The latest does not give a syntax error, but it does give a warning:

example.i:18: Warning(503): Can't wrap 'friendfun<(X)>' unless renamed 
to a valid identifier.

which strikes me as unwarranted. I suggest you filter the warning as 
below. Can you add this testcase into the bug tracker?

%warnfilter(503) friendfun;

%{
template<class X> void friendfun (X arg){};
%}

%inline %{

template<class X> class Test{
   int counter;
public:
   Test(int init){
     counter=init;
   };
   friend void friendfun <X> (X arg);
};
%}

%template(TestInt) Test<int>;
