Nice, if you are not working on my platform.  In my initial message,

 From dmesg:
CPU: Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz (4160.12-MHz K8-class CPU)
   Origin = "GenuineIntel"  Id = 0x206d6  Family = 6  Model = 2d 
Stepping = 6

And, I also said the __float128 is likely to leave me with some code 
that is orphaned.
