Eventually the day will come when one want something bigger, then,
you have to break abi for this. We did this on darwin, and ick,

double, as the upgrade path is clear.
2) Choose a sensible format for long double. The obvious candidate
is a
128-bit PPC/MIPS stye almost-quad precision type implemented with a
pair of
64-bit doubles.
Yup, makes sense, though I do worry when CPU designers give up a real
128 long double in hardware that then doesn't match the software,
but, maybe they'll never do that...
