Your package fails to build with the newest upcoming autoconf-2.71, which is part of a wide Fedora change. Please see the attached copr: https://copr.fedorainfracloud.org/coprs/odubaj/autoconf-2.70/packages/. More information about testing your package when building with autoconf available here: https://fedoraproject.org/wiki/Changes/Autoconf_271#How_To_Test
Thanks for a bug reoort. I fixed it with commit: https://src.fedoraproject.org/rpms/openchange/c/8231ec4c2e7e0c701982fe441a858ecf721fa07e?branch=rawhide I didn't build the package yet, I guess it can wait.
