So I'm trying to get some code that is written for gcc to compile on Visual Studio 2008. I have a problem that I have narrowed down to this:

class value_t
{
public:
  typedef std::deque<value_t>         sequence_t;
  typedef sequence_t::iterator        iterator;
};

This code fails:

1>cpptest.cpp
1>c:\program files\microsoft visual studio 9.0\vc\include\deque(518) : error C2027: use of undefined type 'value_t'
1>        c:\temp\cpptest\cpptest.cpp(10) : see declaration of 'value_t'
1>        c:\temp\cpptest\cpptest.cpp(13) : see reference to class template instantiation 'std::deque<_Ty>' being compiled
1>        with
1>        [
1>            _Ty=value_t
1>        ]
1>c:\program files\microsoft visual studio 9.0\vc\include\deque(518) : error C2027: use of undefined type 'value_t'
1>        c:\temp\cpptest\cpptest.cpp(10) : see declaration of 'value_t'

However when I try this with std::vector, it compiles fine:

class value_t
{
public:
  typedef std::vector<value_t>        sequence_t;
  typedef sequence_t::iterator        iterator;
};

What's wrong? I have tried adding 'typename' everywhere I can think of, but at this point in time I'm thinking it's just a bug in the Dinkumware STL. Can anyone explain what's happening, and/or offer a solution? Thanks.
