--- Comment #5 from Michael Meissner <meissner at gcc dot gnu.org> --- Note, at the moment, the patches are to make the existing configure switch (--with-long-double=ieee) work correctly. However, we need all of the pieces in place (gcc, glibc, libstdc++, etc.) before we can contemplate changing the ABI.
