To: gcc-bugs
When running "g++ -std=c++0x" on the following two lines,
std::wstring s;
s = std::wstring(L"hello world");
the loader complains that there is an
undefined reference to `std::basic_string<wchar_t, std::char_traits<wchar_t>,
std::allocator<wchar_t> >::operator=(std::basic_string<wchar_t,
std::char_traits<wchar_t>, std::allocator<wchar_t> >&&)'
However, if the file x86_64-unknown-linux-gnu/libstdc++-v3/src/wstring-inst.o
in the gcc 4.5.0 build directory is added to the loader line, then there is
no problem.
