[Boost-users] Serialization - 'size_t' to 'std::streamsize' error

Ok....this is really confusing.

I successfully created a small test project several months ago using the
Boost Serialization library to serialize some binary data.  I am now
attempting to add binary serialization to a production project, and I
receive a bunch of compiler warnings.

I can still compile and execute the test application with no warnings or
errors.

I am using VS2005 with boost 1.34.1

I have included the first few compiler warnings below...

1>C:\Program
Files\boost\boost_1_34_1\boost/archive/basic_binary_oprimitive.hpp(136) :
warning C4267: 'argument' : conversion from 'size_t' to 'std::streamsize',
