[boost] BGL regression

I cannot compile a (trivial) file containing just:

#include <boost/graph/graph_traits.hpp>

against current the anon-cvs version of boost cvs.
(Does it still lag the real repository?)

The error:

In file included from /home/aleem/boost/cvs/boost/graph/graph_traits.hpp:32,
                 from ../../../src/bgl/bgl.C:6:
/home/aleem/boost/cvs/boost/pending/ct_if.hpp:26: error: conflicting types for
   `struct boost::true_type'
/home/aleem/boost/cvs/boost/type_traits/detail/bool_trait_def.hpp:174: error: previous
   declaration as `typedef struct boost::integral_constant<bool, true>
   boost::true_type'
/home/aleem/boost/cvs/boost/pending/ct_if.hpp:27: error: conflicting types for
   `struct boost::false_type'
/home/aleem/boost/cvs/boost/type_traits/detail/bool_trait_def.hpp:175: error: previous
   declaration as `typedef struct boost::integral_constant<bool, false>
   boost::false_type'

suggests that the BGL is lagging behind changes made to the
Type Traits library.

Commenting out the line:

#include <boost/pending/ct_if.hpp>

allows compilation to proceed, but I am unsure what
repercussions this will have.

I'm compiling with g++ 3.3.2 on a Linux-Alpha machine 
running Debian unstable.

Interestingly, I don't see this problem on a PC running the RH8
flavour of linux. I don't know whether I've triggered a 64-bit problem
or one with the newer version of g++.

Hope that this report helps.
