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

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
