--- Comment #2 from Augusto Righetto  ---
Hi Paolo,

I apologize for filling a bug for an unimplemented feature.
However, if you take a look at
http://gcc.gnu.org/gcc-4.8/cxx0x_status.html, you'll see that "Alignment
support" is marked as available on GCC 4.8.
Having two different tables to track down features is confusing.

Thanks,

Augusto
