# These are the functions which clang needs when it is targetting a previous
# version of the OS. The issue is that the backend may use functions which were
# not present in the libgcc that shipped on the platform. In such cases, we link
# with a version of the library which contains private_extern definitions of all
# the extra functions which might be referenced.
