This option changes the type of wchar_t to unsigned short.
Selecting this option modifies both the type of the defined type wchar_t in C and the type
of the native type wchar_t in C++. It also affects the values of WCHAR_MIN and WCHAR_MAX.
Default
The compiler assumes --wchar16 unless --wchar32 is explicitly specified.
