* 2000-06-27 Rework for better MSVC and BCC co-operation

#include <iostream>

#include <boost/integer_traits.hpp>

// use int64_t instead of long long for better portability

#include <boost/cstdint.hpp>

#include <boost/core/lightweight_test.hpp>

* General portability note:

* MSVC mis-compiles explicit function template instantiations.

* For example, f<A>() and f<B>() are both compiled to call f<A>().

* BCC is unable to implicitly convert a "const char *" to a std::string

* when using explicit function template instantiations.

* Therefore, avoid explicit function template instantiations.
