to_simple_string and Windows?

Hi. I have used the boost::date_time library in Linux with no problems, but the same can not be said of my experience with it in Windows... My current pain in Windows is with the "to_simple_string" method used to convert a boost::date_time value to guess what, a string. This works fine in Linux, but not in stupid Windows. The following line just borks: std::cout << to_simple_string(date(2003,4,30)) << std::endl; Any little unknown configuration tricks etc. I need to be aware of here? Has anyone used the "to_simple_string" method without problems in Windows? I'll appreciate any help in this regard. Greetings, A. [Non-text portions of this message have been removed]
