//
// When targeting MSVC compatibility (clang-cl), wchar_t is only a distinct intrinsic
// type when _NATIVE_WCHAR_T_DEFINED is defined (i.e. /Zc:wchar_t). Under /Zc:wchar_t-,
// wchar_t is an alias for unsigned short, so mirror visualc.hpp here to avoid emitting a
// duplicate wchar_t specialization that redefines the unsigned short one.
