implicit typename is deprecated

Oh man, Stanford just updated it's gcc and gcc libraries - and now my precious code won't compile. Seems like it'll be a nightmare to sort out. I made some headway adding 'using namespace std;' right after the included files. But what is this 'implicit typename is deprecated'. I found a hint here. When getting the type of object T inside of container using value_type, e.g., valarray::value_type, the term 'typename' needs to go in front of the declaration, i.e., typename valarray::value_type. So, if before I had:

copy(&data[0],&data[0]+data.size(),ostream_iterator< valarray::value_type >(s," "));

Now I should have:

copy(&data[0],&data[0]+data.size(),ostream_iterator< typename valarray::value_type >(s," "));

Hmmm, this is also a problem with iterators. You need to preface iterators with typename. Note that use of the term 'typename' is for when one is using templates.
