+	* sem_util.adb (Insert_Explicit_Dereference): When an implicit
+	dereference is rewritten to an explicit one, generate a reference to
+	the entity denoted by its prefix using the original prefix node, so
+	the dereference can be properly recorded as a read of the denoted
+	access value, if appropriate.

+	emitting 'assigned but never read' warning on a variable on the basis
+	that it has an access type.

+	* sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
+	subprogram which is Imported with convention Intrinsic if an
+	External_Name argument is specified.
+	(Process_Import_Or_Interface): Properly diagnose link name argument.
+	(Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
+	with Sem_Ch6.Cannot_Inline.

+	for generation of DSA code targeted to the PolyORB PCS.
+	(Add_Stub_Type): Rewrite to isolate the parts that are specific to one
+	implementation of the partition communication subsystem in ancillary
+	subprograms.
+	(Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
+	PolyORB_Support.Build_Stub_Type): New subrograms containing the
+	PCS-specific part of Add_Stub_Type.
+	(Insert_Partition_Check): Use runtime library function to perform
+	E.4(19) check.
+	* rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
+	(RE_Same_Partition): New entity, from s-parint.

+	ensure proper recording of references.
+2004-12-07  Gary Dismukes  <dismukes@adacore.com>
+	* sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
+	to be resolved later as part of Analyze_Iteration_Scheme's call to
+	Make_Index.
+2004-12-07  Ed Schonberg  <schonberg@adacore.com>
+	* sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

+	Add gnatmetric section
+2004-12-07  Vincent Celier  <celier@adacore.com>
+	* vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and

+	others_decl and all_others_decl instead of hardcoded dummy addresses
+	to represent "others" and "all others" choices, which is cleaner and
+	more flexible with respect to the possible eh pointer encoding policies.
+	* utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
+	(process_attributes): Account for the naming change of the "args"

+	Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
+	(Get_PCS_Name): New subprogram. Returns the name of the PCS currently
+	in use.
+	(Specific_Add_RACW_Features): New subprogram. PCS-specific part of

+	(First_RCI_Subprogram_Id): Document this constant.
+	(Add_RAS_Access_TSS): Correct the setting of the Etype of the

+	is more appropriately moved here. The cleanup involves making sure
+	that the pragmas are properly attached to the tree, and that no
+	nodes are improperly shared.
+	* sem_prag.adb: Move expansion of Common_Object and Psect_Object
+	pragmas to Exp_Prag, which is more appropriate.

+	Use new Make_String_Literal function with string.
+	* exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
+	that are functions return universal values, that have to be converted
+	to the context type.
+	Use new Make_String_Literal function with string.
+	(Get_Stream_Convert_Pragma): New function, replaces the use of

+2004-11-18  Robert Dewar  <dewar@adacore.com>
+	* errout.ads, errout.adb: (First_Sloc): New function

+	    Robert Dewar  <dewar@adacore.com>
+	* exp_ch4.adb (Expand_N_Selected_Component): If the component is the
+	discriminant of a constrained subtype, analyze the copy of the
+	corresponding constraint, because in some cases it may be only
+	partially analyzed.
+	Removes long-lived ??? comments.
+	* exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
+	handled controlled or secondary-stack expressions within the
+	iteration_scheme of a loop.
+	* sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
+	bounds that may contain functions calls, to prevent memory leaks when
+	the bound contains a call to a function that uses the secondary stack.
+	(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
+	generate temporaries for loop bounds that might contain function calls
+	that require secondary stack and/or finalization actions.
+	* sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
+	selected component and the selector is overloadable (not just a
+	function) treat as function call, Analyze_Call will disambiguate if
+	necessary.
+	(Analyze_Selected_Component): Do not generate an actual subtype for the
+	selected component if expansion is disabled. The actual subtype is only
+	needed for constraint checks.
+	(Analyze_Allocator): If restriction No_Streams is set, then do
+	not permit objects to be declared of a stream type, or of a
+	composite type containing a stream.
+	* restrict.ads: Remove the a-stream entry from Unit_Array, since
+	No_Streams no longer prohibits with'ing this package.
+	* sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
+	discriminants, but the parent base has unknown discriminants, there is
+	no discriminant constraint to inherit. Such a discrepancy can arise
+	when the actual for a formal type with unknown discriminants is a
+	similar private type whose full view has discriminants.
+	(Analyze_Object_Declaration): If restriction No_Streams is set, then
+	do not permit objects to be declared of a stream type, or of a
+	composite type containing a stream.
+2004-11-18  Ed Schonberg  <schonberg@adacore.com>
+	* exp_dbug.ads: Update documentation to reflect simpler encoding for

+	of protected operations.
+	(Build_Barrier_Function_Specification): Set the Needs_Debug_Info
+	flag for the protected entry barrier function.
+	(Build_Protected_Entry_Specification): Set the Needs_Debug_Info

+2004-11-18  Ed Schonberg  <schonberg@adacore.com>
+	* exp_pakd.adb (Convert_To_PAT_Type): After replacing the original

+2004-11-18  Ed Falis  <falis@adacore.com>
+	* init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653

+2004-11-18  Jose Ruiz  <ruiz@adacore.com>
+	* s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error

+2004-11-18  Vincent Celier  <celier@adacore.com>
+	* makegpr.adb (Compile): Put the compiling switches (in package
+	Compiler and on the command line) immediately after "-c", instead of
+	at the end of the command line invocation of the compiler, when
+	compiling a non-Ada file.
+	(Build_Global_Archive): When there is no need to rebuild the archive,
+	set Global_Archive_Exists, so that the archive is passed to the linker
+	if one is needed.
+2004-11-18  Robert Dewar  <dewar@adacore.com>
+	    Sergey Rybin  <rybin@adacore.com>
+	* gnat_ugn.texi:
+	Remove extra paren check from list of checks for redundant constructs
+	Add documentation of new -gnatyx style check (check extra parens)
+	Remove paragraph about gnatelim debug options.
+	* gnat_rm.texi: Document that Ada.Streams now forbids creating stream

+	* g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
+	(C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
+	there is no use of GNAT.Sockets.Constants.
+	Remove remaining pragma Import for C_Write
+	Remove C_Read and C_Write from internal implementation unit
+	GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
+	the read and write functions from the system runtime library is fine
+	on UNIX but won't work under Windows).
+	* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
+	(Check_Selector): Use C_Recv instead of C_Read.
+	Selectors are the GNAT.Sockets abstraction to perform a select()
+	call on a set of descriptors. To allow abortion of an ongoing
+	select operation, some data is written to a dedicated socket that
+	is always monitored.
+	Under Windows, the write and read library functions cannot operate
+	on sockets, so we need to use send and recv instead, which is portable
+	across all supported platforms.
+	* g-socthi.ads: Remove C_Read and C_Write from internal implementation
+	unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
+	(using the read and write functions from the system runtime library is
+	fine on UNIX but won't work under Windows).
+2004-10-26  Nicolas Setton  <setton@act-europe.fr>

+	the low level EH init subprogram to be called from __gnat_initialize.
+	* mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
+	indicates which options to pass to the archive indexer.
+	* mlib-utl.adb: Add support for calling ranlib with additional
+	options. This is needed for instance under Mac OS X.
+	(Ranlib_Options): New global variable, used to store the potential
+	options to pass to ranlib.
+	(Ar): Use Ranlib_Options when spawning ranlib.
+	(Initialize): Set the value of ranlib option.
+2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
+	* s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K

+	in the ZCX case.
+2004-10-26  Pascal Obry  <obry@gnat.com>
+	* s-parame-mingw.adb (Default_Stack_Size): Add some comments.
+	* s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
+	Windows only the initial thread stack size can be set so it is good to
+	start we a low stack size.
+	The OS will adjust the size as needed.
+2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
+	    Nicolas Setton  <setton@act-europe.fr>
+	* expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
+	"__unix__" instead of "unix".
+	The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
+	sections were just mistakenly ignored. The former is
+	implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
+	Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
+	of hpux. This prevents an unwanted definition of the symbol
+	convert_addresses in adaint.o.
+2004-10-26  Gary Dismukes  <dismukes@gnat.com>
+	* a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for

+	expression is the right-hand side of an assignment.
+2004-10-26  Vincent Celier  <celier@gnat.com>
+	* clean.adb (Delete): Do not output warnings when in quiet output and
+	not in verbose mode.
+	(Force_Deletions): New Boolean flag, defaulted to False
+	(Delete): Only delete a file if it is writable, and when
+	Force_Deletions is True.
+	(Parse_Cmd_Line): New switch -f: set Force_Deletions to True
+	(Usage): Line for new switch -f
+	(Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
+	own.
+2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>
+	* decl.c (gnat_to_gnu_field): Use the type of the inner object for a
+	JM type only if its size matches that of the wrapper.  When a size is
+	prescribed and the field is not aliased, remove the wrapper of a JM
+	type only if the size is not greater than that of the packed array.
+	(gnat_to_gnu_entity): Change the extension of packed array wrappers

+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	* exp_aggr.adb (Safe_Component): An aggregate component that is an
+	unchecked conversion is safe for in-place use if the expression of the
+	conversion is safe.
+	(Expand_Array_Aggregate): An aggregate that initializes an allocator may
+	be expandable in place even if the aggregate does not come from source.
+	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the
+	designated object of an allocator in place, rather than building it
+	first on the stack. The previous scheme forces a full copy of the array,
+	and may be altogether unsusable if the size of the array is too large
+	for stack allocation.
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+	* exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array

+	array assignment if the component type is atomic.
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	    Eric Botcazou  <ebotcazou@act-europe.fr>
+	* exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
+	is aliased and is a by_reference type, do not pass by copy.
+	(Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
+	detect whether the call is in the right side of an assignment or
+	the expression of an object declaration.  Recurse on component
+	association within aggregates.
+	Call it in the condition that determines whether the temporary is
+	necessary for correct stack-checking.
+2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
+	* exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
+	RACW_Type, used in the PolyORB version.
+	Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
+	version and the GARLIC version.
+	* snames.ads, snames.adb, s-parint.ads, s-parint.adb:
+	Rename RCI_Info to RCI_Locator for better consistency between the
+	GARLIC and PolyORB versions of the distributed systems annex.
+	(DSA_Implementation_Name): This enumeration lists the possible
+	implementations of the Partition Communication Subsystem for the
+	Distributed Systems Annex (DSA). The three available implementations
+	are the dummy stub implementation (No_DSA), and two versions based on
+	two different distribution runtime libraries: GARLIC and PolyORB. Both
+	the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
+	technology.
+	Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
+	that organization.
+	* rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
+	between the GARLIC and PolyORB versions of the distributed systems
+	annex.
+	Remove RE_Unbounded_Reclaim_Pool since it is unused.
+2004-10-26  Gary Dismukes  <dismukes@gnat.com>

+	* g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,

+	These new routines allow the user to set or unset the Owner execute
+	and Owner write permission flags on a file.
+	* makegpr.adb, mlib.adb, mlib-prj.adb: Use
+	GNAT.OS_Lib.Set_Executable instead of rolling our own.
+2004-10-26  Matthew Gingell  <gingell@gnat.com>
+	* i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
+2004-10-26  Pascal Obry  <obry@gnat.com>
+	* init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
+	memory before the faulting page we properly test the process read
+	access for this address using appropriate Win32 routine.
+	(HPUX sections): guard with "__hpux__" instead of "hpux".
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+	* lib-xref.adb (Generate_Reference): Don't complain about reference to

+2004-10-26  Vincent Celier  <celier@gnat.com>
+	* prj-env.adb: (Contains_ALI_Files): New Boolean function
+	(Ada_Objects_Path.Add): For a library project, add to the object path

+	path defaults to ".:<prefix>/lib/gnat".
+	(Parse): For an extending all project, allow direct import of a project
+	that is virtually extended.
+	* prj-proc.adb (Imported_Or_Extended_Project_From): If a project with

+	an extension of this project is imported, return the ID of the
+	extension.
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+	* s-arit64.adb: (Le3): New function, used by Scaled_Divide
+	(Sub3): New procedure, used by Scaled_Divide

+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	    Javier Miranda  <miranda@gnat.com>
+	* sem_ch12.adb (In_Main_Context): Predicate to determine whether the
+	current instance appears within a unit that is directly in the context
+	of the main unit.
+	Used to determine whether the body of the instance should be analyzed
+	immediately after its spec, to make its subprogram bodies available
+	for front-end inlining.
+	(Analyze_Formal_Array_Type): Cleanup condition that checks that range
+	constraint is not allowed on the component type (AARM 12.5.3(3))
+2004-10-26  Cyrille Comar  <comar@act-europe.fr>
+	* sem_ch13.adb (Analyze_Attribute_Definition_Clause, case

+	documented.
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
+	or protected type with discriminants, do not constrain the
+	corresponding record type if the subtype declaration has no
+	discriminant constraints. This can be the case in source code, or in
+	the subtype declaration created to rename an actual type within an

+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	* sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a

+	(Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
+	includes call to some function that returns an unconstrained type, do
+	not inline.
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+	* sem_elab.adb (Check_Elab_Call): Do not check a call that does not
+	appear in the code for the main unit. Dependencies among units in the
+	context of the main unit are established when those other units are
+	compiled. Otherwise spurious elaboration constraints can generate
+	incorrect elaboration circularities.
+2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
+	    Ed Schonberg   <schonberg@gnat.com>
+	* sem_util.adb (Is_Aliased_View): Defend against the case where this
+	subprogram is called with a parameter that is not an object name. This
+	situation arises for some cases of illegal code, which is diagnosed
+	later, and in this case it is wrong to call Is_Aliased, as that might
+	cause a compiler crash.
+	(Explain_Limited_Type): Refine previous fix to include
+	inherited components of derived types, to provide complete information.
+	* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
+	is the prival for a protected object.
+	It is necessary to mark this entity as a variable, in addition to
+	flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
+	modified to avoid checking the Aliased flag on entities that are not
+	objects. (Checking that flag for non-objects is erroneous and could
+	lead to a compiler crash).
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+	* s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
+	X_Frac = 0.5, then we know that the number X must be positive.
+	(Succ): Remove the same redundant test, and also fix the primary test
+	to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
+	Minor reformatting
+	(Decompose): Add fuller comments to spec
+2004-10-26  Pascal Obry  <obry@gnat.com>
+	* tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
+	validity (process must have read access). Set to 0 in all other cases.
+	(STOP_FRAME): Now check for ptr validity to avoid a segmentation
+	violation on Win32.
+	(VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
+	segmentation violation.
+2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>
+	* trans.c (call_to_gnu): For an (in-)out parameter passed by reference

+	    Vasiliy Fofanov  <fofanov@act-europe.fr>
+	    Vincent Celier   <celier@gnat.com>
+	* gnat_ugn.texi: Generalize "finding memory problems" section into a
+	"memory management issues" section and document some of the useful
+	memory pools provided as part of the GNAT library.
+	Remove "virtual" from declaration of A::method2 in
+	the simple example of Ada/C++ mixed system.
+	Library Projects may be virtually extended: their virtual extensions
+	are not Library Projects.
+	Added section on extending project hierarchies.
+2004-10-19  Aaron W. LaFramboise  <aaronavay62@aaronwl.com>
+	* adaint.c (__gnat_get_libraries_from_registry): Cast value

+2004-10-04  Olivier Hainque  <hainque@act-europe.fr>
+	* s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense

+2004-10-04  Olivier Hainque  <hainque@act-europe.fr>
+	* init.c (__gnat_initialize): Call an Ada subprogram to perform the
+	table registration calls when need be. Ensures no reference to the crt
+	ctors symbol are issued in the SJLJ case, which avoids possible
+	undefined symbol errors in the case of modules to be statically linked
+	with the kernel.
+2004-10-04  Javier Miranda  <miranda@gnat.com>
+	* sem_ch4.adb (Try_Object_Operation): Reformat the code to expand

+	(Get_Simple_Init_Val): Modular packed arrays no longer need to be
+	initialized to zero.
+	* checks.adb (Expr_Known_Valid): Packed arrays are now always
+	considered valid, even if the representation is modular. That's correct
+	now that we no longer initialize packed modular arrays to zero.
+	* exp_dbug.ads: Clarify documentation on handling of PAD and JM
+	suffixes. These are now documented as the only cases in which the
+	debugger ignores outer records.
+	Previously, the spec allowed arbitrary suffixes for this purpose.
+	Change name of LJM to JM for packed array pad records
+	Create separate section on packed array handling, and add a whole new

+	actual that is also the component type of a subsequent array actual.
+	The visibility status of the first actual is not affected when the
+	second is installed.
+	(Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
+	make fully recursive the treatment of formals of packages declared
+	with a box.
+	(Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
+	the above on exit from an instantiation.
+	(Denotes_Formal_Package): When called from Restore_Private_Views, ignore
+	current instantiation which is now complete.
+	(Analyze_Package_Instantiation): No instantiated body is needed if the
+	main unit is generic. Efficient, and avoid anomalies when a instance
+	appears in a package accessed through rtsfind.
+2004-10-04  Ed Schonberg  <schonberg@gnat.com>

+	* exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
+	expansion of Input, to account for the fact that the implicit call
+	generated by the attribute reference must freeze the user-defined
+	stream subprogram. This is only relevant to 'Input, because it can
+	appear in an object declaration, prior to the body of the subprogram.
+	* sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
+	expansion can proceed and further errors uncovered.

+	It is initially set to False in all targets.
+	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack

+	Add_RACW_Read_Attribute.
+	Minor reformatting for better alignment with PolyORB version.
+	Store the entity for the asynchronous flag of an RACW, rather than the
+	expression, in the asynchronous flags table. This will allow this flag

+	Minor reformatting.
+	* freeze.adb (Check_Address_Clause): Remove previous change, not the

+2004-09-21  Olivier Hainque  <hainque@act-europe.fr>
+	* decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a

+	their TYPE_SIZE set already.
+2004-09-21  Robert Dewar  <dewar@gnat.com>
+	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
+	packed array types in both little- and big-endian cases. This change
+	ensures that we no longer count on the unused bits being initialized
+	for such types (and in particular ensures that equality testing will
+	only read the relevant bits).
+	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
+	These changes mean that we no longer need to initialize small packed
+	arrays.
+	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
+	optimization to an LJM field as to its parent field.
+	* ada-tree.h, trans.c, utils.c, utils2.c:

+2004-09-20  Robert Dewar  <dewar@gnat.com>
+	PR ada/17540
+	* freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

+	* prj-attr.ads: Comment updates to indicate that all subprograms may be
+	used by tools, not only by the project manager, and to indicate that
+	exception Prj.Prj_Error may be raised in case of problem.
+	(Add_Unknown_Package, Add_Attribute): Moved to new child package
+	Prj.Attr.PM.
+	(Attrs, Package_Attributes): Table instantiations moved from the body to

+	Detect_Blocking is active and delay is called from a protected
+	operation.
+	* bindgen.adb (Gen_Adainit_Ada): When generating the call to

+2004-03-25  Thomas Quinot  <quinot@act-europe.fr>
+	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
+	attribute reference does not denote a subtype, it can be any
+	expression that has a classwide type, potentially after an implicit
+	dereference.  In particular, the prefix can be a view conversion for
+	a classwide type (for which Is_Object_Reference holds), but it can
+	also be a value conversion for an access-to-classwide type. In the
+	latter case, there is an implicit dereference, and the original node

+2004-03-15  Olivier Hainque  <hainque@act-europe.fr>
+	* s-stalib.ads (Exception_Code): New type, to represent Import/Export

+	* cstand.adb (Create_Standard): Adjust the type of the Import_Code

+	(Scan_Make_Arg): Add the executable suffix only if the argument

+	suffix.  When in verbose mode and executable file name does not end
+	with executable suffix, output the executable name, in canonical case.
+	* s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing

+	(Expand_N_Slice): Same. Always do the rewriting, even for the case
+	of non-packed slices, since the dereference action generated by

+	(Expand_N_Selected_Component): When rewriting an implicit dereference,
+	analyze and resolve the rewritten explicit dereference so it is seen
+	by the expander.
+	(Insert_Dereference_Action): This procedure is now called only for the

+	Minor reformatting and code clean ups.
+	Minor changes to prevent -gnatwa warnings
+	* ali.adb: Minor reformatting and cleanup of code
+	Acquire new SS indication of secondary stack use from ali files
+	* a-numaux.ads: Add Pure_Function pragmas for all imported functions
+	(since now we expect this to be done for imported functions)
+	* bindgen.adb: Generate call to modify default secondary stack size if
+	-Dnnn switch given
+	* bindusg.adb: Add line for new -D switch
+	* exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
+	replacement name for Type_May_Have_Non_Bit_Aligned_Components!
+	Add circuitry for both records and arrays to avoid gigi
+	processing if the type involved has non-bit-aligned components
+	* exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
+	N_String_Literal node always references an E_String_Literal_Subtype
+	entity. This may not be true in the future.
+	(Possible_Bit_Aligned_Component): Move processing of
+	Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
+	* exp_ch6.adb (Expand_Thread_Body): Pick up
+	Default_Secondary_Stack_Size as variable so that we get value modified
+	by possible -Dnnn binder parameter.
+	* exp_util.adb (Component_May_Be_Bit_Aligned): New function.
+	(Type_May_Have_Bit_Aligned_Components): New function.
+	* exp_util.ads (Component_May_Be_Bit_Aligned): New function.
+	(Type_May_Have_Bit_Aligned_Components): New function.
+	* fe.h: (Set_Identifier_Casing): Fix prototype.
+	Add declaration for Sem_Elim.Eliminate_Error_Msg.
+	Minor reformatting.
+	* freeze.adb (Freeze_Entity): Add RM reference to error message about
+	importing constant atomic/volatile objects.
+	(Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
+	unless explicit Pure_Function pragma given, to avoid insidious bug of
+	call to non-pure imported function getting eliminated.
+	* gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
+	gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
+	gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting
+	Add 2004 to printed copyright notice
+	* lib-writ.ads, lib-writ.adb: Put new SS flag in ali file if secondary
+	stack used.
+	* Makefile.rtl: Add entry for g-sestin.o
+	g-sestin.ads: New file.
+	* mdll.adb: Minor changes to avoid -gnatwa warnings
+	* mlib-tgt.adb: Minor reformatting
+	* opt.ads: New parameter Default_Secondary_Stack_Size (GNATBIND)
+	New switch Sec_Stack_Used (GNAT, GNATBIND)
+	Make Default_Secondary_Stack_Size a variable instead of a constant,
+	so that it can be modified by the new -Dnnn bind switch.
+	* rtsfind.adb (Load_Fail): Give full error message in configurable
+	run-time mode if all_errors mode is set. This was not done in the case
+	of a file not found, which was an oversight.
+	Note if secondary stack unit is used by compiler.
+	* sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
+	ineffective elaborate all pragmas on non-visible packages (this
+	happened when a renamed subprogram was called). Now the elaborate all
+	always goes on the package containing the renaming rather than the one
+	containing the renamed subprogram.
+	* sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
+	(Process_Eliminate_Pragma): Add parameter to capture pragma location.
+	* sem_eval.adb (Eval_String_Literal): Do not assume that string literal
+	has an Etype that references an E_String_Literal.
+	(Eval_String_Literal): Avoid assumption that N_String_Literal node
+	always references an E_String_Literal_Subtype entity. This may not
+	be true in the future.
+	* sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
+	pragma location.
+	* sem_res.adb (Resolve): Specialize msg for function name used in proc
+	call.
+2004-01-05  Ed Falis  <falis@gnat.com>
+	* g-debuti.adb: Replaced direct boolean operator with short-circuit
+	form.
+2004-01-05  Vincent Celier  <celier@gnat.com>
+	* bld.adb: Minor comment updates
+	(Process_Declarative_Items): Correct incorrect name (Index_Name instead
+	of Item_Name).
+	* make.adb (Gnatmake): Special process for files to compile/check when
+	-B is specified. Fail when there are only foreign mains in attribute
+	Main of the project file and -B is not specified. Do not skip bind/link
+	steps when -B is specified.
+	* makeusg.adb: Document new switch -B
+	* opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
+	* switch-m.adb: (Scan_Make_Switches): Process -B switch
+	* vms_data.ads: Add new GNAT PRETTY qualifier
+	/FORM_FEED_AFTER_PRAGMA_PAGE for switch -ff
+2004-01-05  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>
+	* trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
+	case.
+	* misc.c (gnat_printable_name): If VERBOSITY is 2, call
+	Set_Identifier_Casing.
+	* decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
+	has size that overflows.
+2004-01-05  Gary Dismukes  <dismukes@gnat.com>
+	* exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
+	-gnatwa warning on static condition.
+2004-01-05  Doug Rupp  <rupp@gnat.com>
+	* link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
+2004-01-05  Arnaud Charlet  <charlet@act-europe.fr>
+	* Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
+	all attributes, including read-only attribute.
+2004-01-05  Pascal Obry  <obry@gnat.com>
+	* bindgen.adb (Gen_Object_Files_Options): Generate the new shared
+	library naming scheme.
+	* mlib-prj.adb (Build_Library): Generate different names for the static
+	or dynamic version of the GNAT runtime. This is needed to support the
+	new shared library naming scheme.
+	(Process_Binder_File): Add detection of shared library in binder file
+	based on the new naming scheme.
+	* gnatlink.adb (Process_Binder_File): Properly detect the new naming
+	scheme for the shared runtime libraries.
+	* Makefile.in:
+	(LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
+	scheme.
+	(install-gnatlib): Do not create symlinks for shared libraries.
+	(gnatlib-shared-default): Idem.
+	(gnatlib-shared-dual-win32): New target. Not used for now as the
+	auto-import feature does not support arrays/records.
+	(gnatlib-shared-win32): Do not create copy for the shared libraries.
+	(gnatlib-shared-vms): Fix shared runtime libraries names.
+	* osint.ads, osint.adb (Shared_Lib): New routine, returns the target
+	dependent runtime shared library name.
+2004-01-05  Vasiliy Fofanov  <fofanov@act-europe.fr>
+	* osint.adb (Read_Library_Info): Remove bogus check if ALI is older
+	than the object.
+2004-01-05  Ed Schonberg  <schonberg@gnat.com>
+	* sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
+	protected objects when allocator has a subtype indication, not a
+	qualified expression. Note that qualified expressions may have to be
+	checked when limited aggregates are implemented.
+	* sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
+	pure, emit warning.
+	(Analyze_Pragma, case Pure_Function): If enclosing package is pure and
+	subprogram is imported, remove warning.
+2004-01-05  Geert Bosch  <bosch@gnat.com>
+	* s-poosiz.adb: Update copyright notice.
+	(Allocate): Use Task_Lock to protect against concurrent access.
+	(Deallocate): Likewise.
+2004-01-05  Joel Brobecker  <brobecker@gnat.com>
+	* s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???
+	comment.
