The bootstrap code is broken since 11-12-17 when Jime Meyering
tampered with AUTOPOINT and AUTORECONF:
configure.ac:152: error: possibly undefined macro: gl_FUNC_READLINE
configure.ac:176: error: possibly undefined macro: AC_DEFINE
Please update.
./bootstrap is updated from gnulib when your gnulib tree has a new
version, if Jim broke it please report it to bug-gnulib. What you can
do is create .bootstrap, with the following content:
bootstrap_sync=true
And revert bootstrap to the version in our repository.
