    First, have you tried to search archives? Recommended. It's only
about week when I dumped my achievements in making dlls sane.

    Resuming: __declspec(dllexport) is strictly optional;
__declspec(dllimport) is in some way "mandatory", however, I worked
out technique how to subdue even it. http://www.is.lg.ua/~paul/devel/
may contain background information and examples you want.

    Your logic is strange. If I'd dislike "M$ weirdness" as you do,
I'd use only GNU tools, what exactly I do. So, consider giving up
msvc.
