+ we also remove redundant code found by the new warnings.

+
+2007-10-15 Emmanuel Briot <briot@adacore.com>
+
+ * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
+ value.
+ (Xref_Record): Change type for Line, since in the case of a reference to
+ a predefined entity (as happens for array index types), the line is set
+ to 0.
+ Add support for parsing multiple array index types info, or
+ multiple inherited interfaces info. This information cannot be stored
+ in Xref_Entity_Record, which only supports a single instance of Tref_*,
+ and is therefore stored in the list of references instead. It has a
+ special treatement later on in tools that use this information.
+
+2007-10-15 Tristan Gingold <gingold@adacore.com>
+
+ * debug.adb: Document use of -gnatd.a and -gnatd.I
+
+ * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.
+
+2007-10-15 Javier Miranda <miranda@adacore.com>
+
+ * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
+ Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
+ care of access to class-wide interface types plus removal of bizarre
+ conversion of tagged object to access type (reported by Gary
+ Dismukes). After this patch there is no need to perform any
+ additional management on these nodes in Expand_Interface_Actuals.
+
+ * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
+ that handles use of 'Access and 'Unchecked_Access applied to
+ actuals covering interface types. Such code is now
+ centralized in Expand_N_Attribute_Reference.
+
+2007-10-15 Ed Schonberg <schonberg@adacore.com>
+
+ * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
+ of tagged types whose ultimate ancestor is a CPP type.
+ (Freeze_Array_Type): For a packed array type, generate an initialization
+ procedure if the type is public, to handle properly a client that
+ specifies Normalize_Scalars.
+

+
+ * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

+
+ * mlib-tgt-specific.adb (Support_For_Libraries): New function,
+ returning None, used when there is no platform specific body for
+ MLib.Tgt.Specific.
+
+2007-10-15 Bob Duff <duff@adacore.com>
+
+ * sem_case.adb, sem_ch13.adb, lib-sort.adb: Replace use of Heap_Sort_A
+ (passing'Unrestricted_Access of nested subprograms to Sort) with use of
+ the generic Heap_Sort_G, in order to avoid trampolines.

+
+ * vx_stack_info.c: New file.
+
+ * i-forbla-unimplemented.ads: New file.
+
+ * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
+ for unsupported configurations; use it on VMS targets instead of the
+ real one.
+ (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
+ vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
+ used by VxWorks targets to have access to task-specific data and be
+ able to extract the stack boundaries for stack checking.
+ Use system-vms-ia64.ads on ivms.
+
+ * Make-lang.in: Update dependencies.
+
+ * sysdep.c (__gnat_get_stack_info): Move to a standalone file
+ (vx_stack_info.c).

+ (Process_Project_Tree_Phase_1): Set Success to False in case an error is
+ detected.
+
+ * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
+ True, compare both indexes in lower case.
+
+2007-10-15 Robert Dewar <dewar@adacore.com>
+
+ * rtsfind.adb: (Load_RTU): Turn off style checks for Load call
+
+2007-10-15 Gary Dismukes <dismukes@adacore.com>
+
+ * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
+ association for an access component, add an association with null as
+ the expression. Remove testing for array subtypes and the setting in
+ that case of Ctyp to the array component type, which prevented proper
+ inclusion of an association for null-initialized arrays. Collapse
+ condition that tests for array subtypes into just a test of
+ Is_Partially_Initialized_Type (which already covers arrays anyway).
+
+2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
+
+ * sem_ch12.adb: Minor code reformatting.
+ (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

+
+ * sem_ch4.adb: Minor code and comment reformatting.

+ allocator is a record with unknown discriminants or an array with
+ unknown range bounds, emit a detailed error message depending on the
+ compilation mode and whether the designated type is limited.
+
+2007-10-15 Tristan Gingold <gingold@adacore.com>
+
+ * system-vms-ia64.ads: New file.
+
+ * system-vms_64.ads: Minor comment fix.
+
+2007-10-15 Ed Schonberg <schonberg@adacore.com>
+
+ * sem_ch6.adb (Find_Corresponding_Spec): If the previous entity is a
+ body generated for a function with a controlling result that is a null
+ extension, discard the generated body in favor of the current explicit
+ one.
+
+2007-10-15 Ed Schonberg <schonberg@adacore.com>
+
+ * sem_disp.adb (Find_Controlling_Arg): Examine the call node before
+ examining its original form, to handle properly operator calls that
