* 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.
