Update.

2003-09-16  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/Dist: Remove internal_statvfs.c.
	* sysdeps/unix/sysv/linux/Makefile [subdir=io] (sysdep_routines):
	Add internal_statvfs.
	* sysdeps/unix/sysv/linux/fstatvfs.c: Call __internal_statvfs
	instead of including "internal_statvfs.c".
	* sysdeps/unix/sysv/linux/statvfs.c: Likewise.
	* sysdeps/unix/sysv/linux/internal_statvfs.c: Make it a real function.
	Add code to avoid the stat calls on all the reported mount points
	when we can determine mismatch in advance.
	* sysdeps/unix/sysv/linux/linux_fsinfo.h: Add AUTOFS_SUPER_MAGIC and
	USBDEVFS_SUPER_MAGIC.

2003-09-16  Jakub Jelinek  <jakub@redhat.com>

	* posix/Versions (sched_getaffinity, sched_setaffinity): Change
	from GLIBC_2.3.2 to GLIBC_2.3.3 symbol version.

2003-09-16  Bruno Haible  <bruno@clisp.org>

	* intl/tst-gettext2.sh: Set GCONV_PATH and LOCPATH only after
	invoking msgfmt, not before.
