-------------------------------------+--------------------------------------
 There are a number of warnings that come up with Boost.Serialization in
 the assertions that deal with checking the number of bytes against the
 maximum value for an std::streamsize. The problem is that 'count' is a
 size_t (unsigned) while std::streamsize is signed.

 The attached patch goes around it by converting count to a std::streamsize
 in one place and the other converting the max of a std::streamsize to an
 std::size_t. I'm not sure if this is the right fix, would be good to know
 one way or another.
