Details:

Running 'autoreconf -fiv' on coreutils creates a configure script that fails:

/configure: line 6425: syntax error near unexpected token
`ac_cv_prog_cc_stdc=$ac_cv_prog_cc_c89'
./configure: line 6425: `ac_cv_prog_cc_stdc=$ac_cv_prog_cc_c89'

I could not find any reference to this in configure.ac, but the offending part
of configure is:

for ac_arg in '' ac_prog_cc_stdc=c89
 ac_cv_prog_cc_stdc=$ac_cv_prog_cc_c89
do
  CC="$ac_save_CC $ac_arg"
  if ac_fn_c_try_compile "$LINENO"
then :
  ac_cv_prog_cc_c89=$ac_arg
fi
rm -f core conftest.err conftest.$ac_objext conftest.beam
  test "x$ac_cv_prog_cc_c89" != "xno" && break
done
---
I can fix this manually by changing to:

ac_cv_prog_cc_stdc=$ac_cv_prog_cc_c89
for ac_arg in '' ac_cv_prog_cc_stdc
do
...

but that is not a good solution.

More info is available upon request.

This should be a gnulib bug fixed in

Yes, this fixes coreutils.  The problem of course is that every package that
uses gnulib has to update.

That's why we have a Gnulib. :-)

More precisely, if you want to use the latest Autoconf you should also use the
latest Gnulib. If you don't need to use the latest Autoconf, older Gnulib will
do.

I am not the maintainer.  At linuxfromscratch we show users how to build about
1000 open source packages, but we rely on the upstream source code.  Most of
the time upstream releases the package so that autoconf or autoreconf is not
needed by us, but sometimes we do need them. For those cases where it is
needed,  having different packages use different versions of gnulib makes
things difficult.

I will note that mozilla packages (firefox, seamonkey, thunderbird) still
require autoconf-2.13.  

There is not a lot autoconf developers can do about that, but it certainly
would be easier if gnulib could be installed system wide.

I do have a workaround for coreutils, so you can close this ticket.

FWIW this is fixed in autoconf git.
