Thanks, just compiling with /Zc:wchar_t- didn't help in my case, however
I noticed that one message in the above thread indicated to add

template<> _CRTIMP2 std::size_t __cdecl char_traits<unsigned
short>::length(unsigned short const*);

This brought the linker errors down to just one, so in a similar
fashion, I added:

template<> __thiscall std::allocator<unsigned short>::allocator(void);

Which enabled me to build my project successfully.
