--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
N.B. I added other unguarded uses of the built-in to bits/locale_classes.tcc
and in that case it's used in C++98 too, so even std::is_same<>::value isn't
available (and I didn't want to use the old __are_same<>::__value trait).
I suppose we could add something like this to bits/c++config.h:
#if ! __has_builtin(__is_same)
// Assume the much older __is_same_as built-in is supported instead:
# define __is_same(T, U) __is_same_as(T, U)
#endif
but it sounds like it won't be needed now anyway. So I'll close this as WONTFIX
if that's OK.
