This bug is related to c++/2405, which has been closed already.
Indeed, the example given there seems to be fixed.  But something
similar can be easily triggered with the GCC-3.0 release by 
this example:
 
#include <iostream>
#include <vector>
#include <utility>
using namespace std;
using namespace std::rel_ops;

int main(void)
{
    vector<int> iv;
    iv.push_back(0);
    iv.push_back(1);
    //... 
    for (vector<int>::iterator i=iv.begin(); i!=iv.end(); ++i) { }
}


Q: Does this qulify as a regression?  After all in gcc-2.95 there was no
such thing as namespace rel_ops and the applications worked fine.
