I read SUS v3 and there is no hint on multi-wchar anything,
so for unix systems you are right, wint_t == wchar_t.
Seems stories how Windows and Java operate have affected me too much.
Then I browsed MSDN:
http://msdn.microsoft.com/en-us/library/dtxesf6k.aspx
and they seem to strongly hint that wchar_t == 16 bits and
UTF-16 is used internally.
Probably some Windows developer should look into it
and decide if there is a #ifdef WIN32 branch needed.
