Export shared libraries in cross-platform form?

Question

Is there a cross-platform way to selectively export certain functions and structures from a C project that creates a shared library?

I want to make sure that a specific build system is not required (visibility must be defined in the code, for example, as a macro), and in a way that both GCC and MSVC can understand.

Thanks.

Strictly not, of course, because toolchains do not match.
