As Mike noted earlier on in this thread, the troublemaker symbols are
forced to default visibility in the standard headers. Hence,
-fvisibility doesn't gain us much here. I conclude from this thread that
using symbols files for C++ ABIs is pretty much a bad idea at the
moment.
Thanks for the input!
