Subject: [boost] Stupid Win32 DLL vs Static question

I'm working on prototype build scripts.  In testing, I ran into static 
linking problems.  In boost/config.hpp we now define this:

#   if defined BOOST_DECL_EXPORTS
#     define BOOST_DECL __declspec(dllexport)
#   else
#     define BOOST_DECL __declspec(dllimport)
#   endif

For static linking to also work, doesn't that have to be:

#   if defined BOOST_DECL_EXPORTS
#     define BOOST_DECL __declspec(dllexport)
#   elif defined BOOST_DECL_IMPORTS
#     define BOOST_DECL __declspec(dllimport)
#   else
#     define BOOST_DECL
#   endif

And for better error detection, add something like:

#   if defined BOOST_DECL_EXPORTS && defined BOOST_DECL_IMPORTS
#     error both BOOST_DECL_EXPORTS && BOOST_DECL_IMPORTS defined
#   endif
