+	be able to call Set_Mapping_File_Initial_State_To_Empty with it.
+
+	* prj.adb (Initialize): Do not call Prj.Env.Initialize
+	(Reset): Do not call Prj.Env.Initialize. Instead, initialize the new

+
+	* prj.ads (Private_Project_Tree_Data): new components moved from

+	Ada_Prj_Objects_File_Set, Fill_Mapping_File.

+
+	* prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb

+
+2009-04-24  Emmanuel Briot  <briot@adacore.com>
+

+	(Source_Iterator): new type.

+	that the field with that name is no longer used
+	(Project_Data.Languages): removed, no longer used, and duplicates
+	information already available through First_Language_Processing.
+	(Prj.Language_Index): now an actual pointer, instead of an index into
+	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
+	places, and makes accessing the attributes of a languages more
