From a808d541c6fb36db381923c52040855602e9fd83 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 28 Feb 2000 21:16:38 +0000 Subject: Update. 2000-02-28 Ulrich Drepper * sysdeps/unix/start.c: Initialize __errno and add comment explaining why. Remove K&R compatibility. * sysdeps/powerpc/fpu/s_isnan.c: Avoid using asm statement to declare aliases. * sysdeps/powerpc/Makefile: Always pass flags to compile for ppc and not rs6000. [$(subdir)=misc] (sysdep_routines): Add gprsave0, gprrest0, gprsave1 , and gprrest1. Don't pass special flags to compiler for init and gmon-start if this is no ELF platform. * sysdeps/mach/hurd/bits/statfs.h: Define _STATFS_F_NAMELEN. * sysdeps/unix/sysv/linux/bits/statfs.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/statfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/statfs.h: Likewise. * sysdeps/posix/fpathconf.c: Don't unconditionally use f_namelen in statfs. Check feature macro and use f_name_max or NAME_MAX instead. * sysdeps/posix/pathconf.c: Likewise. * dlfcn/dlfcn.h: Remove DL_CALL_FCT definition here. * sysdeps/generic/bits/dlfcn.h: Define DL_CALL_FCT here. * sysdeps/mips/bits/dlfcn.h: Define DL_CALL_FCT here. * iconv/skeleton.c: If DL_CALL_FCT is not yet defined, add dumy definition here. * sysdeps/generic/libc-start.c: Fix typo in comment. * include/set-hooks.h: Allow systems to not define symbol_set_define. * configure.in: Unify machine names rs6000 and powerpc. --- include/set-hooks.h | 33 +++++++++++++++++++++++---------- 1 file changed, 23 insertions(+), 10 deletions(-) (limited to 'include/set-hooks.h') diff --git a/include/set-hooks.h b/include/set-hooks.h index 995bdf4120..1666485e50 100644 --- a/include/set-hooks.h +++ b/include/set-hooks.h @@ -1,5 +1,5 @@ /* Macros for using symbol sets for running lists of functions. - Copyright (C) 1994, 1995, 1997 Free Software Foundation, Inc. + Copyright (C) 1994, 1995, 1997, 2000 Free Software Foundation, Inc.
