Please add the files
codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4
progtest.m4
from the /usr/share/aclocal directory to your autoconf macro directory or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.
Its does not appear to be an error, and can safely be ignored. However, it is confusing so I've addressed this by silencing its output in commit c46a384eb8c9bb41b134df0d0e84ed02cd49ecdc.
