--- Comment #10 from Martin Sebor <msebor at gcc dot gnu.org> ---
The purpose of the internal_p flag documented in the attr_access class is more
general than to tell a VLA-like argument from an ordinary array/pointer form
("Set for an attribute added internally rather than by an explicit
declaration") so tying the two together would be fragile. I expect using
internal_p directly as Siddhesh suggests will probably work now but I would
recommend using the vla_bounds() member function instead in case things change
in the future.
