Remove obsolete pragma Persistent_Data, Persistent_Object
Set Ada_Version_Explicit, for implementation of AI-362
Test Ada_Version_Explicit for Preelaborate_05 and Pure_05
Add processing for pragma Pure_05 and Preelaborate_05
Add processing for Assertion_Policy pragma
Add pragma identifiers for Assert
(Analyze_Pragma, case Assert): Check number of arguments
(Process_Inline): Additional guard against an illegal program, where the
argument of the pragma is undefined, and warnings on redundant
constructs are enabled.
(Analyze_Pragma, case Obsolescent): Allow an optional second argument
Ada_05 to this pragma, specifying that the pragma is only active in
Ada_05 mode.
(Check_Arg_Order): New procedure
Add appropriate calls to this procedure throughout
Also throughout, check entity name before doing any other checks
* snames.h snames.ads, snames.adb: Add pragma Persistent_BSS

Add entries for pragma Pure_05 and Preelaborate_05
Add entries for Assertion_Policy pragma and associated names
Add some names for pragma argument processing
* tbuild.ads, tbuild.adb: (Make_Linker_Section_Pragma): New function

* exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
of using Set_Renaming_TSS. This ensures that the TSS bodies are not
analyzed if expansion is disabled (which could otherwise cause spurious
error messages if expansion has been disabled due to previous
(unrelated) errors).
* sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
is disabled, the entity denoted by the argument is the access type
itself, not an underlying record type, so there is no need to go back
to the Corresponding_Remote_Type.

* atree.ads, atree.adb: Add support for Elist24 field
* atree.h: Fix wrong definition of Field27
Add support for Elist16 field
Add support for Elist24 field
* einfo.ads, einfo.adb (Abstract_Interfaces,
Set_Abstract_Interfaces): New subprograms.
(Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
subprograms.
(Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
entities rather than a single node.
(Is_Interface, Set_Is_Interface): New subprogram
(First_Tag_Component): New syntesized attribute
(Next_Tag_Component): New synthesized attribute
(Write_Entity_Flags): Upgraded to write Is_Interface
(Write_Field24_Name): Upgraded to write Abstract_Interfaces
(Write_Field25_Name): Upgraded to write Abstract_Interface_Alias
(Task_Body_Procedure): New subprogram to read this attribute.
(Set_Task_Body_Procedure): New subprogram to set this attribute.
(Has_Controlled_Component): Now applies to all entities.
This is only a documentation change, since it always worked to apply
this to other than composite types (yielding false), but now this is
official.
Update documentation on Must_Be_Byte_Aligned for new spec
* tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
uses of the Access_Disp_Table attribute to reference the first dispatch
table associated with a tagged type. As
part of the implementation of abstract interface types,
Access_Disp_Table has been redefined to contain a list of dispatch
tables (rather than a single dispatch table).
Similarly, upgrade all the references to Tag_Component by the
new attribute First_Tag_Component.
(Find_Inherited_TSS): Moved to exp_tss.
Clean up test in Expand_N_Object_Declaration for cases
where we need to do a separate assignment of the initial value.
(Expand_N_Object_Declaration): If the expression in the
declaration of a tagged type is an aggregate, no need to generate an
additional tag assignment.
(Freeze_Type): Now a function that returns True if the N_Freeze_Entity
is to be deleted.
Bit packed array ops are only called if operands are known to be
aligned.
(Component_Equality): When returning an N_Raise_Program_Error statement,
ensure that its Etype is set to Empty to avoid confusing GIGI (which
expects that only expressions have a bona fide type).
(Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
determine the amount of data to be copied.
* par.adb (P_Interface_Type_Definition): New subprogram that parses the
new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
INTERFACE_TYPE_DEFINITION ::=
[limited | task | protected | synchronized] interface
[AND interface_list]
* par-ch3.adb (P_Type_Declaration): Modified to give support to
interfaces.
(P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
interfaces.
(P_Interface_Type_Definition): New subprogram that parses the new
syntax rule of Ada 2005 interfaces
(P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
messages by the correct RENAMES (quotes removed).
* sem_prag.adb: Upgrade all the references to Tag_Component by the new
attribute First_Tag_Component.
* sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
(Interface_List, Set_Interface_List): New subprograms.
(Interface_Present, Set_Interface_Present): New subprograms.
(Limited_Present, Set_Limited_Present): Available also in derived
type definition nodes.
(Protected_Present, Set_Protected_Present): Available also in
record type definition and
derived type definition nodes.
(Synchronized_Present, Set_Synchronized_Present): New subprograms.
(Task_Present, Set_Task_Present): New subprogram.
(Task_Body_Procedure): Removed.
(Set_Task_Body_Procedure): Removed.
These subprogram have been removed because the attribute
Task_Body_Procedure has been moved to the corresponding task type
or task subtype entity to leave a field free to store the list
of interfaces implemented by a task (for AI-345)
Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
(Null_Exclusion_Present): Change to Flag11, to avoid conflict with
expression flag Do_Range_Check
(Exception_Junk): Change to Flag7 to accomodate above change
(Box_Present, Default_Name, Specification, Set_Box_Present,
Set_Default_Name, Set_Specification): Expand the expression
"X in N_Formal_Subprogram_Declaration" into the corresponding
two comparisons. Required to use the csinfo tool.
* exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
"with string" given.
* sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
expression given.
* par-ch11.adb (P_Raise_Statement): Recognize with string expression
in 2005 mode
* exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
attribute Task_Body_Procedure rather than the old semantic field that
was available in the task_type_declaration node.
* par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
interface type definitions.
(P_Formal_Derived_Type_Definition): Modified to handle the list of
interfaces.
* par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
task type declaration.
(P_Protected): Modified to handle the list of interfaces in a
protected type declaration.

* i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
describing the new layout.
(Dispatch_Table): The expander computes the actual array size, allocates
the Dispatch_Table record accordingly, and generates code that displaces
the base of the record after the Typeinfo_Ptr component. The access to
these components is done by means of local functions.
(Offset_To_Top): New function.
(Typeinfo_Ptr): New function.
(Get_TSD): Modified to access the new position of the TSD.

dispatching, setting the controlling status of the formal parameters
and result, and issuing an error if there is no controlling type for
the formal subprogram.

which is an unclean use of that field, we set the new field
Corresponding_Formal_Spec to make the formal subprogram available to
processing in Analyze_Subprogram_Declaration.

Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
Constrained, so that it is is does not statically match its anonymous
base type.
* sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
abstract formal subprograms in error check for functions returning
abstract types. Set scope of new designator for
a parameterless subprogram, so that it is available when checking the
body for nested subprograms, before full analysis of said body.
(Analyze_Subprogram_Body): Warn on inlining bodies with nested
subprogram only if inner one comes from source.
(Analyze_Function_Call): If the call is given in object notation, the
analysis of the name rewrites the node and analyzes it with the proper
argument list. After analyzing the name, if the call has been rewritten
and the result type is set, no further analysis is needed.
(Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
mark in function specification, in a context where the formals are
visible and hide outer homographs.
* sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
as the tagged type for the cases of abstract formal subprograms and
renamings of those. Clean up spec comments.

procedure", covering the case of a call to a formal abstract procedure
that has statically tagged operands.
(Check_Dispatching_Call): Check for the case of an actual given by
a tag-indeterminate function call whose type is an ancestor of the
containing call's associated tagged type. This situation can occur

use the tagged type's tag directly as the controlling argument for
the calls.
(Expand_Call): Name change on call to Expand_Dispatch_Call.
* sprint.adb (Sprint_Node_Actual): Split
N_Formal_Subprogram_Declaration into two alternatives for the new
cases N_Formal_Abstract_Subprogram_Declaration and

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.

PR ada/17540
* sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
instead do this at freeze time (we won't do it if there is an address
clause).
Change "pragma inline" to "pragma Inline" in information and error
messages.
Minor reformatting.

Detect_Blocking is active and delay is called from a protected
operation.
* bindgen.adb (Gen_Adainit_Ada): When generating the call to
__gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma

* gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
package.
* s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
(Register_Receiving_Stub): Add Subp_Info formal parameter.
Update API in placeholder implemetation of s-parint to reflect changes
in distribution runtime library.
* sem_ch3.adb (Expand_Derived_Record): Rename to
Expand_Record_Extension.
* sem_disp.adb (Check_Controlling_Formals): Improve error message for
primitive operations of potentially distributed object types that have
non-controlling anonymous access formals.
* sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
subprogram.
New implementation of expansion for remote access-to-subprogram types,
based on the RACW infrastructure.
This version of sem_dist is compatible with PolyORB/DSA as well as
GLADE.
* sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
Asynchrronous that applies to a remote access-to-subprogram type, mark
the underlying RACW type as asynchronous.

GNAT.Perfect_Hash package.
* atree.adb: Minor reformatting
* exp_ch3.adb (Expand_Derived_Record): Rename to
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.
* exp_ch3.ads (Expand_Derived_Record): Rename to
Expand_Record_Extension.
* exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
Returns the RACW type used to implement a remote access-to-subprogram
type.

subprogram. The proxy object is used as the designated object
for RAS values on the same partition (unless All_Calls_Remote applies).
(Build_Get_Unique_RP_Call): New subprogram. Build a call to
System.Partition_Interface.Get_Unique_Remote_Pointer.
(Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
Renamed from Add_RAS_*_Attribute.

subprograms.
New implementation of expansion for remote access-to-subprogram types,
based on the RACW infrastructure.

function can copy the specification from either a subprogram
specification or an access-to-subprogram type definition.
2004-09-09 Ed Schonberg <schonberg@gnat.com>

* lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
includes case of a variable referenced on the left hand side of an
assignment, therefore remove redundant code. Variables and prefixes of
indexed or selected components are now marked as referenced on left
hand side. Warnings are now properly emitted when variables or prefixes
are assigned but not read.
* sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
left hand side referenced variables. Private access types do not
produce the warning "variable ... is assigned but never read".
Add also additional checks to left hand side referenced variables.
Aliased, renamed objects and access types do not produce the warning
"variable ... is assigned but never read" since other entities may read
the memory location.

* a-ngcoty.adb (Modulus): In alternate formula for large real or
imaginary parts, use Double precision throughout.
* a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only

this may also be instantiated in user code that is compiled with -gnata.
2004-03-15 Olivier Hainque <hainque@act-europe.fr>
* s-stalib.ads (Exception_Code): New type, to represent Import/Export
codes. Having a separate type for this is useful to enforce consistency
throughout the various run-time units.
(Exception_Data): Use Exception_Code for Import_Code.
* s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
Natural and Integer in various places.

complex condition to decide if the current choice at hand catches the
propagated occurrence.

System.Standard_Library.Exception_Code, to allow references from the
pragma import/export expander.

New accessors to allow easy access to GNAT exception data
characteristics.
(GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
redundant Handled_By_Others component, helper for the personality
routine which will now be able to call the appropriate exception data
accessor instead.
* cstand.adb (Create_Standard): Adjust the type of the Import_Code
component of Standard_Exception_Type to be the closest possible to
Exception_Code in System.Standard_Library, that we cannot get at this
point. Expand a ??? comment to notify that this type node should
probably be rewritten later on.
* exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
registration call to include a pointer to the exception object in the
arguments.
* init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

taken care of in Scan_Make_Arg.
(Scan_Make_Arg): Add the executable suffix only if the argument
following -o, in canonical case, does not end with the executable
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
to avoid warnings when instantiating Ada.Task_Attributes.
Minor reformating.
* mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
in the correct order.
* prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
redirect standard output and error to a file for the invocation of the
compiler, then read the file.
* prj-nmsc.adb (Find_Sources): Use the Display_Value for each
directory, instead of the Value.
(Find_Source_Dirs): Remove useless code & comments.
2004-03-15 Ed Schonberg <schonberg@gnat.com>
* exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
tagged type is inherited, and the parent operation is not frozen yet,
force generation of a freeze node for the inherited operation, so the
corresponding dispatch entry is properly initialized.
(Make_Predefined_Primitive_Specs): Check that return type is Boolean
when looking for user-defined equality operation.
* exp_ch4.adb (Expand_Composite_Equality): Check that return type is
boolean when locating primitive equality of tagged component.
* exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
bit-aligned field and the right-hand side a string literal, introduce
a temporary before expanding assignment into a loop.
* exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
priority in full, to ensure that any expanded subepxressions of it are
elaborated in the scope of the init_proc.

after object declaration, skipping over code that may have been
generated for validity checks.
* sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
discriminants, ignore the known discriminants of its full view, if
any, to check legality.
* sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
component if type has unknown discriminants.
(Analyze_Private_Extension_Declaration): Discriminant constraint is
null if type has unknown discriminants.
* sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
for end label when present.
* s-fileio.adb (Open): When called with a C_Stream, use given name for
temporary file, rather than an empty string.

FUNCTION_BOUNDARY; always use TYPE_ALIGN.
2004-03-15 Thomas Quinot <quinot@act-europe.fr>
* 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID.
* exp_ch4.adb (Expand_N_Indexed_Component): Do not call
Insert_Dereference_Action when rewriting an implicit dereference into
an explicit one, this will be taken care of during expansion of the
explicit dereference.
(Expand_N_Slice): Same. Always do the rewriting, even for the case
of non-packed slices, since the dereference action generated by
expansion of the explicit dereference is needed in any case.
(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
expansion of an N_Explcit_Dereference_Node. Do insert a check even for
dereferences that do not come from source (including explicit
dereferences resulting from rewriting implicit ones), but do not
recursively insert a check for the dereference nodes contained within
the check.
(Insert_Dereference_Action): Clarify and correct comment.

syntax rule for object renaming declarations.
(P_Array_Type_Definition): Give support for the Ada 0Y syntax rule for
component definitions.
* sem_ch3.adb (Analyze_Component_Declaration): Give support to access
components.
(Array_Type_Declaration): Give support to access components. In addition
it was also modified to reflect the name of the object in anonymous
array types. The old code did not take into account that it is possible
to have an unconstrained anonymous array with an initial value.
(Check_Or_Process_Discriminants): Allow access discriminant in
non-limited types.
(Process_Discriminants): Allow access discriminant in non-limited types
Initialize the new Access_Definition field in N_Object_Renaming_Decl

No_Requeue_Statements instead of the old No_Requeue for defining the
restricted profile.
* sem_ch9.adb (Analyze_Requeue): Check the new restriction
No_Requeue_Statements.
* s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)
that supersedes the GNAT specific restriction No_Requeue. The later is
kept for backward compatibility.
2004-02-02 Ed Schonberg <schonberg@gnat.com>
* lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,
5staprop.adb, atree.adb, atree.ads, g-crc32.ads: Remove redundant

handlers in the environment thread. This allows proper propagation of
an exception on stack overflows in this thread even when the builtin
ABI stack-checking scheme is used without support for a stack reserve
region.
* utils.c (create_field_decl): Augment the head comment about bitfield
creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
here, because the former is not accurate enough at this point.
Let finish_record_type decide instead.
Don't make a bitfield if the field is to be addressable.
Always set a size for the field if the record is packed, to ensure the
checks for bitfield creation are triggered.
(finish_record_type): During last pass over the fields, clear
DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
from DECL_BIT_FIELD.

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

* 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.

always references an E_String_Literal_Subtype entity. This may not
be true in the future.

pragma location.
* sem_res.adb (Resolve): Specialize msg for function name used in proc
call.
2004-01-05 Ed Falis <falis@gnat.com>

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

case.
* misc.c (gnat_printable_name): If VERBOSITY is 2, call
Set_Identifier_Casing.

* 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.

than the object.
2004-01-05 Ed Schonberg <schonberg@gnat.com>

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.
