+       close: No longer depend on module 'fclose'.
+       * modules/close (Depends-on): Remove fclose.
+       * NEWS: Mention the change.
+       Suggested by Sam Steingold <sds@gnu.org>.

+
+       fsusage: Enable large volume support on AIX >= 5.2.
+       * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): If 'struct statvfs64' has a
+       larger f_blocks field than 'struct statvfs', define STAT_STATVFS64
+       instead of STAT_STATVFS.
+       * lib/fsusage.c (get_fs_usage) [STAT_STATVFS64]: Use statvfs64.
+
+       fsusage: Restore previous behaviour on AIX, Cygwin, Interix.
+       * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Enforce a 64-bit struct statvfs
+       f_blocks field only on MacOS X.
+
+       fsusage: Support large volumes on glibc/Hurd, HP-UX, Solaris, MacOS X.
+       * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Require AC_SYS_LARGEFILE.
+       * modules/fsusage (Depends-on): Add largefile.

+       ftell: don't include <unistd.h>
+       * lib/ftell.c: Don't include <unistd.h>.  <stdio.h> is now
+       guaranteed to define off_t, and the ftell module depends on the
+       stdio module.
+
+       ftell: do not assume wraparound signed arithmetic
+       * lib/ftell.c: Include <limits.h>.
+       (ftell): Don't assume wraparound signed arithmetic.
+
        * README: Modernize discussion of signed integers.
        Assuming overflow wraparound is no longer safe.
        Mention ones' complement and signed magnitude.
