[cfe-commits] [patch] please review: is_standard_layout

[Howard Hinnant]

I'm trying to enable __has_feature(is_standard_layout).  But I really have no idea what I'm doing in here.  Just copying what is already there.

I've briefly tested __is_standard_layout(T), and note that it has 17 tests in type-traits.cpp.

Thanks,
Howard
