64 bit compile warning/error for boost::format

[nobody]

We are using MS Visual Studio 2005.  Compiling for 64
bit Windos.  We are compiling with warning level 4 and
warnings == error.

We're using boost 1.33.1 and STLPort 5.0.0

boost::format generates a possible loss of data
conversion warning when compiling alt_sstream_impl.hpp
