I would have thought sys_nerr should not be defined at all, just as
sys_errlist is not. The two go together. In fact, before your report I
thought it was not defined. In the libc change logs (libc/ChangeLog.8) I
see:
1998-06-01 Gordon Matzigkeit <[EMAIL PROTECTED]>
* sysdeps/mach/hurd/errlist.c (sys_nerr, _sys_nerr): Make weak
aliases for _hurd_nerr, for programs that don't use sys_errlist,
but need sys_err.
We haven't heard from Gord in a long time, so we'll have to guess or
research what motivated this. It doesn't really make sense to me.
