Update.
2003-05-31  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_plt_conflict):
	New function.
	(elf_machine_rela) <case R_PPC64_JMP_SLOT>: Avoid
	RESOLVE_CONFLICT_FIND_MAP.  If RESOLVE_CONFLICT_FIND_MAP is defined,
	call elf_machine_plt_conflict instead of elf_machine_fixup_plt.

	* sysdeps/i386/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE): Add
	CFI directives.

	* csu/Makefile: Fix Makefile warnings regarding Scrt1.o.
