[Bug c++/19725] New: missing std::wstring support

[hundertmarck at boehme-weihs dot de]

I want to compile c++ source that uses std::wstring but std::wstring is
undeclared. So I greped around an found that the specialization in stringfwd.h
needs to declare _GLIBCXX_USE_WCHAR_T. After this define, the compiler prints
out many errors about missing declarations to some w-functions.

The following source should be compiled: <END_OF_SOURCE
#include <stdio.h>
#include <wchar.h>
#include <string>
using namespace std;

int main()
{
        wstring ws( L"TEST WIDE CHARACTER STRING\n" );
        printf( "%S\n", ws.c_str() );
        return 0;
}
END_OF_SOURCE

I'm using gcc-3.4.3 with gcc-3.4.3-branch-update-20050110.patch.

# gcc -v

gcc version 3.4.4 20050111 (prerelease)

# /usr/local/bin/ld -v
GNU ld version 2.14 20030612

I have tried to compile the same code with the gcc-3.4.3 build by the HP-UX
Porting Centre but it fails with the same behavior.

Before that I tried the same code with gcc-3.1. It fails with the same behavior too.

Do I anything wrong?
Is that really a Bug? => exists a workaround?

Thanks ahead
