Changes contributed by Franz Sirl <Franz.Sirl-kernel@lauterbach.com> and Jack Howarth <howarth@bromo.med.uc.edu>. * sysdeps/powerpc/Makefile [$(have-protected) = yes] (CPPFLAGS-divdi3.c, CPPFLAGS-libgcc-compat.S): New variables, pass -DHAVE_DOT_HIDDEN for these files. * sysdeps/powerpc/Versions (libc: GLIBC_2.0): Added __floatdidf, __floatdisf. * sysdeps/powerpc/divdi3.c: New file. * sysdeps/powerpc/libgcc-compat.S: New file, replacement for ... * sysdeps/powerpc/libgcc-compat.c: ... this, file removed.
