cerr not defined

[shane@shaneroberts.com]

Bjorn,
thank you, things are beginning to become clear.

It would appear that there was an error in the Stroustrup book
where "std::" was left off "cerr" so that it should have been:
std::cerr << P << ' ' << P2 << '\n';

for emitting the error message.

This would have placed cerr in the std namespace which is 
where<fstream> places it as opposed to <fstream.h>.

Since I am new to g++ and C++ can anyone clue me into when
C++ standards changed, and g++ header files were 
relocated/changed?
I just need to get my bearings so I know how to distinquish between
"old" and "new".

Thanks,
Shane
