Here's a notable distinction between GCC's visibility attribute and MSVC's __declspec: The latter is accepted on forward declarations while the latter produces a warning[*] and is otherwise ignored.

Yes, this is a known issue. My patch removes the macros from some declarations. msvc seems to work without them anyway. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !
