[Bug c++/15339] New: function call error

["MichaelLi8195 at hotmail dot com" <gcc-bugzilla@gcc.gnu.org>]

//*******mytest.hpp******* 
#ifndef MYTEST_H 
#define MYTEST_H 
#include <iostream> 
#include <string> 
template<typename T>    //declaration 
void fun(T val, const std::string seperator); //error, change to 
                                         //seperator = " " , then it works well

template<typename T>    //definition 
void fun(T val, const std::string seperator = " ") 
{ 
    std::cout<<val<<seperator<<std::endl; 
} 
#endif 

//***********test.cpp********* 
#include "mytest.hpp" 
int main() 
{ 
   fun(10); 
}

g++ test.cpp -o test
and reads "test.cpp:4:error: no matching function for call to `fun(int)'".
I think the function should be resolved from its definition not its 
declaration the first one it encountered. It means that although no default 
argument is provided in function declaration, as long as it has one default in 
the definition, it should also work well.
