+On platforms where @code{off_t} is a 32-bit type, @code{fstatat} may
+not correctly report the size of files or block devices larger than 2
+GB. The fix is to use the @code{AC_SYS_LARGEFILE} macro.

+On Windows platforms (excluding Cygwin), @code{st_ino} is always 0.

+On some file systems, @code{st_size} contains bogus information for
+symlinks; use the gnulib module areadlink-with-size for a better way
+to get symlink contents.
