PS: On x86-32 I see that 64 bit arithmetic is being used.  Consulting
the gcc tree dumps it seems that this is because it is doing arithmetic
using "bitsizetype", a gcc internal type, which has twice as many bits
as the system word size (so 128 bits on your machine).  I checked that
mainline gcc-4.2 is also using bitsizetype for your testcase.  So while
I understand your surprise at this testcase doing 128 bit arithmetic,
this is really a gcc issue: mainline generates 128 bit arithmetic for it
too, only you never noticed :)  I'm closing this as invalid.  However it
could also be marked a duplicate of the bug asking for 128 bit support
(PR1462) if you like.
