Does djgpp support explicit instatation of template functions ? 
This program produces these errors : 

C:\C++\C++PrimerPlus\basic.cpp: In function `int main()':
C:\C++\C++PrimerPlus\basic.cpp:9: parse error before `template'

I have no idea what the parse error could possibly be.  

My books say I can use : 
template  swap <int>(int, int);   
but none of the many books I have give even the slightest hint of a clue
as to where it goes, so I have taken a wild guess. Perhaps it doesn't
matter. I have tried it everywhere but it never works. What is the right
place to put that line ? Why doesn't it work ? 


 #include <iostream>
    using namespace std;
      
template <typename any>
void swap (any &, any &);//template for everything but int


int main()
{   template  swap <int>(int, int);//explicit instantiation for int     
    int first= 10;
    int second=20;
    swap(first, second);   
    
    return 0;
 } 
 
  
    template <typename any>       
    void swap (any &x, any &y)
    {   any temp;
        temp = x;
        x=y;
        y=temp;
     
    }
         


Errors: 

C:\C++\C++PrimerPlus\swap.cpp: In function `int main()':
C:\C++\C++PrimerPlus\swap.cpp:9: parse error before `template'
