incompatabilities found with GNU gcc STL code

I have some C++ code that uses STL heavily, and it compiles correctly on GNU gcc 4.2, 4.3, 4.4, and 4.5 on Ubuntu linux.
 It also compiles correctly on Microsoft MSVC 2008.

However, I cannot get it to compile using the 4.8.0 Momentics Tools (build # 201105051724).

I haven't figured out how to select the STL library to use.
My best guess so far is:
from Project Properties-->C/C++ Build-->Settings:
choose the Tool Settings tab, and select Target:
then choose the Runtime from the combo box.
I have tried both C++ GNU with exceptions, and C++ Dinkum with exceptions,
but I still get errors regarding my iterators.

The errors are mostly one of:
error: no type named 'iterator_category' in class <such and such>
error: no type named 'value_type' in class <such and such>
error: no type named 'difference_type' in class <such and such>
error: no type named 'pointer' in class <such and such>
error: no type named 'reference' in class <such and such>

Since Momentics is built on gcc, and I can compile this code under linux using the above listed versions, I believe my 
code is fine, and there must be some configuration item I can change to get my code to build.

I welcome any suggestions.
Thanks

Can you post an example?

Re: incompatabilities found with GNU gcc STL code

I have made a code modification that satisfies the compiler, so I can proceed.

However, I would still like to know if there is a configuration option that I could have set to be able to compile the 
original code.

My modification is to add the missing types at the start of my iterator class declaration:

// this is a nested class within my own templated container
 class iterator
 {
   public:
     typedef T value_type;
     typedef int difference_type;
     typedef T * pointer;
     typedef T & reference;
     typedef std::random_access_iterator_tag iterator_category;

   public:
      iterator ()  {}

Re: incompatabilities found with GNU gcc STL code

I forgot to mention that I also added the standard header file for iterators:
#include <iterator>

Return

The text you entered is not a valid object ID
More Information
Object IDs begin with an object prefix and end with a number. For example, if you enter
artf2345
the application will jump directly to an artifact with the ID artf2345. Some valid object prefixes are:
artf	for an artifact
doc	for a document
page	for a project page
topc	for a discussion topic
wiki	for a wiki page
