Awesome, thanks! I recall that we talked about this last year, and
the blocking issue was that gcc didn't support it. It appears
that the one in the base system still doesn't, but now that clang
is the default compiler, maybe that doesn't matter.

There are some regression tests in tools/regression/lib/msun that
could be converted to exercise these macros if you wish: grep for
"cpack".
