--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
There is no difference between functions f() and g() in comment #0.  The source
code in both is equivalent (and the latter is frequently preferred to the
former) and the emitted object code is identical.  So irrespective of whether
or not both were considered in the implementation of the warning, I can't think
of a justification for diagnosing only one and not the other that would be
helpful to users.  (If there is one, what is it?)
