(Change_To_Object_Directory): In verbose mode, display the name of the
object directory we're changing to.
(Compile_Sources): Make sure, when a project file is used, to compile
the body of the unit, when there is one, even when only the spec is
recorded in an ALI file.
(Gcc_Switches, Binder_Switches, Linker_Switches): Tables moved from the
spec to the body.
(Report_Compilation_Failed): New procedure
(Bind, Display_Commands, Compile_Sources, Initialize, Scan_Make_Arg):

* sem_ch12.adb (Analyze_Associations): Diagnose use of an others
association in an instance.
(Copy_Generic_Node): If the node is a string literal, no need to copy
its descendants.
(Is_Generic_Formal): For a formal subprogram, the declaration is the
grandparent of the entity.
(Analyze_Formal_Interface_Type): Transform into a full type declaration,
to simplify handling of formal interfaces that derive from other formal
interfaces.
(Instantiate_Subprogram_Body): The defining unit name of the body of
the instance should be a defining identifier.
(Install_Formal_Packages): make global to the package, for use in
instantiations of child units.
(Analyze_Package_Instantiation): Do not attempt to set information on an
enclosing master of an entry when expansion is disabled.
(Instantiate_Type): If the actual is a tagged synchronized type and the
generic ancestor is an interface, create a generic actual for the
corresponding record.
(Analyze_Formal_Derived_Interface_Type): Rewrite as a derived type
declaration, to ensure that the interface list is processed correctly.
(Inline_Instance_Body): If enclosing scope is an instance body, remove
its entities from visibiility as well.
(Pre_Analyze_Actuals): if the actual is an allocator with constraints
given with a named association, analyze the expression only, not the
discriminant association itself.
(Reset_Entity): If the analysis of a selected component is transformed
into an expanded name in the prefix of a call with parameters, do not
transform the original node into an expanded name, to prevent visibility
errors in the case of nested generics.
(Check_Private_View): For an array type, check whether the index types
may need exchanging.

* init.c: Do not adjust IP of an imported VMS exception of ia64.
LIB$STOP is called to raise an exception and the IP of the exception
is the instruction right after the call.

(__gnat_error_handler, AIX): Accept SIGINFO related arguments and call
adjust_context_for_raise before Raise_From_Signal_Hanler.
(__gnat_install_handler, AIX): Add SA_SIGINFO to the sa_flags, to ensure
siginfo is passed to the handler, necessary to let the zcx propagation
engine unwind past it.

* mlib-prj.ads, mlib-prj.adb
(Build_Library): Use untouched object dir and library dir. At the
same time makes sure that the checks are done using the canonical
form. Removes hard-coded directory separator and use the proper host
one instead.
(Process_Project): Do not look in object directory to check if libgnarl
is needed for a library, if there is no object directory.
(Build_Library): Scan the ALI files to decide if libgnarl is needed for
linking.

instead of the hardcoded forward slash which is not the proper
character on Windows for example.

(Raise_Host_Error): Use Host_Error_Message from platform-specific thin
binding to obtain proper message.
(Close_Selector): Use GNAT.Sockets.Thin.Signalling_Fds.Close.
Replace various occurrences of Arry (Arry'First)'Address with the
equivalent Arry'Address (GNAT always follows implementation advice from
13.3(14)).
(Get_Host_By_Address, Get_Host_By_Name,
Get_Service_By_Name, Get_Service_By_Port): Do not use GNAT.Task_Lock;
instead, rely on platform-specific task safe netdb operations provided

proper casing on non case-sensitive platforms like Windows.

on all platforms, as it is not possible to know which one is allowed
before processing the project files.
(Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
specified when symbol policy is Direct. Check that when there is a
symbol file defined (either by default or with attribute
