Update.

1999-08-18  Ulrich Drepper  <drepper@cygnus.com>

	* Rules: When generating stdio_lim.h also rewrite IOV_MAX definition.
	* stdio-common/stdio_lim.h.in: Add IOV_MAX template.
	* include/bits/xopen_lim.h: Don't define IOV_MAX here, get it from
	stdio_lim.h.  Define LONG_BIT and WORD_BIT.

	* include/features.h: Define __USE_XOPEN2K if _XOPEN_SOURCE == 600.

	* libio/stdio.h: Don't declare cuserid and getopt for X/Open issue 6.

	* misc/search.h: Don't define NULL.

	* posix/sys/types.h: Define blksize_t if it hasn't happened.
	Only define key_t and blkcnt_t if it hasn't happened before.
	Define blksize_t if not happened before.
	* io/sys/stat.h: Don't define pid_t.  Define blkcnt_t and blksize_t.
	* sysdeps/generic/bits/types.h: Define __blksize_t.
	* sysdeps/unix/sysv/linux/alpha/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/types.h: Likewise.
	* sysdeps/unix/sysv/sysv4/solaris2/bits/types.h: Likewise.
	* sysdeps/mach/hurd/bits/stat.h (struct stat): Use __blksize_t for
	st_blksize member.
	(struct stat64): Likewise.
	* sysdeps/unix/bsd/bits/stat.h: Likewise.
	* sysdeps/unix/bsd/osf/alpha/bits/stat.h: Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/stat.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/stat.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/stat.h: Likewise.
	* sysdeps/unix/sysv/sysv4/i386/bist/stat.h: Likewise.
	* sysdeps/unix/sysv/sysv4/solaris2/bits/stat.h: Likewise.

	* stdlib/getsubopt.c: Correct type of second argument.
	* stdlib/stdlib.h: Likewise.

	* stdlib/monetary.h: Don't include sys/types.h.  Define only size_t
	and ssize_t.

	* sysdeps/generic/putenv.c: Correct type of parameter.
	* stdlib/stdlib.h: Likewise.

	* sysdeps/generic/msgsnd.c: Correct type of second parameter.
	* sysdeps/unix/sysv/linux/msgsnd.c: Likewise.
	* sysvips/sys/msg.h: Likewise.

	* sysdeps/generic/semop.c: Correct type of third parameter.
	* sysdeps/unix/sysv/linux/semop.c: Likewise.
	* sysvipc/sys/sem.h: Likewise.  Don't include sys/types.h, define
	size_t.

	* sysdeps/generic/shmget.c: Correct type of second parameter.
	* sysdeps/unix/sysv/linux/shmget.c: Likewise.
	* sysvips/sys/shm.h: Likewise.  Don't include unistd.h and sys/types.h.
	Declare __getpagesize here.

	* sysdeps/generic/bits/ipc.h: Include bits/types.h instead of
	sys/types.h.
	* sysdeps/gnu/bits/ipc.h: Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/ipc.h: Likewise.

	* sysvipc/sys/ipc.h: Define uid_t, gid_t, mode_t, and key_t if not
	already done.

	* sysdeps/unix/bsd/usleep.c: Correct type of parameter.

	* debug/versions: Export __cyg_profile_func_enter and
	__cyg_profile_func_exit.

	* math/bits/mathcalls.h: Pretty print.
