what are the coding/runtime mechanisms for IEEE 754-2008 decimal floating point
recall that ast does its own string<=>fp conversions
these work for IEEE 754
but no provisions have been made for IEEE 754-2008
(it may be that no provisions are necessary)
in particular, can a single process switch between IEEE 754 and IEEE 754-2008?

src/cmd/ksh93/sh/init.c must include FEATURE/externs and didn't
this has been fixed
