Isn't that nice candidate for gnulib then?  I feel this is quite useful
piece of code.  But it may be that gnulib project is too careful to
incorporate this..

Yes, maybe not complete list of warnings/errors:

  $ cat test.sh
  #!/bin/bash

  WHERE=`mktemp -d`
  pushd $WHERE
  git clone git://git.savannah.gnu.org/tar.git
  cd tar
  ./bootstrap && autoreconf -vfi && ./configure && make -k
  popd
