I am remaking these commits again after reverting them, but there is
another problem.  The "autogen.sh" script at the root of the
Texinfo repository runs autoreconf under tp/Texinfo/XS.  Now it runs
autopoint:

$ autoreconf --force --verbose --install
autoreconf: export WARNINGS=
autoreconf: Entering directory '.'
autoreconf: running: autopoint --force
Copying file config.rpath
Copying file gnulib/m4/gettext.m4
Copying file gnulib/m4/host-cpu-c-abi.m4
Copying file gnulib/m4/iconv.m4
Copying file gnulib/m4/lib-ld.m4
Copying file gnulib/m4/lib-link.m4
Copying file gnulib/m4/lib-prefix.m4
...

This is due to the use of AM_GNU_GETTEXT_VERSION that has been added to
tp/Texinfo/XS/configure, which autoreconf scans for.  Some of these
copied files are downgrades.

I can change autogen.sh to avoid these downgrades.  There is
already a comment in autogen.sh to explain why autoreconf is not
run at the top level.
