STL deque question

I'm using Microsoft VC++ 5.0, starting to play around with STL. I'm trying to perform the following operation on a deque:

myDeque.insert (iterator it, InputIterator first, InputIterator last);

For some reason, no matter what I do, the compiler tries to use the OTHER version of insert:

myDeque.insert (iterator it, size_type n, const T& x);

Of course, it tells me it doesn't know how to convert an input iterator into an unsigned int. Well, DUH. I've tried const char *, casting to vector<char>::const_iterator, even copied the whole character array into a vector and used myVec.begin () and myVec.end (). NOTHING WORKS!!

I'm very frustrated. Please help!

(trying to convince my team to stop writing their own container classes, but if this is how the "standard" is implemented by Microsoft, the hard way might be BETTER!)
