+
+	* sem_util.adb (Insert_Explicit_Dereference): When an implicit
+	dereference is rewritten to an explicit one, generate a reference to

+	the dereference can be properly recorded as a read of the denoted
+	access value, if appropriate.
+
+	* sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
+	emitting 'assigned but never read' warning on a variable on the basis
+	that it has an access type.

+	an external name, to be handled by the back end.
+
+	* 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.

+	Minor reformatting.
+	(PolyORB_Support.Helpers): New subunit containing supporting subprograms
+	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

+	* nlists.adb (Prepend_Debug): Remove parameters and nest within
+	Prepend.
+	(Remove_Next_Debug): Same fix
+
+	* nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

+
+2004-12-07  Thomas Quinot  <quinot@adacore.com>
+

+
+2004-12-07  Gary Dismukes  <dismukes@adacore.com>

+
+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

+	and -eit to -ept. Added qualifier
+	/ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
+
+2004-11-27  Andreas Schwab  <schwab@suse.de>
+
+	* Make-lang.in (ada/trans.o): Depend on $(EXPR_H).

+
+	* g-socthi-mingw.ads, g-socthi-vms.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

+
+	* gigi.h (others_decl, all_others_decl): New decls representing the

+	corresponding objects exported by a-exexpr, instead of hardcoded dummy
+	addresses.
+
+	* trans.c (Exception_Handler_to_gnu_zcx): Use the address of
+	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"

+	of 0 for trees.

+
+	* a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

+
+2004-11-18  Thomas Quinot  <quinot@adacore.com>
+
+	* exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
+	procedures factors the common processing for building an RPC receiver

+	(Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
+	replaced with calls to Get_Library_Unit_Name_String. Previously there
+	were several instances of the same code in different locations in the
+	compiler; this checkin completes the replacement of all of these
+	instances with calls to a common subprogram.
+	Minor reformatting.
+
+	* sem_dist.adb: Remove comment noting that RPC receiver generation
+	should be disabled for RACWs that implement RASs.
+	(Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
+

+
+	* einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
+	(Has_Rep_Pragma): New function
+	(Has_Attribute_Definition_Clause): New function
+	(Record_Rep_Pragma): Moved here from sem_ch13.adb
+	(Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
+
+	* sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
+
+	* exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
+	(Expand_Pragma_Psect_Object): New procedure
+	These procedures contain the revised and cleaned up processing for
+	these two pragmas. This processing was formerly in Sem_Prag, but
+	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.
+	Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
+	check for duplicates Remove use of Is_Psected flag, no longer needed.
+	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
+	Get_Rep_Pragma, which had to be kludged to work in this case.
+
+	* freeze.adb: Use new Has_Rep_Pragma function
+
+	* exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal

+
+	* errout.ads, errout.adb: (First_Sloc): New function
+
+	* par-ch5.adb (P_Condition): Check for redundant parens is now a style
+	check (-gnatyx) instead of being included as a redundant construct
+	warning.
+
+	* sem_ch6.adb: Change name Style_Check_Subprogram_Order to
+	Style_Check_Order_Subprograms.
+
+	* style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,

+
+	* 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
+	protected operations.
+
+	* exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
+	generated name, it complicates decoding in gdb and hinders debugging
+	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
+	flag for the protected entry function.

+
+	* lang-specs.h: Change the placement of the %1 marker.
+	Works around the fact that gcc adds -fPIC by default under Darwin.
+
+2004-11-18  Ed Schonberg  <schonberg@adacore.com>
+
+	* exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
+	type of the object with the packed array type, set the Analyzed flag
+	on the object if it is an entity or simple indexed component, to avoid
+	spurious type errors.
+
+2004-11-18  Gary Dismukes  <dismukes@adacore.com>
+

+	separate line from the version message.
+
+2004-11-18  Ed Falis  <falis@adacore.com>
+
+	* init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
+	vthreads.
+	(init_float): Eliminate initialization of floating point status for
+	AE653. The instructions have no effect for vThreads.

+2004-11-18  Vincent Celier  <celier@adacore.com>
+
+	* make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when

+
+2004-11-18  Jose Ruiz  <ruiz@adacore.com>
+
+	* s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
+	for Detect_Blocking which is redundant with the check done within the
+	procedure Protected_Single_Entry_Call.
+	(Lock_Read_Only_Entry): Remove the code for raising Program_Error for
+	Detect_Blocking which is redundant with the check done within the
+	procedure Protected_Single_Entry_Call.
+
+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.

+	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
+	objects rather than forbidding dependencies on the package Ada.Streams.
+
+	* sinfo.ads: Add ??? note that we should document pragmas passed to
+	back end.
+
+	* g-expect.ads: Fix a few typos in the comments.

+
+	* 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>
+
+	* mlib-tgt-darwin.adb: New file.

+	subprogram body.
+
+	* Makefile.in: Add support for building shared libraries under Darwin.
+	(EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
+	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
+	instead of 8K, to reflect the real potential needs for stack-checking
+	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

+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* checks.adb (Expr_Known_Valid): If floating-point validity checks are
+	enabled, check the result of unary and binary operations when the
+	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
+	from LJM to JM.
+
+2004-10-26  Geert Bosch  <bosch@gnat.com>
+
+	* eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.

+	(Pred): Implement in terms of Succ.
+
+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
+	compares if the component is atomic.
+
+	* exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
+	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>
+
+	* gnat1drv.adb: Suppress calling the back end when
+	Frontend_Layout_On_Target is true.
+
+2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
+
+	* g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
+	Set_Read_Only): New subprograms.
+	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
+	entry parameter if pragma Unreferenced set, since we do not properly
+	handle the case of multiple parameters.
+
+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
+	the library directory only if there is no object directory or if the
+	library directory contains ALI files.
+	(Set_Ada_Paths.Add.Recursive_Add): Ditto
+
+2004-10-26  Vincent Celier  <celier@gnat.com>
+
+	* prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
+	extension of library projects.
+
+	* prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
+	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
+	the specified name is directly imported, return its ID. Otherwise, if
+	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
+	(Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
+	correct more than one instance of failure to propagate carries

+	(Double_Divide): Handle overflow case of largest negative number
+	divided by minus one.
+
+	* s-arit64.ads (Double_Divide): Document that overflow can occur in

+	accessibility check to prefix that is a protected operation.
+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch10.adb (Optional_Subunit): If file of expected subunit is
+	empty, post message on stub.
+
+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

+	internal pools.
+
+	* impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
+
+	* s-pooglo.ads: Add more documentation now that this pool is properly
+	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
+	instantiation.
+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
+	different kind of stub (possibly wrong name for file), do not check
+	for conformance.
+	(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

+	now that we no longer initialize packed modular arrays to zero.
+
+	* exp_dbug.ads: Clarify documentation on handling of PAD and JM

+	debugger ignores outer records.
+	Previously, the spec allowed arbitrary suffixes for this purpose.

+	Expand_Record_Extension.
+	(Build_Record_Init_Proc.Build_Assignment): The default expression in
+	a component declaration must remain attached at that point in the
+	tree so New_Copy_Tree copies it if the enclosing record type is derived.
+	It is therefore necessary to take a copy of the expression when building
+	the corresponding assignment statement in the init proc.
+	As a side effect, in the case of a derived record type, we now see the
+	original expression, without any rewriting that could have occurred
+	during expansion of the ancestor type's init proc, and we do not need
+	to go back to Original_Node.
+

+	produce the warning "variable ... is assigned but never read".
+	Add also additional checks to left hand side referenced variables.

+
+	* a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi

+	 - do not rely on Original_Node being present (Analyze_Assignment
+	   calls Note_Possible_Modification on a copied tree).

+	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.

+
+	* 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

+	* 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.

+	-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

+	* 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.
