             Bug #: 11867
           Summary: __SIZEOF_LONG_DOUBLE__ and __SIZE_TYPE__ are incorrect
                    on Linux/ppc
           Product: clang
           Version: trunk
          Platform: All

I mentioned this in #11028, but that ticket focused more on the __linux__
issue, so this is a separate followup.
