Cutting another line or two: 
------------------- 
extern double sqrt (double) throw (); 
 
void foo(double& d, int n) 
{ 
  double e=0; 
  for(int i=0; i<n; i++); 
  for(int i=0; i<n; i++) e=1; 
  d = sqrt(e); 
 
  for(int i=0; i<n; i++); 
} 
----------------------------- 
g/x> /home/bangerth/bin/gcc-4.1-pre/bin/c++ -c x.cc -O3 -fPIC
