Update.
2002-05-20  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

	* sysdeps/powerpc/Makefile (sysdeps_routines): Use libgcc-compat
	instead of cmpdi2, shdi3, fixdfdi, fixsfdi in csu dir.
	(shared-only-routines): Likewise.
	* sysdeps/powerpc/libgcc-compat.c: New file.
	* sysdeps/wordsize-32/cmpdi2.c: Removed.
	* sysdeps/wordsize-32/fixdfdi.c: Removed.
	* sysdeps/wordsize-32/fixsfdi.c: Removed.
	* sysdeps/wordsize-32/shdi3.c: Removed.
