I've followed these instructions and made the commits.

I noticed another warning when running "configure" while trying to spot the
error message that you reported:

configure.ac:145: warning: ill-formed serial number 'number', expecting a 
version string with only digits and dots

This error message is from aclocal.

$ aclocal --version
aclocal (GNU automake) 1.16.5
Copyright (C) 2021 Free Software Foundation, Inc.

Line 145 is newly added:
> +# serial number (from gnulib) to an older serial number (from gettext).

The comment is being interpreted as some kind of serial number line.
I will amend the comment to stop this.
