// The build system builds the rust library ipcclientcerts as a static library
// called ipcclientcerts_static. On macOS and Windows, that static library can
// be linked with an empty file and turned into a shared library with the
// function C_GetFunctionList exposed. This allows that shared library to be
// used as a PKCS#11 module (see osclientcerts).
// Unfortunately, on Linux, exposing the C_GetFunctionList in the static
// library doesn't work for some unknown reason. As a workaround, this file
// declares its own C_GetFunctionList that can be exposed in the shared
// library. It then calls the function IPCCC_GetFunctionList exposed
// (internally to the linkage in question) by ipcclientcerts. This enables
// the build system to ultimately turn ipcclientcerts into a shared library
// that exposes a C_GetFunctionList function, meaning it can be used as a
// PKCS#11 module.

// On MinGW there's a toolchain mismatch that results in _Unwind_Resume being
