The following code compiles fine with MSVC10 and gcc:

#include <boost/tokenizer.hpp>

template <typename char_type_t>
struct S

{
    typedef boost::char_separator<char_type_t> sep_type_t;
    typedef boost::tokenizer<sep_type_t> tokenizer_t;

    S(const std::string& messageString, const std::string& separator)
        : sep_(separator.c_str()),
        t_(messageString, sep_),
        i_(t_.begin()) {}

    sep_type_t sep_;
    tokenizer_t t_;
    typename tokenizer_t::iterator i_;
};

int main()
{
    S<char> s("foo bar", " ");
}
