I also found the same problem with a friends fedora core 4 with gcc 4.

I have attached a cpp file that (I believe) should compile (and does on
Borland c++).  It is the copy at the end that causes a problem - the
while loop is simply doing the same as what the copy should do (just to
show I did the operator<< properly).  Copy works for other cases (ints,
floats, etc) and even for my own structs too.  I'm just not sure why it
complains about the operator<< function for a std::pair.
