	* 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>

	* stdio-common/printf_fphex.c (MIN): Only define MIN if not
	already defined.

	* sysdeps/powerpc/elf/start.c (__start1): Fix bug for static objects.
	* sysdeps/powerpc/dl-machine.h (elf_machine_rela): Fix bugs in
	jump slot relocation. Prefer relative branches (some PowerPC chips
	don't predict absolute branches).
	(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
	strange Linux/PPC padding of initial stack.

	* sysdeps/unix/sysv/linux/powerpc/termbits.h: Increase NCCS to 39,

	static.

	* sysdeps/powerpc/elf/start.c (_start): Use .previous to avoid
	confusing gcc's idea of the current section.

	* sysdeps/powerpc/dl-machine.h (elf_machine_rela,
	elf_machine_runtime_setup): Flush data & instruction caches when
	necessary, for 603/604 support. Add better support for large PLTs.
	(elf_machine_rela): Remove relocations that wouldn't work if
	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.
	* sysdeps/powerpc/bsd-_setjmp.S: Likewise.
