	* sysdeps/unix/sysv/linux/net/if_ppp.h (PPP_VERSION): Define to
	2.2.0 to prevent version mismatch.

1997-03-17 19:26  Andreas Jaeger  <aj@arthur.pfalz.de>

	(elf_machine_runtime_setup): Simplify and correct expressions.
	(RTLD_START): Fix bug changing _dl_starting_up.
	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Added. Deal with

	anyone ever used them. Use memcpy for copy reloc, it'll be safe.
	Never target branch relocations at a PLT entry.

	* sysdeps/powerpc/bsd-setjmp.S: Make jump to PLT entry if we are
	generating PIC.
