Here's a simpler test, which should return 1:

#include <locale>

int main()
{
    return isspace(L' ', std::locale());
}

if that works, how about this, which should also return 1:

#include <locale>
#include <sstream>
#include <string>

int main()
{
    std::wstring s(L" ");
    std::wistringstream ss;
    return isspace(s[0], ss.getloc());
}
