Update.
2002-08-28 Jakub Jelinek <jakub@redhat.com> * sysdeps/ia64/elf/configure.in (PI_STATIC_AND_HIDDEN): Define unconditionally. * sysdeps/alpha/elf/configure.in (libc_cv_alpha_hidden_gprel): New check. (PI_STATIC_AND_HIDDEN): Define if check succeeded. 2002-08-28 Jakub Jelinek <jakub@redhat.com> * locale/loadarchive.c (_nl_load_locale_from_archive): Add fd >= 0 check to close_and_out close. Replace return NULL statements where fd might be >= 0 with goto close_and_out. Close the file descriptor when it is no longer needed.
