[boost] [serialization] MSVC8 warning flood (widened size_t)

Hi,

when using the Boost.Serialization library with MSVC8 I get flooded by 
(about thousand lines of) warning messages due to the fact that size_t 
has been widened (and there are just very few small classes in my 
project that use serialization).

It's especially annoying because warnings about truncating conversions 
are quite useful, in general (I wouldn't want to disable them 
permanently, that is).

Boost.Serialization:

  [ collections_save_impl.hpp:36 ] "possible loss of data converting...".
     unsigned int <var> = <size_t expression>
        
  [ detail/oserializer.hpp:479 ] "possible loss of data converting..".
     int <var> = <size_t expression>

- I guess there are some more but these are the ones the compiler gets 
to see in my project (that's also why I didn't post a patch).

Boost.TypeTraits (used by Boost.Serialization):

  [ is_abstract.hpp:81 ] BOOST_STATIC_ASSERT(sizeof(expression))"
         "forcing value to bool"

Just in case it isn't on anyone's todo-list, yet...

Greetings,

Tobias
