--- Comment #13 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-04-26 10:03:41 UTC --- Thanks. Thus, since the original issue boils down to a C++ front-end issue only, I guess we have to wait for Jason' opinion whether we can avoid adding a builtin and go the way proposed by Gaby or not. I would really like to see this fixed for 4.6.1 too, I hope we can figure out something suited, minimally invasive and/or restricted to the C++0x codepath...
