Hmm, now it looks a little different than yesterday. Ok, the following
four lines make it work.

     BOOST_STATIC_CONSTANT(T, next_value = (N + 1));
     BOOST_STATIC_CONSTANT(T, prior_value = (N - 1));
     typedef integral_c<T, N + 1> next;
     typedef integral_c<T, N - 1> prior;

Note the use of N+1 and N-1 instead of next_value and prior_value
in the typedef.

If I apply the fix mentioned above the thread library compiles for me.
