library files.
Major update of the Project Manager and of the project aware tools,

is a variable that renames a slice, use the variable itself in the

* exp_aggr.ads,

expanded aggregate code before allocator, and ahead of declaration for
temporary, to prevent access before elaboration when the allocator is
an actual for an access parameter.
(Is_Static_Dispatch_Table_Aggregate): Handle aggregates initializing
the TSD and the table of interfaces.
(Convert_To_Assignments): Augment the test for delaying aggregate
expansion for limited return statements to include the case of extended
returns, to prevent creation of an unwanted transient scope.

* sem_ch5.adb: Improve warnings on redundant assignments
* sem_util.ads, sem_util.adb: (Is_Variable): Add defense against junk
parameter
(Is_Synchronized_Tagged_Type): New subprogram that returns true
in case of synchronized tagged types (AARM 3.9.4 (6/2)).
(Safe_To_Capture_Value): Can now return True for constants, even if Cond
is set to False. Improves handling of Known_[Not_]Null.
(Wrong_Type): Special case address arithmetic attempt
(Collect_Abstract_Interfaces): Add new formal to allow collecting
abstract interfaces just using the partial view of private types.
(Has_Abstract_Interfaces): Add new formal to allow checking types
covering interfaces using the partial view of private types.
(Is_Fully_Initialized_Type): Special VM case for uTag component. This
component still needs to be defined in this case, but is never
initialized as VMs are using other dispatching mechanisms.
(Abstract_Interface_List): For a protected type, use base type to get
proper declaration.
Improve warnings on redundant assignments
(Is_Variable): Handle properly an implicit dereference of a prefixed
function call.
(Build_Actual_Subtype): If this is an actual subtype for an
unconstrained formal parameter, use the sloc of the body for the new
declaration, to prevent anomalises in the debugger.

with a derived type declaration, chain the parent type's representation
items to the last representation item of the derived type (not the
first one) if they are not present already.
(Analyze_Object_Declaration, Constant_Redeclaration): Allow incomplete
object declaration of forward references to tags.
(Access_Subprogram_Declaration): In Ada2005, anonymous access to
subprogram types can appear as access discriminants of synchronized
types.
(OK_For_Limited_Init_In_05): The initialization is legal is it is a call
given in prefixed form as a selected component.
(Process_Discriminants): If not all discriminants have defaults, place
error message on a default that is present.

extend a synchronized tagged type.
