Update.
2002-08-20 Ulrich Drepper <drepper@redhat.com> * elf/rtld.c (_dl_start): Pass zero to TLS_INIT_TP. Set bootstrap_map.l_tls_tp_initialized to 1 if TLS_INIT_TP was called. (_dl_start_final): Copy l_tls_tp_initialized to GL(dl_rtld_map). (dl_main): If HAVE___THREAD is not defined pass l_tls_tp_initialized to TL_INIT_TP. Otherwise pass 1. * include/link.h (struct link_map): Add l_tls_tp_initialized. * sysdeps/generic/libc-tls.c (__libc_setup_tls): Pass 0 to TL_INIT_TP. 2002-08-20 Brian Youmans <3diff@gnu.org> * manual/contrib.texi: Removed licenses, added acknowledgements for contributions by Intel, IBM, Craig Metz. * LICENSES: New file, contains the text of all non-FSF licenses in the * sysdeps/mach/hurd/net/if_ppp.h: Replaced CMU license with a new one modelled on the modern BSD license, per recent letter of permission from CMU. * sysdeps/unix/sysv/linux/net/if_ppp.h: Likewise. * sysdeps/ieee754/dbl-64/MathLib.h: Changed the copyright holder from IBM to FSF, per the recent Software Letter.
