--- Comment #4 from Paul Eggert <eggert at gnu dot org> ---
> main() has an implicit return 0.
That's irrelevant to the purpose of the warning. The warning is there to catch
the common typo of a function containing a return statement even though it is
declared 'noreturn'. But there is no typo here.
As it stands now, the 'main' function cannot have __attribute__
((__noreturn__)), even when 'main' is designed to never return. This
restriction makes no sense from the user's point of view.
