While we're at it, the following for C++ Builder would be useful:

#ifdef __BORLANDC__
// C++ builder 4:
#   define BOOST_NO_MEMBER_TEMPLATE_FRIENDS
#   if defined BOOST_DECL_EXPORTS
#     define BOOST_DECL __declspec(dllexport)
#   else
#     define BOOST_DECL __declspec(dllimport)
#   endif
#endif

Thanks,

- John.
