	* sysdeps/posix/sysconf.c (__sysconf) <cases _SC_REALTIME_SIGNALS,
	_SC_PRIORITY_SCHEDULING, _SC_TIMERS, _SC_ASYNCHRONOUS_IO,
	_SC_PRIORITIZED_IO, _SC_SYNCHRONIZED_IO, _SC_FSYNC, _SC_MAPPED_FILES,
	_SC_MEMLOCK, _SC_MEMLOCK_RANGE, _SC_MEMORY_PROTECTION,
	_SC_MESSAGE_PASSING, _SC_SEMAPHORES, _SC_SHARED_MEMORY_OBJECTS,
	_SC_THREADS, _SC_THREAD_SAFE_FUNCTIONS, _SC_THREAD_ATTR_STACKADDR,
	_SC_THREAD_ATTR_STACKSIZE, _SC_THREAD_PRIORITY_SCHEDULING,
	_SC_THREAD_PRIO_INHERIT, _SC_THREAD_PRIO_PROTECT,
	_SC_THREAD_PROCESS_SHARED>: Return _POSIX_* value instead of 1.
	* sysdeps/unix/sysv/linux/sysconf.c (__sysconf)
	<case _SC_MONOTONIC_CLOCK>: Return _POSIX_VERSION instead of 1.

2004-05-07  Jeroen Dekkers  <jeroen@dekkers.cx>

	* sysdeps/mach/hurd/i386/Makefile (CFLAGS-init-first.c): Add
	-momit-leaf-frame-pointer.

	#ifdef AF_PACKET.

	* sysdeps/mach/hurd/getcwd.c
	(_hurd_canonicalize_directory_name_intern): Only realloc when
	size is <= 0.

	* sysdeps/mach/hurd/mmap.c (__mmap): Fail when addr or offset
	isn't page aligned.

	* sysdeps/mach/hurd/spawni.c (EXPAND_DTABLE): Set dtablesize to
	new size.

	* sysdeps/mach/hurd/Versions (GLIBC_PRIVATE): Add __libc_read,

+	* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h (pthread_cond_t):
+	Add __broadcast_seq field.
+	* sysdeps/unix/sysv/linux/sh/pthread_cond_broadcast.S: Mark
+	all waiters as woken with woken_seq and bump broadcast counter.
+	* sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S: Use new
+	__broadcast_seq.  Increment __woken_seq correctly when cleanuped.
+	* sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S: Likewise.
+	Comment typo fixes.  Avoid returning -ETIMEDOUT.
