	* sysdeps/unix/sysv/linux/i386/Makefile: New file.

Wed Apr 24 17:35:30  Ulrich Drepper  <drepper@cygnus.com>

	* inet/netinet/in.h, socket/sys/socket.h: Move to
	sysdeps/generic/netinet/in.h, sysdeps/generic/sys/socket.h.
	* netinet/in.h, sys/socket.h: Remove file.

	* misc/Makefile (routines): Add fdatasync.

	* posix/Makefile (headers): Add sched.h.
	(routines): Add nanosleep, sched_setp, sched_getp, sched_sets,
	sched_gets, sched_yield, sched_primax, sched_primin, sched_rr_gi.

	* posix/getconf.c (vars): Add entries for _POSIX_REALTIME_SIGNALS,
	_POSIX_PRIORITY_SCHEDULING, _POSIX_TIMERS, _POSIX_ASYNCHRONOUS_IO,
	_POSIX_PRIORITIZED_IO, _POSIX_SYNCHRONIZED_IO, _POSIX_FSYNC,
	_POSIX_MAPPED_FILES, _POSIX_MEMLOCK, _POSIX_MEMLOCK_RANGE,
	_POSIX_MEMORY_PROTECTION, _POSIX_MESSAGE_PASSING,
	_POSIX_SEMAPHORES, _POSIX_SHARED_MEMORY_OBJECTS.

	* posix/sched.h: New file.  Header for POSIX scheduling interface.

	* posix/unistd.h: Describe options from POSIX.4.
	Add declaration of fdatasync.

	* sysdeps/generic/confname.h: Add definition for
	 _SC_REALTIME_SIGNALS, _SC_PRIORITY_SCHEDULING, _SC_TIMERS,

	_SC_SEMAPHORES, _SC_SHARED_MEMORY_OBJECTS.

	* sysdeps/generic/fdatasync.c: New file.  Default implementation
	simply uses fsync.

	* sysdeps/generic/netinit/in.h: Moved to here from inet/netinet/in.h.

	* sysdeps/generic/schedbits.h: New file.  System dependent
	defintion for POSIX.4 scheduling interface.

	sysdeps/stub/sched_setp.c, sysdeps/stub/sched_sets.c,
	sysdeps/stub/sched_yield.c: New file:  Stub implementation
	for systems missing these POSIX.4 system calls.

	* sysdeps/unix/sysv/linux/gnu/types.h,
	sysdeps/unix/sysv/linux/ioctls.h: Use kernel header for
	data type definitions.

	* sysdeps/unix/sysv/linux/netinet/in.h: New file.  Linux
	specific version.

	* sysdeps/unix/sysv/linux/posix_opt.h: New file.  Define POSIX
	options applicable for Linux.

	* sysdeps/unix/sysv/linux/syscalls.list: Add definitions for
	fdatasync, nanosleep, sched_setparam, sched_getparam,
	sched_setscheduler, sched_getscheduler, sched_yield,
	sched_get_priority_max, sched_get_priority_min, and
	sched_rr_get_interval.

	* sysdeps/unix/sysv/linux/sysconf.c: Add handling of POSIX.4
	options.

	* sysdeps/unix/sysv/linux/termbits.h: Use kernel headers.

	* time/sys/time.h: Remove definition of `struct timespec'.

	* time/time.h (struct timespec): Move definition to here.
