* sysdeps/pthread/bits/libc-tsd.h: Include <tls.h>.
	[USE_TLS && HAVE___THREAD]: Just include the sysdeps/generic file,
	which does the right thing when __thread support is available.
	* descr.h (struct _pthread_descr_struct) [USE_TLS && HAVE___THREAD]:
	Omit `p_libc_specific', `p_errnop', `p_errno', `p_h_errnop',
	`p_h_errno', `p_resp', and `p_res' members.
	* pthread.c (__pthread_initialize_minimal) [USE_TLS && HAVE___THREAD]:
	Don't initialize `p_errnop' and `p_h_errnop' members.
	(__pthread_reset_main_thread): Likewise.
	(__pthread_initialize_manager): Likewise.
	* manager.c (__pthread_manager, pthread_handle_create): Likewise.
	* pthread.c (pthread_initialize) [USE_TLS && HAVE___THREAD]:
	Don't initialize `p_resp' member.
	(__pthread_reset_main_thread): Likewise.
	* manager.c (pthread_handle_create): Likewise.
	* specific.c (libc_internal_tsd_set, libc_internal_tsd_get):
	Conditionalize these on [!(USE_TLS && HAVE___THREAD)].
	* errno.c [USE_TLS && HAVE___THREAD]
	(__h_errno_location, __res_state): Don't define these at all.

	* sysdeps/i386/tls.h (INSTALL_DTV): Add parens around arguments!
	(INSTALL_NEW_DTV, GET_DTV): Likewise.
	* sysdeps/sh/tls.h (INSTALL_DTV, INSTALL_NEW_DTV, GET_DTV): Likewise.

	* weaks.c: Don't include <errno.h> here.

2002-08-01  Roland McGrath  <roland@redhat.com>

	* sysdeps/i386/tls.h (TLS_DO_MODIFY_LDT): New macro, broken out of
	TLS_INIT_TP.
	(TLS_DO_SET_THREAD_AREA): New macro, uses thread_set_area syscall.
	(TLS_SETUP_GS_SEGMENT): New macro, try one or the other or both.
	(TLS_INIT_TP): Use that.
