--- Comment #13 from Martin Sebor  ---
I believe this now works correctly.  In C++ 11 mode and beyond the test case
from comment #6 is accepted and in C++ 98 mode it's rejected with the error
below.  Resolving as fixed.

$ cat t.C && gcc -S -Wall -Wextra -Wpedantic -std=c++98 t.C
template  class T {};
T t;
t.C:2:28: error: a cast to a type other than an integral or enumeration type
cannot appear in a constant-expression
 T t;
^
t.C:2:29: error: template argument 1 is invalid
 T t;
 ^

In C++11 mode we now accept these expressions. Not sure if we still want to

implement this old special case in C++98 mode.

DR 354 has been in state WP since October 2005.  Is that good enough to
unsuspend this issue?
