I don't think there's a Windows equivalent for that. If you use such a flag, 
your code is inherently not portable to Windows.

I could be wrong though. I think gcc-on-windows supports an "export everything 
defined/import everything not defined" feature, but I don't know if it helps 
or if there's an equivalent for MSVC. In special, since your headers won't 
have the proper markers, you may need to force all applications linking to 
your library to use the same feature.
