* sysdeps/unix/sysv/linux/sys/ptrace.h [PTRACE_SETOPTIONS,

	PTRACE_GETEVENTMSG, PTRACE_GETSIGINFO, PTRACE_SETSIGINFO]: Define.
	* sysdeps/unix/sysv/linux/ptrace.c [PTRACE_SETOPTIONS,
	PTRACE_GETEVENTMSG, PTRACE_GETSIGINFO, PTRACE_SETSIGINFO]: Check.

2006-09-16  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc32/register-dump.h (register_dump): Don't
	write '\0' to the fd.
	* sysdeps/mach/hurd/powerpc/register-dump.h (register_dump): Likewise.
	* sysdeps/powerpc/powerpc64/register-dump.h (register_dump): Likewise.
	Change regs to unsigned long pointer from unsigned int, fix fscr
	offset.
