Please show the exact steps you use to build the cups package and the
exact error message you get.

Technically you are correct because configure.ac has AC_PREREQ([2.71]).
But autoconf is pulled in by the automake which is listed as BuildRequires
in cups.spec file, and since Fedora rawhide only has
autoconf-2.71-5.fc38.noarch, there really is not an older autoconf around
to ruin your day.

I suspect he may be trying to rebuild the Fedora CUPS RPMs on a RHEL 8 or 9 based machine.

Ironically CUPS 2.4.x doesn't actually need autoconf to be at least 2.71, on openSUSE they have a downgrade-autoconf-requirement.patch file which downgrades the requirement to 2.69:
