--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, with current gcc the diagnostic is:
$ /usr/local/bin/g++ -c -Wall -Wextra -pedantic 47342.cc
47342.cc:26:14: error: invalid use of incomplete type ‘struct X<Y<T> >’
X< Y<T> >::f() // xxx
^
47342.cc:2:8: note: declaration of ‘struct X<Y<T> >’
struct X : T
^
$
...which could still be improved.
