This works find in Dev Studio and Codewarrior but does not compile
GCC4:

template <class T>
void SerializeVector(RArchive &ar, vector<T>& v)

for (vector<T>::iterator i = v.begin(); i != v.end(); i++)
SerializeVar(ar, *i);
}

I get "error: expected `;' before 'i'". Even if I just have
"vector<T>::iterator i ". Why would changing compilers cause this
problem? Am I doing something wrong? How do I fix?

g++4 is the more conformant compiler on this point. Your for-loop
should read:

for ( typename vector<T>::iterator i = v.begin(); i != v.end(); ++i)

Can you say where I can read g++4 information about this topic?

I would like to learn it's behavior about the iterators.

You should ask in a g++ newsgroup, two of which are listed in this FAQ:
