g++ && imbue locale

[DM]

	Hello.

I'm having problem with locale in g++ on freebsd (5.1-RELEASE-p2). 

Following program should print 1,6 whereas it prints 1.6

#include <iostream>

using namespace std;

int main()
{

cout.imbue( locale("pl_PL.ISO_8859-2") );

cout << 1.6 << endl ;

return 0;
}

It refers to g++ 3.2.2 located in basesystem and port g++ 3.2.3 
(maybe to others too).

After comparing configure args in gcc 3.2.3 port and in linux debian, where
it works, I added --enable-clocale=generic.
So now I have:

g++32 -v

Reading specs from /usr/local/lib/gcc-lib/i386-portbld-freebsd5.1/3.2.3/specs
Configured with: ./..//gcc-3.2.3/configure --disable-nls --enable-clocale=generic --with-gxx-include-dir=/usr/local/lib/gcc-lib/i386-portbld-freebsd5.1/3.2.3/include/g++-v3 --with-system-zlib --includedir=/usr/local/lib/gcc-lib/i386-portbld-freebsd5.1/3.2.3/include/Java --disable-shared --prefix=/usr/local i386-portbld-freebsd5.1
Thread model: posix
gcc version 3.2.3

but it still does not work.

Does any one know how to "turn on" proper locale behaviour?

Thanks in advance.
