Update.
2002-02-07 Ulrich Drepper <drepper@redhat.com> * sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Account for alignment of the TCB and store total size and alignment of static TLS block in _dl_tls_static_size and _dl_tls_static_align. tls_index is a typedef. * sysdeps/generic/ldsodefs.h: Declare _dl_tls_static_size and _dl_tls_static_align. * sysdeps/i386/dl-tls.h: tls_index is a typedef. * elf/dl-support.c: Define _dl_tls_static_size and _dl_tls_static_align.
