Since Intel C++ on Windows is supposed to be compatible with Visual C++
I think this should be testing _NATIVE_WCHAR_T_DEFINED and not
_WCHAR_T_DEFINED. VC++ defines the latter if wchar_t is an intrinsic
type *or* a type alias but it defines the former only if wchar_t is an
intrinsic type.

I couldn't find any detailed documentation for Intel C++ online so I
don't know if it is exactly compatible in this respect.
