it with the non-limited view, which must be available. If the
called function is in the extended main unit then no action is
needed since the back-end handles this case.

* sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
aspect Implicit_Dereference can be inherited by a full view if
the partial view has no discriminants, because there is no way

I foolishly tested this with r241087 reverted. After that revision
default_stack_protect_guard is no longer called if the compiler defaults

there is some other way to enable the global guard.
