templates - C++ type_traits for is static variable -

is there way in c++11 know if "const static" variable or no?
linked question
need modify function:

template<typename t> std::string to_string1(const t& value) {     std::ostringstream oss;     oss << value;     return oss.str(); } 

live demo http://coliru.stacked-crooked.com/a/ef91dff7d99aab29

if have "const int" variable compiler "undefined reference".
avoid want modify function (without & case):

template <typename t> std::stringtost(     typename std::conditional<          std::is_static<t>::value ,          const t,          const t&     >::type          std::ostringstream oss;         oss << value;         return oss.str(); ){ 

so i'll have 2 functions - 1 static const (with t value parameter), ant second other (with t& parameter)
