    # from templates) should be exposed in shared libraries as weak symbols but
    # this is only needed when we expose those types in the shared library API
    # in any way. We don't use C++ std types in the API and we also don't
    # support exceptions in the library.
    # See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36022 for a discussion
    # about this.
