Update.
2003-08-07 Jakub Jelinek <jakub@redhat.com> * sysdeps/generic/ldsodefs.h (_rtld_global): Add _dl_rtld_lock_recursive and _dl_rtld_unlock_recursive. * elf/rtld.c (rtld_lock_default_lock_recursive, rtld_lock_default_unlock_recursive): New functions. (dl_main): Initialize _dl_rtld_lock_recursive and _dl_rtld_unlock_recursive. 2003-08-05 Jakub Jelinek <jakub@redhat.com> * elf/ldconfig.c (main): Append SLIBDIR and LIBDIR to config_file directories instead of prepending.
