Summary: setlocale fails with c++ cin and cout

Initial Comment:
I am working with w32api 1.2. I am using the setlocale 
function (from locale.h) to change the decimal_point 
behavior of cin and cout in C++. This doensn't work. 
However, on Linux (suse 7.3), I have setlocale working 
with cin and cout.

After some testing with w32api, I found that setlocale 
only works for scanf and printf functions. In 
addition, language-strings which setlocale accepts are 
different for Linux and w32api. With Linux, "en_US" 
and "nl_NL" are accepted. With w32api, these are not 
accepted, but "nld" and "usa" are accepted. 

Executing the following code shows the problem:
setlocale(LC_ALL, "nld");
cout << "after nld  :  setlocale = " << setlocale
(LC_ALL, NULL) << endl;
cout << "cout:  x= " << (float)1234/3 << endl; 
printf("printf: x= %f\n", (float)1234/3); 

setlocale(LC_ALL, "usa");
cout << "after usa  :  setlocale = " << setlocale
(LC_ALL, NULL) << endl;
cout << "cout:  x= " << (float)1234/3 << endl; 
printf("printf: x= %f\n", (float)1234/3); 


How can I get it working? 

Thanks in advance, Alexander

In libstdc++, only C-locale is currently supported under 
mingw in iostream classes. setlocale changes the setting of 
the current active locale.  It doesn't affect the static  
global C-locale.

The language strings accepted by setlocale are outside 
mingw's control.  They are determined by the MS runtime, 
which supplies setlocale.
