Browse Source 
* sysdeps/unix/sysv/linux/poll.c: Don't define as stub.  Use
	simulation of system call using select.

	* sysdeps/unix/sysv/linux/signal.c: Use POSIX implementation.

	* sysdeps/unix/sysv/linux/statbuf.h: Define _STAT_VER.

	* sysdeps/unix/sysv/linux/i386/sigaction.c: Correct parameter
	name usage (new->act, old->oact).
	Correct asm statement because of gcc strangeness.
	
	* sysdeps/i386/i586/strchr.S: Correct typos: cmp -> cmpb.

	* sunrpc/clnt_perr.c: Remove declaration of sys_errlist.  They
	conflict with the ones in stdio.h.

	* string/tester.c: %Z is no complete format.  Change to %Zd.

	* sysdeps/mach/hurd/symlink.c (__symlink): Ditto.
