+
+ * sem_ch3.adb (Analyze_Object_Declaration): If actual type is
+ private and distinct from nominal type in declaration, propagate
+ flags Is_Constr_Subt_For_U_Nominal and _UN_Aliased to full view
+ of private type.

+
+ * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
+ loop entry attribute for a while_loop we construct a function
+ that incorporates the expanded condition of the loop. The itypes
+ that may be generated in that expansion must carry the scope of
+ the constructed function for proper handling in gigi.

+
+ * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
+ dispatching call tp a subprogram with a class-wide precondition
+ occurrs in the same declarative part as the ancestor subprogram
+ being called, the`expression for the precondition has not been
+ analyzed yet. Such a call may appear, e.g. in an expression
+ function. In that case, the replacement of formals by actuals in
+ the call cannot use the formal entities of the subprogram being
+ called, and the occurrence of the formals in the expression must
+ be located by name (Chars fields) as would be done at a later
+ freeze point, when the expression is resolved in the context of
+ the subprogram itself.

+
+ * sem_prag.adb (Persistent_BSS): If an initialization is present
+ because of Initialize_Scalars or Normalize_Scalars, generate an
+ implicit pragma Suppress_Initialization to remove that, because
+ initialization is not allowed for these variables. Other
+ initializations remain illegal.
+

+
+ * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
+ conversions, apply the recursive call to the Original_Node of
+ the expression Exp rather than the Expression of the
+ Original_Node, in the case where Exp has been rewritten;
+ otherwise, when Original_Node is the same as Exp, apply the
+ recursive call to the Expression.
+ (Check_Initialization): Revise condition for special check on
+ type conversions of limited function calls to test Original_Node
+ (avoiding spurious errors on expanded unchecked conversions
+ applied to build-in-place dispatching calls).

+
+ * sem_ch13.adb (Is_Null_Array): New function, used to detect the
+ null array case; used to warn about uncheckedly converting to a
+ zero-sized array. It is unfortunate that we can't just check
+ the size, and warn on all cases of converting from a
+ nonzero-sized type to a zero-sized one. That's because "0" means
+ two different things: "size is zero" and "size is unknown".
+ Until we fix that design flaw, we need this more targeted fix.
