        * 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  

        * 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.

        comments are associated with these nodes. Store the node IDs in the

        With_Records.

        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.

        Correct typo in comment

        (Resolve_Aggregate): In case of array aggregates set the estimated

        in case of default initialized array components.

        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.

        constant.

        before calling a signal handler, which is necessary to be able to

        unwind past it. Update the copyright notice.
