>Description:
According to Josuttis "The C++ Standard Library" page 696 -- 697
passing an empty string as the name of the locale has a special
meaning. The default locale from the users's environment is used
(determined the environment variable LANG on Linux). But that does not work
with the current libstdc++ implementation. The value of LANG is 
ignored and the name of Locale1 in the program tgl is set to the empty
string which is wrong. Explicitly importing the German locale as in
Locale2 works though. 
>How-To-Repeat:
Source code tgl.C
#include <iostream>
#include <locale>

using namespace std;

int main()
{
    locale Locale1("");
    cout.imbue(Locale1);
    cout << Locale1.name() << endl;

    locale Locale2("de_DE");
    cout.imbue(Locale2);
    cout << Locale2.name() << endl;

}
