How to compile the git mirror of coreutils?

[Hongxu Chen]

Hi guys,

  This question might be a bit silly, but I just cannot build the
  latest development version of coreutils, which I cloned from

      git://git.sv.gnu.org/coreutils.git

  When I use `autoreconf -fiv`, it complains:

  autoreconf: Entering directory `.'
  autoreconf: running: autopoint --force
  autoreconf: running: aclocal --force -I m4
  aclocal: configure.ac:429: file `m4/cu-progs.m4' does not exist
  autoreconf: aclocal failed with exit status: 1

  Similar error messages occurs when I revert to tag 8.21, which is
  1cb8e6392c70dca8773c411d4c824ad98b0fc1ec.

  But When I revert to several years before, say
  6eb57b59add3f7c7c70c0c6579efd0809b0632e0(Tue Jun 22 15:00:53 2004
  +0000), everything goes all right.

  Also when I use the source package from Ubuntu mirror(coreutils-8.13),
  autoreconf also works(in fact, there is already a configure inside the
  root directory of the source code).

  So why the git mirror of coreutils doesn't contain "m4/cu-progs.m4"?
  And what should I do to handle it?

  Thanks,
