--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Not a bug, because "no diagnostic is required".

A diagnostic is only required if the function template is instantiated, and we
do that.

G++ has been getting stricter about diagnosing errors with non-dependent names
and types in uninstantiated templates, so confirming as an enhancement request.
