Update.
2000-09-09 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/dl-osinfo.h (DL_SYSDEP_OSCHECK): Use uname before trying to read /proc. Patch by Matt Wilson <msw@redhat.com>. * include/sys/utsname.h: Declare __uname. * sysdeps/generic/uname.c: Make uname a weak alias of __uname. * sysdeps/mach/hurd/uname.c: Likewise. * sysdeps/unix/syscalls.list: Likewise. * iconv/gconv_dl.c (do_release_shlib): Rewrite condition for unloading a bit. 2000-09-08 Ulrich Drepper <drepper@redhat.com> * posix/getopt.c (_getopt_internal): When long_only is set always recognize conflicts just like before. 2000-09-08 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * sysdeps/ia64/Makefile (sysdep-rtld-routines): New variable.
