Any help is appreciated, Thanks.

CODE:

using namespace std;

os << "Our vector of vectors" << endl;
for(vector< vector<T> >::iterator ite = vec.begin(); ite!=

I can't see anything wrong on the 15th line (the above is the 13th) but
try using
for (typename vector< vector<T> >::iterator ite = ...

Hi Erik, and many thanks for your input.

Two things:

- How did you figure out that by adding "typename" the error would
go?...by the way the error message is not appearing anymore...

Because it is required by the standard. So it is Microsofts compiler
that is broken in this respect, not gcc.

-...however, now I am getting the following error (it looks like it
came from a deeper part of the compiling process):
$ g++ -Weffc++ -Wall -Wctor-dtor-privacy -Wold-style-cast -
Woverloaded-virtual -o kk kk.cpp
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):
(.text+0xab): undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status

This is a linker error. You are more likely to get help in a gcc
newsgroup, but most likely you forgot to include a library.

Does anybody know if the compiler g++ 3.4.4 is broken?

Yes it is - in the strictest sense of the word. But not here.
