Is this already known?

quartz% cat throw.cc
#include <stdexcept>

using namespace std;

void func(void)
{
  throw runtime_error("in func()");
}
quartz% cat catch.cc
#include <iostream>
#include <stdexcept>

using namespace std;

void func(void);

int main()
{
  try {
    func();
    return 0;
  }
  catch(const runtime_error& e) {
    cerr<<"runtime error: "<<e.what()<<endl;
    return 1;
  }
}
quartz% g++ -shared -o libthrow.so throw.cc
quartz% g++ catch.cc -o prog -L. -Wl,-R. -lthrow
quartz% g++ -v
Using builtin specs.

(both NetBSD/i386, one from just before the gcc3 switch, the other from after)
Do I new flags?
