--- Comment #6 from Yuri Victorovich <yuri at freebsd.org> ---
With both clang and gcc this line
> std::cout << std::wcout.getloc().name() << std::endl;
shows the locale in std::wcout defaults to "C" when it should default to the
current user's locale.

Without this std::wcout isn't usable from libraries because libraries have to
use the default state of std::wcout and it does not correspond to user's locale
without the top-level program setting it in std::wcout.
