--- Comment #16 from Jonathan Wakely <redi at gcc dot gnu.org> ---
(In reply to Jonathan Wakely from comment #5)
> 27.4 [iostream.objects] paragraph 2
> The results of including <iostream> in a translation unit shall be as if
> <iostream> defined an instance of ios_base::Init with static storage
> duration. Similarly, the entire program shall behave as if there were at
> least one instance of ios_base::Init with static storage duration.

N.B. https://wg21.link/lwg2765 removed that last sentence, so we are no longer
required to run the stream initialization in all programs. Only in programs
which include <iostream> in at least one TU.
