7.165 --wchar32

Changes the type of wchar_t to unsigned int.

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.
