Update.
2002-02-23 Ulrich Drepper <drepper@redhat.com> * csu/set-init.c: Moved to... * sysdeps/mach/hurd/set-init.c: ...here. New file. * csu/Makefile: Don't compile set-init. * sysdeps/mach/hurd/Makefile: Compile set-init for subdir csu. * sysdeps/mach/hurd/i386/init-first.c: Call __init_misc in addition to __libc_init. * sysdeps/mach/hurd/mips/init-first.c: Likewise. * sysdeps/mach/hurd/powerpc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/init-first.c: Call __init_misc instead of __libc_init. * misc/init-misc.c: Always export __init_misc. Don't define hooks for __libc_subinit.
