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
