Thanks, Jens!

I will wait a day or two to see if there are other comments, but it
looks good to me.

A couple of nits in integer_traits_test.cpp:

*  Add "return 0;"

*  Probably be a good idea to add something to the effect:

     #ifdef NDEBUG
     #error This test makes no sense with NDEBUG defined
     #endif

*  Changed the first couple of lines of runtest to:

  typedef boost::integer_traits<T> traits;
  std::cout << "Checking " << type
            << "; min is " << traits::min()
            << ", max is " << traits::max() << std::endl;

integer_traits_test.cpp compiled and ran correctly with Metrowerks
Codewarrior 5.3.

But look at the results from Microsoft VC++ 6.0 SP3:

Checking bool; min is 0, max is 4294967295
Checking char; min is 0, max is 4294967295
Checking signed char; min is 0, max is 4294967295
Checking unsigned char; min is 0, max is 4294967295
Checking short; min is 0, max is 4294967295
Checking unsigned short; min is 0, max is 4294967295
Checking int; min is 0, max is 4294967295
Checking unsigned int; min is 0, max is 4294967295
Checking long; min is 0, max is 4294967295
Checking unsigned long; min is 0, max is 4294967295

Damn.  Microsofted again.  The compiler reported no errors or
warnings.
