I believe this is a compiler/STL problem. Here is snippet of offending
code:

template<typename T>
struct print_log_value {
    void    operator()( std::ostream& ostr, T const& t )
    {
        // Show all possibly significant digits (for example, 17 for 64-bit
double).
        if( std::numeric_limits<T>::is_specialized &&
std::numeric_limits<T>::radix == 2 )
            ostr.precision(2 + std::numeric_limits<T>::digits * 301/1000);

        ostr << t; // by default print the value
    }
};

If I try to print C literal this function is instantiated with char [N]. And
if fails to instantiate std::numeric_limits<char [N]>.

Shouldn't numeric_limits work for any type?
