--- Comment #3 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
This is the error that should be emitted (modulo the argument type being
_Iterator)

devvm2772:6>./cc1plus -fmodule-header -quiet b_a.H
In file included from b_a.H:1:
b.h:10:69: error: call to 'static void _Iterator<_Const>::mover(const int&)'
uses the default argument for parameter 1, which is not yet defined
   10 |   friend void move (const _Iterator &arg) noexcept (noexcept (mover
()))
