These files do change from time to time, in ways that are important; for
example, config.guess and config.sub are updated to support new
architectures or new variants of existing architectures. It's best to
have this done automatically rather than doing it once manually and then
forgetting about it.
We could have a temporary directory in which we run automake, just for
the purpose of getting hold of these files. Perhaps something like this:
rm -rf automake-tmp
mkdir -p automake-tmp
cat >automake-tmp/configure.ac <<EOF
AC_INIT([temporary], [0.1])
AC_CONFIG_AUX_DIR([.])
AM_INIT_AUTOMAKE
AC_CANONICAL_BUILD
AC_CONFIG_FILES([Makefile])
EOF
touch automake-tmp/Makefile.am
(cd automake-tmp && aclocal && automake -a -c -f --foreign)
cp -a automake-tmp/config.guess automake-tmp/config.sub \
automake-tmp/install-sh automake-tmp/missing \
.
rm -rf automake-tmp
I don't know whether this is worth it, but it would be possible.
