As Paolo responded, we have already begun - I use autoconf to detect both visibility support and decimal float support. I'm not sure how much else remains to be done, but I'm open to suggestions :-) I wonder if it's possible to work out some of the difuncs/tifuncs stuff based on the size of target types. -- Daniel Jacobowitz CodeSourcery
