You should also arrange for the proper symbol versions to be used for
these functions to reflect the version in which they are added. Don't
make the mistake made for x86_64 GNU/Linux of getting some of the
versions wrong.
%ifdef __x86_64__
# Those symbols had improper versions when they were added to gcc 4.3.0.
# We corrected the default version to GCC_4.3.0. But we keep the old
# version for backward binary compatibility.
