allocator's access type.
(Resolve_Allocator): In the case of an allocator initialized by an
aggregate of a discriminated type, check that associations for any
access discriminants satisfy accessibility requirements by calling
Check_Allocator_Discrim_Accessibility.
(Resolve_Equality_Op): Handle comparisons of anonymous access to
subprogram types in the same fashion as other anonymous access types.
(Resolve_Concatenation_Arg): Remove initial character '\' in an error
message that is not a continuation message.
(Resolve_Type_Conversion): Add missing support for conversion to
interface type.
(Resolve_Actuals): Introduce a transient scope around the call if an
actual is a call to a function returning a limited type, because the
resulting value must be finalized after the call.
(Resolve_Actuals): If the call was given in prefix notations, check
whether an implicit 'Access reference or implicit dereference must be
added to make the actual conform to the controlling formal.

use of entity Exception_Occurrence if it is not available in the
target run-time.

* sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): When
concurrent types are declared within an Ada 2005 generic, build their
corresponding record types since they are needed for overriding-related
semantic checks.
(Analyze_Protected_Type): Rearrange and simplify code for testing that a
protected type does not implement a task interface or a nonlimited
interface.
(Analyze_Task_Type): Rearrange and simplify code for testing that a task
type does not implement a protected interface or a nonlimited interface.
(Single_Task_Declaration, Single_Protected_Declaration): use original
entity for variable declaration, to ensure that debugging information
is correcty generated.
(Analyze_Protected_Type, Analyze_Task_Type): Do not call expander
routines if the expander is not active.
(Analyze_Task_Body): Mark all handlers to stop optimization of local
raise, since special things happen for task exception handlers.

* sem_disp.adb (Check_Controlling_Formals): Add type retrieval for
concurrent types declared within a generic.
(Check_Dispatching_Operation): Do not emit warning about late interface
operations in the context of an instance.
(Check_Dispatching_Call): Remove restriction against calling a
dispatching operation with a limited controlling result.
(Check_Dispatching_Operation): Replace calls to Fill_DT_Entry and
Register_Interface_DT_Entry by calls to Register_Primitive.
(Check_Dispatching_Formals): Handle properly a function with a
controlling access result.

* sem_ch10.ads, sem_ch10.adb (Analyze_Compilation_Unit): Disable check
on obsolescent withed unit in case of limited-withed units.
(Analyze_Compilation_Unit): Add guard to code that removed an
instantiation from visibility, to prevent compiler aborts when
instantiation is abandoned early on.
(Install_Limited_Withed_Unit): Recognize a limited-with clause on the
current unit being analyzed, and Distinguish local incomplete types
from limited views of types declared elsewhere.
(Build_Limited_Views.Decorate_Tagged_Type): Add documentation
to state that the class-wide entity is shared by the limited-view
and the full-view.
(Analyze_With_Clause): Improve placement of flag for case of
unimplemented unit.
(Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a
manner similar to GNAT.Current_Exception. This is a violation of
restriction (No_Exception_Propagation), and also inhibits the
optimization of local raise to goto.
(Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,
and if so set Most_Recent_Exception_Used flag in Opt, and also check
for violation of restriction No_Exception_Propagation.
