RTH is listed as the author of a lot of those bits, so perhaps he knows more?

The glibc bits handle ieee quad format, whereas I don't believe that Torbajorn's does. I don't recall if Torbajorn's code allows for emulation of all rounding modes or exception bits.

But I suspect that Torbajorn's code compiles down smaller, which is likely to be helpful to the folk that actually need it.

The GLIBC bits claim to be LGPL'd, so that would indeed need a change to include them in libgcc.

I wouldn't expect that to be a problem.
