I don't know if it was a macro problem or not. But based on what you said,
I tried to rewrite the functions. With this function, the compiler is
not happy (E2451 "Undefined symbol 'Traits'"):

  template<class T, class Traits> inline
  interval<T, Traits> interval<T, Traits>::whole()
  {
    const T& inf = checking::inf();
    return interval<T, Traits>(-inf, inf, true);
  }

But with this one ('Traits' is replaced by 'Policies'), it compiles fine:

  template<class T, class Policies> inline
  interval<T, Policies> interval<T, Policies>::whole()
  {
    const T& inf = checking::inf();
    return interval<T, Policies>(-inf, inf, true);
  }

So this problem is now fixed (but I'm quite surprised that 'Traits' should
not be used). There is another problem (E2188 "Expression syntax") with
the line 81 of 'interval/arith2.hpp' which is:

  using interval_lib::detail::pow_aux;

But I didn't find a solution by changing names. I would also like to say
that this code compiles just fine with GCC, Intel CC, Sun CC (and Borland
CC in non-release mode!).

There are also a lot of problems with Boost Test framework since E2316
"'__strcmp__' is not a member of 'std'" (I suppose there is a '#define
strcmp __strcmp__' somewhere).

So I think I just want to forget the release mode for this compiler...
