--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Things in C typically return the address of a string in memory as that string.
Only if your function actually returns an array of bytes (not the address of
such a thing) does this text (in 3.2.4 in the spec) apply.

It isn't clear to me what should happen for Ada here, what the Ada ABI for this
is, irrespective of what the Power implementation of that is!
