--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
With 4.9 and earlier you only get the error once:

access.cc: In instantiation of ‘struct Detect<X>’:
access.cc:14:10:   required from here
access.cc:12:28: error: ‘using type = long int’ is private
 class X { using type = long; };
                            ^
access.cc:10:34: error: within this context
   { using type = typename T::type; };
                                  ^

So the repeated diagnostics is a regression, but it would be better not to
issue any diagnostics at all.
