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.
