--- Comment #6 from Pedro Alves <palves at redhat dot com> ---
I'm having mixed feelings about LONGEST->__int128  :-(  A lot of code uses
(U)LONGEST for indexes, sizes and also to hold register values.  Most of these
places won't ever need the extended precision.  I'm not sure whether forcing
everything to use 128-bit is a good idea, both efficiency/ABI -wise, and
memory-space wise.  :-/
