[multiple changes] 

2003-12-08  Jerome Guitton  <guitton@act-europe.fr>

	* 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
	i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
	obsolete files.

	* Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
	(rts-zfp): Ditto.

2003-12-08  Robert Dewar  <dewar@gnat.com>

	* 7sintman.adb: Minor reformatting

	* bindgen.adb: Configurable_Run_Time mode no longer suppresses the
	standard linker options to get standard libraries linked. We now plan
	to provide dummy versions of these libraries to match the appropriate
	configurable run-time (e.g. if a library is not needed at all, provide
	a dummy empty library).

	* targparm.ads: Configurable_Run_Time mode no longer affects linker
	options (-L parameters and standard libraries). What we plan to do is
	to provide dummy libraries where the libraries are not required.

	* gnatbind.adb: Minor comment improvement

2003-12-08  Javier Miranda  <miranda@gnat.com>

	* exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
	aggregate in the parent. Otherwise constants with limited aggregates
	are not supported. Add new formal to pass the component type (Ctype).
	It is required to call the corresponding IP subprogram in case of
	default initialized components.
	(Gen_Assign): In case of default-initialized component, generate a
	call to the IP subprogram associated with the component.
	(Build_Record_Aggr_Code): Remove the aggregate from the parent in case
	of aggregate with default initialized components.
	(Has_Default_Init_Comps): Improve implementation to recursively check
	all the present expressions.

	* exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
	to indicate that the initialization call corresponds to a
	default-initialized component of an aggregate.
	In case of default initialized aggregate with tasks this parameter is
	used to generate a null string (this is just a workaround that must be
	improved later). In case of discriminants, this parameter is used to
	generate a selected component node that gives access to the discriminant
	value.

	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
	subprogram, based on Build_Task_Allocate_Block, but adapted to expand
	allocated aggregates with default-initialized components.

	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
	the box notation is used in positional aggregates.

2003-12-08  Samuel Tardieu  <tardieu@act-europe.fr>

	* lib.ads: Fix typo in comment

2003-12-08  Vincent Celier  <celier@gnat.com>

	Set the scanner to return ends of line and comments as tokens, if

	(Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
	comments are associated with these nodes. Store the node IDs in the
	With_Records.
	(Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
	With_Records.
	(Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
	the N_Project node. Call Tree.Save and Tree.Reset before scanning the
	current project. Call Tree.Restore afterwards. Set the various nodes
	for comment storage (Next_End, End_Of_Line, Previous_Line,
	Previous_End).

	* prj-part.ads (Parse): New Boolean parameter Store_Comments,
	defaulted to False.

	* prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
	to False. When Truncated is True, truncate the string, never go to the
	next line.
	(Write_End_Of_Line_Comment): New procedure
	(Print): Process comments for nodes N_With_Clause,
	N_Package_Declaration, N_String_Type_Declaration,
	N_Attribute_Declaration, N_Typed_Variable_Declaration,
	N_Variable_Declaration, N_Case_Construction, N_Case_Item.
	Process nodes N_Comment.

	* prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
	without comments and there are some comments, set the flag
	Unkept_Comments to True.
	(Scan): If there are comments, set the flag Unkept_Comments to True and
	clear the comments.
	(Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
	(Next_End_Nodes: New table
	(Comment_Zones_Of): New function

	(There_Are_Unkept_Comments): New function
	(Set_Previous_Line_Node, Set_Previous_End_Node): New procedures

	procedures.
	(First_Comment_After, First_Comment_After_End): New functions
	(First_Comment_Before, First_Comment_Before_End): New functions
	(Next_Comment): New function
	(End_Of_Line_Comment, Follows_Empty_Line,
	Is_Followed_By_Empty_Line): New functions

	(Comment_Id): New global variable

	* scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
	defaulted to False.
	(Scan): Store position of start of comment. If comments are tokens, set
	Comment_Id and set Token to Tok_Comment when scanning a comment.
	(Set_Comment_As_Token): New procedure

	* sinput-p.adb: Update Copyright notice
	(Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
	that no longer exists.

2003-12-08  Javier Miranda  <miranda@gnat.com>

	* sem_aggr.adb: Add dependence on Exp_Tss package
	Correct typo in comment
	(Resolve_Aggregate): In case of array aggregates set the estimated
	type of the aggregate before calling resolve. This is needed to know
	the name of the corresponding IP in case of limited array aggregates.
	(Resolve_Array_Aggregate): Delay the resolution to the expansion phase
	in case of default initialized array components.

	* sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
	types. Required to give support to limited aggregates in generic
	formals.

2003-12-08  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch3.adb (Check_Initialization): For legality purposes, an
	inlined body functions like an instantiation.
	(Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
	until bounds are analyzed, to diagnose premature use of type.

	* sem_util.adb (Wrong_Type): Improve error message when the type of
	the expression is used prematurely.
