-------------------------------------------------------+--------------------
 When I create a class containing the SSE-intrinsic m128 in VC8 and try to
 serialize it with the boost serialization library the following static
 assert in type_with_alignment is triggered:

 {{{
 BOOST_STATIC_ASSERT(found % Align == 0);
 }}}

 Align is in my case 8 and the SSE-intrinsics are aligned to 16. Including
 m128 in BOOST_TT_ALIGNMENT_BASE_TYPES fixes the problem:

 {{{
 #define BOOST_TT_ALIGNMENT_BASE_TYPES BOOST_PP_TUPLE_TO_LIST( \
         13, ( \
         char, short, int, long,  ::boost::long_long_type, float, double,
 long double \
         , void*, function_ptr, member_ptr, member_function_ptr, __m128))
 }}}

 I guess that many other compilers have their own SSE-intrinsics defined so
 a more generic solution would of course be desirable.
