// BOOST_DECL: Certain compilers for Microsoft operating systems require
// non-standard class and function decoration if dynamic load library linking
// is desired. BOOST_DECL supplies that decoration, defaulting to a nul string
// so that it is harmless when not required. Boost does not encourage the use
// of BOOST_DECL - it is non-standard and to be avoided if practical to do so.
// BOOST_DECL_EXPORTS: User defined, BOOST_DECL_EXPORTS causes BOOST_DECL to
// be defined as __declspec(dllexport) rather than __declspec(dllimport).
// is desired. BOOST_DECL supplies that decoration. Boost does not require
// use of BOOST_DECL - it is non-standard and to be avoided if practical to do
// so. Even compilers requiring it for DLL's only require it in certain cases.

// BOOST_DECL_EXPORTS: User defined, usually via command line or IDE,
// it causes BOOST_DECL to be defined as __declspec(dllexport).
//
// BOOST_DECL_IMPORTS: User defined, usually via command line or IDE,
// it causes BOOST_DECL to be defined as __declspec(dllimport).
//
// If neither BOOST_DECL_EXPORTS nor BOOST_DECL_IMPORTS is defined, or if
// the compiler does not require __declspec() decoration, BOOST_DECL is
// defined as a null string.
// BOOST_MSVC6_MEMBER_TEMPLATES: Microsoft Visual C++ 6.0 has enough member
// template idiosyncrasies (being polite) that BOOST_NO_MEMBER_TEMPLATES is
