The GCC manual says that __declspec((dllimport)) and 
__declspec((dllexport)) are equivalent to __attribute__((dllimport)) and 
__attribute__((dllimport)), so I assume they can be used as other 
attributes but I don't know for sure what MSVC allows.  Maybe it is 
documented somewhere?  I can only test with MinGW.
