--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> ---
The patch doesn't affect the testcases, because there the templates are sti=
ll
considered equivalent.

Though now I notice that the suggested resolution of DR1286 only considers
template equivalence in the context of comparing template arguments; it isn=
't
saying that they're interchangeable in all contexts.  So perhaps we should =
stop
using that equivalence in this case.=
