I can confirm this on the mainline (20030806) but I think the problem is that powerpc-darwin does 
not support 128bit long double's, I think the fix is to add TARGET_MACHO to the support where 
TARGET_AIX is, but I do not know this for sure.

Confirmed mainline (20031115). Geoff's recent patch <http://gcc.gnu.org/ml/gcc-patches/2003-
11/msg01113.html> did not fix this.

Note that even when this is fixed, -mlong-double-128 (and especially this testcase) won't work on 
Darwin because the library support for it is not there.  That's not a GCC problem.
