Update.

2000-08-12  Andreas Jaeger  <aj@suse.de>

	* include/features.h (__STDC_ISO_10646__): Define.
	Reported by Markus Kuhn <Markus.Kuhn@cl.cam.ac.uk>.

	* include/features.h (__USE_ISOC99): Define for _XOPEN_SOURCE >= 600.

	* locale/langinfo.h: Define YESSTR and NOSTR also for XPG4 (but not
	for revision 6 and up).

	* posix/sys/types.h: Define __need_timer_t and __need_clockid_t before
	including <time.h>.
	* time/time.h: Allow __need_timer_t and __need_clockid_t to be defined
	to get definitions of just these types.

	* signal/signal.h: Define thread signal handling functions also for
	POSIX95.

	* sysdeps/unix/sysv/linux/bits/types.h: Define thread types also for
	POSIX95.
	* sysdeps/unix/sysv/linux/alpha/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/ia64/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/types.h: Likewise.

	* sysvipc/sys/shm.h: Define pid_t for XPG.

	* wcsmbs/wchar.h: Make the various wide char string and stream
	functions available for the respective XPG versions.
