[boost] MSVC++ 6.0 compiler errors with 1.30.0 (mostly lexical_cast.hpp)

I downloaded 1.30.0 and tried to build my project. I got a few errors 
that seem to be in boost, primarily in lexical_cast. Also, 
weak_ptr.hpp uses bad_weak_ptr without including 
boost/detail/shared_count.hpp anywhere. I can fix that by
including it in my code.

These are the warnings in lexical_cast.hpp. Because I treat 
warnings as errors, these pretty much keep me from using this
version of boost.
