Unfortunately most of Mark's comments are still unaddressed. The
formatting doesn't follow the GNU coding standards, and the real
issue with this patch is that there are a lot of systems out in the
world that use 64-bit long double still.
I mentioned last week on gdb@ and binutils@ that I think we need a way
to mark the ABI used by PowerPC binaries. That would easily cover
this also. I'll be thinking about it more next week.
