It was reported that API symbols were being "exported" from the static library built with MSVC, causing them to remain exported after being linked into another program. It turns out this was actually a problem outside of MSVC as well. The solution is to always build the static and shared libraries from different object files, where the API symbols are exported from the shared library object files but not from the static library object files.
