        * exp_ch4.adb (Expand_N_Type_Conversion): Perform Integer promotion for
        the operand of the unary minus and ABS operators.

        * sem_type.adb (Covers): A concurrent type and its corresponding record
        type are compatible.
        * exp_attr.adb (Expand_N_Attribute_Reference): Do not rewrite a 'Access
        attribute reference for the current instance of a protected type while
        analyzing an access discriminant constraint in a component definition.
        Such a reference is handled in the corresponding record's init proc,
        while initializing the constrained component.
        * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
        corresponding record type, propagate components'
        Has_Per_Object_Constraint flag.
        * exp_ch3.adb (Build_Init_Procedure.Build_Init_Statements):
        For a concurrent type, set up concurrent aspects before initializing
        components with a per object constrain, because they may be controlled,
        and their initialization may call entries or protected subprograms of
        the enclosing concurrent object.

        * prj-nmsc.adb (Add_If_Not_In_List): New subprogram, for better sharing

        (Find_Source_Dirs): resolve links if Opt.Follow_Links_For_Dirs when
        processing the directories specified explicitly in the project file.
