"a-extiti" -- Ada.Execution_Time.Timers
* 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.

total size of the arguments is too large.

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

parameter Process_Blocking_IO.

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
Library_Symbol_File) it is not the same as the reference symbol file.

has been specified
Correct error message when invocation of the linker fails
Add explicit size clause for the C imported variables
Object_List_File_Supported and Using_GNU_Linker to emphasize that
we expect char size.
Read target parameters earlier, since this is needed to set
Target_VM properly. Also do not use -static/shared-libgcc for non GCC
targets.
From-SVN: r125417

switch -P

* g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
absolute value of Header.Block_Size when displaying the freed physical
memory in traces.
(Allocate): Compute Storage_Address using Integer_Address, not
Storage_Offset, because the range of Storage_Offset may not be large
enough.
(Configure): New parameter Low_Level_Traces
(Allocate, Deallocation, Free_Physically): Added low-level traces
(Configure): new parameter Errors_To_Stdout.
(Output_File): new subprogram
(Deallocate, Dereference): Send error messages to the proper stream
(Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
documented. Previous code would send it to the current output file
defined in GNAT.IO, which might not be stdout
(Is_Valid): Adjust comment to mention that a positive reply means that
Header_Of may be used to retrieve the allocation header associated with
the subprogram Storage address argument. Return False early if this
address argument is misaligned.

Add new warning for renaming of function return objects
* opt.adb (Tree_Write, Tree_Read): Use proper expressions for size

frontend as finished its work and has called the backend to process

unit is a compilation unit, rather than relying on its scope, so that
Standard can be renamed.
(Analyze_Object_Renaming): Add new warning for renaming of function
return objects.
Also reject attempt to rename function return object in Ada 83 mode.
(Attribute_Renaming): In case of tagged types, add the body of the
generated function to the freezing actions of the type.
(Find_Type): A protected type is visible right after the reserved word
"is" is encountered in its type declaration. Set the entity and type
rather than emitting an error message.
(New_Scope): Properly propagate Discard_Names to inner scopes
(Check_Nested_Access): New procedure.
(Has_Nested_Access, Set_Has_Nested_Access): New procedures.
(Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.

* exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
object of a limited type can be initialized with a call to a function
that returns in place. If the limited type has unknown discriminants,
and the underlying type is a constrained composite type, build an actual
subtype from the function call, as is done for private types.
(Side_Effect_Free): An expression that is the renaming of an object or
whose prefix is the renaming of a object, is not side-effect free
because it may be assigned through the renaming and its value must be
captured in a temporary.

as is done for other limited types.
