My patch does exactly the same Zack did for IA-64.  x86-64 has exactly
symetric behaviour wrt long double and __float128 as IA-64 ABI has.  I
really hope that if Zack works out the issues with Ada, it will
automatically fix the x86-64 part too.  I can do any help with fixing
the bug if Zack figure out how to make me involved in his effort.
