This function is missing on some platforms:
-AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 11 2010-11, mingw, BeOS.

+On platforms where @code{off_t} is a 32-bit type, this function may not
+correctly report the size of files or block devices larger than 2 GB and
+may not work correctly on huge directories larger than 2 GB. Also, on
+platforms where @code{ino_t} is a 32-bit type, this function may report
+inode numbers incorrectly. The fix is to use the @code{AC_SYS_LARGEFILE}
+macro (only on MacOS X systems).
