	* freeze.adb (Freeze_All_Ent): An incomplete type is not
	frozen by a subprogram body that does not come from source.

2011-11-23  Pascal Obry  <obry@adacore.com>

	* s-oscons-tmplt.c: Add PTY_Library constant. It contains
	the library for pseudo terminal support.
	* g-exptty.ads: Add pseudo-terminal library into a Linker_Options
	pragma.

2011-11-23  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch9.adb: No check on entry family index if generic.

2011-11-23  Thomas Quinot  <quinot@adacore.com>

	* sem_ch9.adb, s-taprop.ads, s-taprop-hpux-dce.adb, s-taprop-irix.adb,
	s-taprop-posix.adb, s-taprop-rtx.adb, s-taprop-solaris.adb,
	s-taprop-tru64.adb, s-taprop-vxworks.adb: Move dependency on
	System.OS_Constants from shared spec of
	System.Tasking.Primitive_Operations to the specific body variants
	that really require this dependency.

2011-11-23  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Analyze_Subprogram_Renaming_Declaration):
	If the declaration has aspects, analyze them so they can be
	properly rejected.

2011-11-23  Hristian Kirtchev  <kirtchev@adacore.com>

	* a-comutr.adb, a-coorma.adb, a-coorse.adb, a-convec.adb, a-cihase.adb,
	a-cimutr.adb, a-coinve.adb, a-ciorma.adb, a-ciorse.adb, a-cobove.adb,
	a-cohama.adb, a-cihama.adb, a-cidlli.adb, a-cdlili.adb, a-cbhama.adb,
	a-cbhase.adb, a-cbmutr.adb, a-cborma.adb, a-cborse.adb, a-cbdlli.adb:
	Add with and use clause for Ada.Finalization. Type
	Iterator and Child_Iterator are now derived from Limited_Controlled.
	(Finalize): New routine.
	(Iterate): Add a renaming of counter Busy and
	increment it. Update the return aggregate.
	(Iterate_Children): Add a renaming of
	counter Busy and increment it. Update the return aggregate.
	(Iterate_Subtree): Add a renaming of counter Busy and increment
	it. Update the return aggregate.
	* a-cdlili.ads, a-cidlli.ads: Type List_Access is now a general access
	type.
	* a-cihama.ads: Type Map_Access is now a general access type.
	* a-comutr.ads, a-cimutr.ads: Use type Natural for the two locks
	associated with the tree.
	* a-cohama.ads: Type Map_Access is now a general access type.
	* a-coinve.ads, a-convec.ads: Type Vector_Access is now a general
	access type.
	* exp_ch5.adb (Expand_Iterator_Loop): Do not create a block
	to wrap the loop as this is done at an earlier step, during
	analysis. The declarations of the iterator and the cursor use
	the usual Insert_Action mechanism when added into the tree.
	* sem_ch5.adb (Analyze_Loop_Statement): Remove local constant
	Loop_Statement and replace all respective uses by N. Add local
	constant Loc. Preanalyze the loop iterator to discover whether
	it is a container iterator and if it is, wrap the loop in a
	block. This ensures that any controlled temporaries produced
	by the iteration scheme share the same lifetime of the loop.
	(Is_Container_Iterator): New routine.
	(Is_Wrapped_In_Block): New routine.
	(Pre_Analyze_Range): Move spec and body to the library level.

2011-11-23  Sergey Rybin  <rybin@adacore.com frybin>

	* gnat_ugn.texi, vms_data.ads: Add documentation for new gnatpp option
	that controls casing of type and subtype names.

2011-11-23  Yannick Moy  <moy@adacore.com>

	* sem_ch3.adb: Minor addition of comments.

2011-11-23  Thomas Quinot  <quinot@adacore.com>

	* prj-part.adb (Extension_Withs): New global variable,
	contains the head of the list of WITH clauses from the EXTENDS
	ALL projects for which virtual packages are being created.
	(Look_For_Virtual_Projects_For): When recursing through
	an EXTENDS ALL, add the WITH clauses of the extending
	project to Extension_Withs.  When adding a project to the
	Virtual_Hash, record the associated Extension_Withs list.
	(Create_Virtual_Extending_Project): Add a copy of the appropriate
	Extension_Withs to the virtual project.

2011-11-23  Thomas Quinot  <quinot@adacore.com>

	* mlib-tgt-specific-vxworks.adb: Minor reformatting.

2011-11-23  Thomas Quinot  <quinot@adacore.com>

	* Make-generated.in (Sdefault.Target_Name): Set to
	$(target_noncanonical) instead of $(target) for consistency.
