--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
As noted in the discussion, the GCC behavior in the Description of this bug
matches the intent (if not the words) of the C90 standard.  Any change here
would only serve to break existing programs that rely on it.  Closing as
invalid.  (Adding a test to exercise this behavior might be worthwhile.)
