In addition, as I mentioned at the GCC Summit, could someone revert
2006-01-27 Roland McGrath <roland@redhat.com>
* sysdeps/powerpc/nofpu/Makefile [$(subdir) = soft-fp]
(sysdep_routines): Add $(gcc-quad-routines) here.
and remove the *tf* functions from sysdeps/powerpc/nofpu/Versions? The
*tf* functions, for IEEE quad long double, should not be used on PowerPC,
and since they haven't appeared in a release with functional --without-fp
PowerPC support, it is still safe to remove them from libc.
