If you want the largest native integer, though not 100% portable to weird archs, this should work in x86/x64 and most others:

typedef boost::int_t::fast fastint_t;

Why not just use the standard {u}intptr_t or {u}intmax_t typedef in this case?

For intptr_t, this message comes to mind: http://lists.boost.org/Archives/boost/2005/09/94158.php And intmax_t is the wrong choice on 32-bit systems that provide a 64-bit type.
