MinGW-w64 GCC supports the -municode switch, which I believe is what is
needed here:

But I can't test this right now.
Anyways, using _tmain and the whole TCHAR business is silly. Don't use it
in any real code, please. Instead either use char encoded as UTF-8
internally, converting when you call the Windows API, or use wchar_t
directly. Just my 2c ;-)
