Thanks! Above didn't work, but I tweaked a little by using namespace and 
it compiles fine. Also, the game ran fine. I added looks like this:

=============================================
#if (__FreeBSD_version < 500029)
#include <cwchar>
namespace std
{
	typedef basic_string <wchar_t> wstring;
}
#endif
=============================================

Cheers,
Mezz
