Incomplete C++11 "alignas" implementation

Hi,

icc 15.0 gives me a warning when compiling the following code:

template
using type alignas(64) = T;

warning #3463: alignas does not apply here
using type alignas(64) = T;

If I understand correctly my code is correct, and indeed GCC and Clang compile it properly without warnings. Is this a known issue with icc? Can I expect a fix in future versions?

Thanks,
Simon
