Update.
2003-04-22 Jakub Jelinek <jakub@redhat.com> * include/link.h (NO_TLS_OFFSET): Define to 0 if not defined. * elf/dl-close.c (_dl_close): Use NO_TLS_OFFSET. * elf/dl-object.c (_dl_new_object): Initialize l_tls_offset to NO_TLS_OFFSET. * elf/rtld.c (_dl_start_final, _dl_start): Likewise. * elf/dl-reloc.c (CHECK_STATIC_TLS): Use NO_TLS_OFFSET. * sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Likewise. * sysdeps/powerpc/dl-tls.h (TLS_TPREL_VALUE): Don't subtract TLS_TCB_SIZE.
