Subject: [PATCH] 2003-11-13  Vincent Celier  <celier@gnat.com>

	* 5bml-tgt.adb (Build_Dynamic_Library): Use
	Osint.Include_Dir_Default_Prefix instead of
	Sdefault.Include_Dir_Default_Name.

	* gnatlbr.adb: Update Copyright notice
	(Gnatlbr): : Use Osint.Include_Dir_Default_Prefix instead of
	Sdefault.Include_Dir_Default_Name and Osint.Object_Dir_Default_Prefix
	instead of Sdefault.Object_Dir_Default_Name

	* gnatlink.adb:
	(Process_Binder_File): Never suppress the option following -Xlinker

	* mdll-utl.adb:
	(Gcc): Use Osint.Object_Dir_Default_Prefix instead of
	Sdefault.Object_Dir_Default_Name.

	* osint.ads, osint.adb:
	(Include_Dir_Default_Prefix, Object_Dir_Default_Prefix): New functions
	Minor reformatting.

	* vms_conv.ads: Minor reformating
	Remove GNAT STANDARD and GNAT PSTA

	* vms_conv.adb:
	Allow GNAT MAKE to have several files on the command line.
	(Init_Object_Dirs): Use Osint.Object_Dir_Default_Prefix instead of
	Sdefault.Object_Dir_Default_Name.
	Minor Reformating
	Remove data for GNAT STANDARD

	* vms_data.ads:
	Add new compiler qualifier /PRINT_STANDARD (-gnatS)
	Remove data for GNAT STANDARD
	Remove options and documentation for -gnatwb/-gnatwB: these warning
	options no longer exist.

2003-11-13  Ed Falis  <falis@gnat.com>

	* 5zthrini.adb: (Init_RTS): Made visible

	* 5zthrini.adb:
	(Register): Removed unnecessary call to taskVarGet that checked whether
	 an ATSD was already set as a task var for the argument thread.

	* s-thread.adb:
	Updated comment to reflect that this is a VxWorks version
	Added context clause for System.Threads.Initialization
	Added call to System.Threads.Initialization.Init_RTS

2003-11-13  Jerome Guitton  <guitton@act-europe.fr>

	* 5zthrini.adb:
	(Init_RTS): New procedure, for the initialization of the run-time lib.

	* s-thread.adb:
	Remove dependancy on System.Init, so that this file can be used in the
	AE653 sequential run-time lib.

2003-11-13  Robert Dewar  <dewar@gnat.com>

	* bindgen.adb: Minor reformatting

2003-11-13  Ed Schonberg  <schonberg@gnat.com>

	* checks.adb:
	(Apply_Discriminant_Check): Do no apply check if target type is derived
	from source type with no applicable constraint.

	* lib-writ.adb:
	(Ensure_System_Dependency): Do not apply the style checks that may have
	been specified for the main unit.

	* sem_ch8.adb:
	(Find_Selected_Component): Further improvement in error message, with
	RM reference.

	* sem_res.adb:
	(Resolve): Handle properly the case of an illegal overloaded protected
	procedure.

2003-11-13  Javier Miranda  <miranda@gnat.com>

	* exp_aggr.adb:
	(Has_Default_Init_Comps): New function to check the presence of
	default initialization in an aggregate.
	(Build_Record_Aggr_Code): Recursively expand the ancestor in case of
	extension aggregate of a limited record. In addition, a new formal
	was added to do not initialize the record controller (if any) during
	this recursive expansion of ancestors.
	(Init_Controller): Add support for limited record components.
	(Expand_Record_Aggregate): In case of default initialized components
	convert the aggregate into a set of assignments.

	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Update the comment
	describing the new syntax.
	Nothing else needed to be done because this subprogram delegates part of
	its work to P_Precord_Or_Array_Component_Association.
	(P_Record_Or_Array_Component_Association): Give support to the new
	syntax for default initialization of components.

	* sem_aggr.adb:
	(Resolve_Aggregate): Relax the strictness of the frontend in case of
	limited aggregates.
	(Resolve_Record_Aggregate): Give support to default initialized
	components.
	(Get_Value): In case of default initialized components, duplicate
	the corresponding default expression (from the record type
	declaration). In case of default initialization in the *others*
	choice, do not check that all components have the same type.
	(Resolve_Extension_Aggregate): Give support to limited extension
	aggregates.

	* sem_ch3.adb:
	(Check_Initialization): Relax the strictness of the front-end in case
	of aggregate and extension aggregates. This test is now done in
	Get_Value in a per-component manner.

	* sem_ch4.adb (Analyze_Allocator): Don't post an error if the
	expression corresponds to a limited aggregate. This test is now done
	in Get_Value.

	* sinfo.ads, sinfo.adb (N_Component_Association): Addition of
	Box_Present flag.

	* sprint.adb (Sprint_Node_Actual): Modified to print an mbox if
	present in an N_Component_Association node

2003-11-13  Thomas Quinot  <quinot@act-europe.fr>

	* sem_ch9.adb (Analyze_Accept_Statement): A procedure hides a
	type-conformant entry only if they are homographs.

2003-11-13  GNAT Script  <nobody@gnat.com>

	* Make-lang.in: Makefile automatically updated
