Well let UNICODE aside. wchar_t is a wide character type existing in
*all* machines. It belongs to the C/C++ standards. In C90 wchar_t is a
typedef defined in stddef.h. In C++98 it is a *built in* type (and in
all machines using UNICODE, wchar_t is usually UNICODE).

I see no reason why "activate" or "deactivate" wide character support
using "compilation under condition". If your code needs wide character
support so as to work in some platforms, use wchar_t in the first place
(something bad, from all the compilers i have seen, wcout doesn't exist
in MINGW's <iostream> and probably in GCC itself).


Forget all the Win32 bad programming styles. :)
