It's GCC that does that.  However, it also puts them in namespace std,
(or, at least, acts as if it does) so there's little problem in practice.

Only if you were taking advantage of the fact that GCC dumps everything
into the global namespace.  (I've seen a number of posts where people
have done that - there's an awful lot of broken C++ code out there...)

What you have above doesn't work in Borland C++ 5.5.  But, of course,
it will work if you put the using directive after the #include.
The best thing to do is to go through and fix your code by hand, even
if that just means putting a using directive (in the correct place)
in each file.
