>Description:
I cann't use wcout and wprintf to print wchat_t string in gcc-3.2 and gcc-3.1,but I can use wcout to print wchar_t* in gcc-3.0.4,that's why?

the following lines are the source code:
#include <iostream>

using namespace std;

//#define _GLIBCPP_USE_WCHAR_T

int main(int argc, char** argv)
{
	const wchar_t* src  = L"hello ÕÅ»¹±ö´ø·ÖÊý¶¯";
	wcout << "src: " << src << endl;	

}

#include <stdio.h>
#include <wchar.h>
//#include <stdarg.h>

int main(int argc, char** argv)
{
	const wchar_t* src  = L"hello ÕÅ»¹±ö´ø·ÖÊý¶¯";
	wprintf(L"wstring is : %s \n",src);
		
	return 0;
}
