>Description:
	
The fill and fill_n functions are missing when compiled with -fno-implicit-template,
leading to an error at link time.

This is similar to bug 8172, in which I reported a missing operator+ for strings.
>How-To-Repeat:
	
Program text:
#include <algorithm>
using namespace std;
int main() {
  double x[10];
  fill_n( x, 10, 1.0 );
  fill( x, x+10, 2.0 );
  return 0;
}

Compile command:
g++ -fno-implicit-templates  nofill.cc

 This is user confusion.

 Which matches the documented behaviour.

 The above tells g++ not to implicitly instantiate the required
 definitions.  Which means you *ought* to manually provide them --
 usually through explicit instantiation.  
 
 The simple way fo fix this is: don't do that.
