        * libio/stdio.h (sys_errlist, sys_nerr, _sys_errlist, _sys_nerr):
	Declarations moved to <bits/sys_errlist.h>.  Include that file.
        * libio/Makefile (headers): Add bits/sys_errlist.h to the list.
        * sysdeps/generic/bits/sys_errlist.h: New file.  This does *not*
        declare sys_errlist and sys_nerr.
        * sysdeps/unix/sysv/linux/bits/sys_errlist.h: New file.  Does
	provide declarations.
