Update.
2002-08-25 Ulrich Drepper <drepper@redhat.com>
* sysdeps/i386/elf/configure.in: Unconditionally define
PI_STATIC_AND_HIDDEN.
* elf/rtld.c (DONT_USE_BOOTSTRAP_MAP): Define only if
PI_STATIC_AND_HIDDEN is defined as well.
* config.h.in: Add PI_STATIC_AND_HIDDEN entry.
* elf/rtld.c (dl_main): Likewise.
