Update.
2003-06-24  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/fstatfs64.c (__fstatfs64): Add support
	for the fstatfs64 syscall.
	* sysdeps/unix/sysv/linux/statfs64.c (__statfs64): Add support for
	the statfs64 syscall.

	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_STATFS64 appropriately.

	* sysdeps/unix/sysv/linux/internal_statvfs.c: Use f_frsize field
	from statfs structure if it has been filled in.

	* sysdeps/unix/sysv/linux/bits/statfs.h (struct statfs): Add f_frsize
	field.
	(struct statfs64): Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/statfs.h: Likewise.
	* sysdeps/unix/sysv/linux/s390/bits/statfs.h: Likewise.

	instead of __libc_cleanup_region_*.
