right, so William could declare only "setup" with __attribute__((visibility("default"))) and in your makefile:

ifeq ($(make-lib-executable),yes)
  ldflags := -fvisibility=hidden

Note that this doesn't work on Windows because MinGW ignores visibility attributes. But there's a solution:

On MinGW, GCC exports all non-static symbols unless at least one symbol is declared with __declspec(dllexport).

For Windows, simply declare the library's "setup" function with __declspec(dllexport).
"make-lib-executable=yes" -> only the "setup" function is exported.
"make-lib-executable=no" -> the file containing the "setup" function won't be compiled, so all other non-static symbols are exported (as usual).
