Yes you are absolutely right about objC, Ada, and D.

At the very least the personality routine, and all functions
that are calling __gnu_unwind_frame need that pragma.
in obj-C it is a macro CONTINUE_UNWINDING, that is fine.

In ada it is continue_unwind a function, that calls __gnu_unwind_frame,
and personality_body calling continue_unwind,
and the personality function itself.

In D it is CONTINUE_UNWINDING, a function.
scanLSDA, __gdc_personality, and gdc_personality itself.
