* sysdeps/powerpc/dl-machine.c: Include dl-machine.h after the other header files...

* sysdeps/powerpc/fpu/s_rint.c: Handle rounding to -0 correctly.
* sysdeps/powerpc/fpu/s_rintf.c: Likewise.

* sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add getrlimit
and setrlimit syscalls for backwards compatibility.
2000-04-11  Geoff Keating  <geoffk@cygnus.com>

	* sysdeps/powerpc/dl-machine.c: Include dl-machine.h after the
	other header files.  Mention about 128-byte cache line sizes.
	(__elf_machine_fixup_plt): Make types match elf_machine_fixup_plt.
	* sysdeps/powerpc/dl-machine.h (elf_machine_fixup_plt): Update
	for current calling sequence.
	* sysdeps/powerpc/dl-start.S (_dl_start_user): Close comment.

	* sysdeps/powerpc/fpu/s_rint.c: Handle rounding to -0 correctly.
	* sysdeps/powerpc/fpu/s_rintf.c: Likewise.

	* sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add getrlimit
