Comment:

 /RTCc yields non-conformant behavior.  The behavior of the following
 program is well-defined (technically implementation defined since
 sizeof(short) is implementation defined) according to the C++ standard.
 In most
 implementations it will print 1.

 {{{
 #include <iostream>

 int main() {
     unsigned int i = 65537;
     unsigned short s = static_cast<unsigned short>(i);
     std::cout << s << std::endl;
 }
 }}}
