Move warnings about sys_errlist[], sys_nerr, __sys_errlist, _sys_nerr to _sys_siglist.c, so the warning is shown once at link time, not three times (once for errlist.c itself, once each for the two includes in _sys_siglist.c). 1998-12-06 10:12:18 +03:00			`/* $NetBSD: _sys_errlist.c,v 1.7 1998/12/06 07:12:18 jonathan Exp $ */`

Changed name of __weak_reference() to __indr_reference(). They really are indirect references, and I want to add a real __weak_reference() macro to <machine/cdefs.h> soon. 1995-03-23 22:58:48 +03:00			`#ifdef __indr_reference`
