Force english locale on Win32

[Саша Иваненко <kitovyj mail ru>]

Hi All.

I use gtkmm for my GUI app on Win32 XP platform. Native locale for my system is russian. Problem is I cant force gtkmm to speak english! I have searched various forums, but nothing helps. I tried to sel locale at program startup using these functions:

putenv("LANG=en_US.UTF8");
putenv("LANGUAGE=en_US"); 
putenv("LC_ALL=en_US");
setlocale(LC_ALL, "C");

But gtkmm still print russian text on the standard dialog buttons etcetera.
Please help to force english locale to gtkmm. 

Regards,
Alex Ivanenko
