  fsusage: fix block size returned on older Linux 2.6
  
  * lib/fsusage.c: Fall back to (struct statfs).f_frsize
  which is available since Linux 2.6.
  * m4/fsusage.m4 (STAT_STATFS2_FRSIZE): Always define
  when the member is available so it can be used as a fallback.
  * doc/posix-functions/statvfs.texi: Mention the hang issue
  on Linux < 2.6.36.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  MacOS X 10.3, OpenBSD 3.8, mingw, MSVC 9.
  @item
  This function can hang if it stats all preceding
  entries in /proc/mounts, and any of those file systems
  are hard-mounted and not available.  This affects
  Linux < 2.6.36.
  @item
  On platforms where @code{f_blocks} in @samp{struct statvfs} is a 32-bit
  value, this function may not work correctly on files systems larger than
  4 TiB.  The fix is to use the @code{AC_SYS_LARGEFILE} macro.  This affects
  glibc/Hurd, HP-UX 11, Solaris.
  @end itemize
  
  Gnulib provides a module @code{fsusage} that provides similar information
  as @code{statvfs}.
